@chapter Overview
@cindex what is this?
Welcome to Background Debug Mode (BDM) support for GDB. BDM is emulator
or debugger support in a range of Motorola processors. This package
deals with the CPU32, and Coldfire family of processors. PowerPC
processors are not supported by this package.
CPU32 processors were the first processors to appear with BDM
support. The Coldfire family's BDM module is similar to the CPU32 family
of processors. The CPU32 has the BDM module integrated into the
processor core. The Coldfire is more modular. The debug module is
separate to the core.
BDM is not JTAG debugging although a serial bug is used. JTAG is a
standard and operates differently to BDM. BDM uses high level commands
to control the device. You do not need to clock in and out a loop of
registers.
BDM is accessed on the procesor via a three wire serial bus. The signals
are a clock, data in and data out. Various other support signals
exists. This are used to place the processor into BDM, break the
prcessor, or monitor the status of a running processor.
The CPU32 standard BDM connector is not the same as the Coldfire
connector. You need separate plug on modules for each processor
family. Check the POD you use matches the processors voltage and clock
speed. This is import for Coldfire users.
Coldfire BDM has support for realtime trace. This package does not
support realtime trace.
Coldfire BDM can operate in a limited manner while the processor is
running. The BDM module being separate from the procesor core allows
this feature.
History
Gunta Magna contributes here is a bit of history of how GDB and BDM
came to light due to mutual support.
Somewhere in 1994/1995 Gunta Magna wrote (with the help of Michael
Schraut, at that time a student at lpr.e-technik.tu-muenchen) a first
version of the m68k Linux BDM device driver. This driver heavily based
on the work of Scott Howard (scott\@objsw.com), who wrote BD32, a DOS
tool to access 683xx controllers via BDM. He made the driver available
in source form, so I could use them. Scott is currently maintainer of
the crossgcc mailing list (http://www.objsw.com/CrossGCC/).
Additionally Gunta Magna wrote a BDM backend for gdb-4.13. (Note: Eric
credits M.Schraut falsly as the author of the GDB patches in the header
files. This went through until Chris Johns's version for Coldfire).
The driver was only for BDM interfaces compatilble to AN1230, aka as PD
interfaces. Scott supported also the ICD compatible interface, but due to
lack of equipment at that time Gunta Magna did not include that.
Eric Norum used those sources to port it to NextStep. He did not like
my way of interfacing driver and application, and designed a new
interface. He also introduced an abstraction layer, enabling other
applications than gdb to take advantage of the BDM driver. He also added
support for 68360, which is different in detail from the 68332 version
(MBAR support).
In 1996, Gunta Magna upgraded his driver to ICD by a compile time
option, and fixed some errors. He also upgraded the gdb backend to
gdb-4.16, introducing Eric's idea of the abstraction layer. Sources for
that can be found at the ftp server of lpr.e-technik.tu-muechen.de
In 1997 Eric went Linux and ported his NextStep driver to Linux. He
also wrote/ported his NextStep gdb backend, incorporating some of the
ideas (and bugs) introduced in Gunta's 4.16-version. He also published a
schematic stemming from the Motorola customer center here in Munich
(bd32new) (See below).
In 1997 I upgraded my driver to simultaneously support ICD and PD
interfaces. The selection is made by accessing different minor numbers.
This version has been handed out to several testers (including Chris
Johns), but has never been officially released.
Chris Johns used Eric's driver and added Coldfire support.

@cindex hardware
Various means exist to access a BDM port on a processor. This driver
provides support for various host operating system, and adapator boards.
The driver support the IDC hardware. A circuit abd PAL equations are
provided in the package.
The Coldfire support is via the P&E standard interface. You can find
information about these adaptor from the P&E web site.
<more on CPU32 hardware>
Coldfire
The Coldfire has a 26pin header. The expanded connector is for the
realtime trace. These signals are the PST or processor status
signals. Four of these signals provide provide the status of the
processor in realtime.
The 5206 and 5206e processor share the PST signals with the parallel
port on Coldfire. Anr application that uses the Coldfire's parallel
port, cannot relying on the PST for the realtime status of the
processor. The P&E module provides a processor halted signal to the PC's
parallel port based on the PST signals. The P&E Windows driver and DLL
use this signal. Using this software with the P&E interface and a 5206
variant of Coldfire requires the parallel port to left for the PST
signals. The PST signals on the 5307 processor are not shared. They are
free to be used for debugging.
This driver does not require the use of the PST signals. The parallel
port on the 5206 processor can be used as a parallel port.
The 5206 and 5206e differ in Vcc voltage. The 5206 is a 5.0V processor
while the 5206e is a 3.3V processor. You need to check your POD can
handle your processors voltage. The 5206e can operate at 54MHz. The 5307
operate at 70MHz. The processor clock is carried up the BDM cable to the
POD. You need to insure the PLD on the POD is fast enough and the cable
from the target to the POD is not too long. If the cable is too long or
the PLD marginal the processor clock could be dragged out of shape
causing various problems which can be hard to find.
Various people have reported problems when using the driver with 5307
processors. Building the driver with the Makefile define @code{USE_PST}
causes the problem to go away. The error is

This section covers building and installing the GDB server.
Currently only a Unix version exists. It should operate on any platform

bdm 6543/tcp # BDM server
@end smallexample
The port number @code{6543} was a random selection. If for any reason it
is a bad or taken number, please let me know.
In the file @file{/etc/inetd.con} add the following line :
@smallexample
bdm stream tcp nowait cjohns /usr/local/sbin//bdmd bdmd
@end smallexample
I am running this server as me. If the BDM devices have global
read/write enabled, then it should be ok to use the user @code{nobody},
or something similar as the user.

Your bug reports play an essential role in making @code{MRB} reliable.
Reporting a bug may help you by bringing a solution to your problem, or
it may not. But in any case the principal function of a bug report is
to help the entire community by making the next version of @code{MRB}
work better. Bug reports are your contribution to the maintenance of
@code{MRB}.
In order for a bug report to serve its purpose, you must include the
information that enables us to fix the bug.

@itemize @bullet
@item
If the you select a particular configuration and @code{MRB} does not
build. It should build if the configuration parameter selection make
sense. For example building the networking code without configuring a
network driver.
@item

@node Bug Reporting
@section How to report bugs
@cindex bug reports
@cindex @code{MRB} bugs, reporting
The fundamental principle of reporting bugs usefully is this:
@strong{report all the facts}. If you are not sure whether to state a
fact or leave it out, state it!
Often people omit facts because they think they know what causes the
problem and assume that some details do not matter. Play it safe and
give a specific, complete example. That is the easiest thing for you to
do, and the most helpful.
Keep in mind that the purpose of a bug report is to enable us to fix the
bug if it is new to us. Therefore, always write your bug reports on the
assumption that the bug has not been reported previously.
Sometimes people give a few sketchy facts and ask, ``Does this ring a
bell?'' Those bug reports are useless, and we urge everyone to
@emph{refuse to respond to them} except to chide the sender to report
bugs properly.
To enable us to fix the bug, you should include all these things:
@itemize @bullet
@item
The version of @code{MRB}.
Without this, we will not know whether there is any point in looking for
the bug in the current version of @code{MRB}.
@item
Any patches you may have applied to the @code{MRB} source.
@item
The type of host machine you are using, and the operating system name
and version number.
@item
What compiler (and its version) was used to compile @code{MRB}
--e.g. ``@code{gcc-2.7}''.
@item
The target you are building. If this is a new target you are developing,
you may need to provide some details of the changes you have made.
@item
A description of what behavior you observe that you believe is
incorrect.
@item
If you wish to suggest changes to the @code{MRB} source, send us context
diffs, as generated by @code{diff} with the @samp{-u}, @samp{-c}, or
@samp{-p} option. Always send diffs from the old file to the new file.
If you even discuss something in the @code{MRB} source, refer to it by
context, not by line number.
The line numbers in our development sources will not match those in your
sources. Your line numbers would convey no useful information to us.
@end itemize
Here are some things that are not necessary:
@itemize @bullet
@item
A patch for the bug.
A patch for the bug does help us if it is a good one. But do not omit
the necessary information, such as the test case, on the assumption that
a patch is all we need. We might see problems with your patch and decide
to fix the problem another way, or we might not understand it at all.
And if we cannot understand what bug you are trying to fix, or why your
patch should be an improvement, we will not install it. A test case will
help us to understand.

This driver uses different API than Chris's tool-chain.
Code is there to:
* provide support for people using this branch
* archival purposes
* as source for integration of same features
(DEVFS, PARPORT) into Chris's driver.

Plain gdb and insight (that is the GUI extended gdb) can be built with
just one build: download insight-5.3 instead of gdb-5.3. Then apply both,
gdb-5.3-bdm-683xx-patch and insight-5.3-bdm-683xx-patch. This builds
m68k-bdm-coff-gdb (this is plain gdb) and m68k-bdm-coff-insight (this is
GUI-enabled gdb)
To get insight running I needed to put the following into my .gdbinit68 file:
set prompt (gdb-bdm)
set hash 1
bdm_log off
bdm_setdelay 0
bdm_autoreset on
bdm_timetocomeup 0
bdm_load_use_lma 1
#target bdm /dev/pd_bdm0
target bdm /dev/icd_bdm0
bdm_debug_driver 0
# this macro is called by insight directly after attaching to target but
# just before the processor is let to run.
#
define reset
bdm_reset
bdm_entry gdb_entry
set $pc = gdb_entry
set $vbr = __s_text
set $sp = ((unsigned long *)$vbr)[0]
#
# insert breakpoints on positions that indicate big trouble.
#
delete
break excpt_handl
break halt_system
break uninit_irq
end
There is still a problem with insight: On start up insight sometimes get
into an endless loop trying to read a cycle of stack frames. I don't know
what triggers this loop, but when it happens once it is perfectly
reproducable. Deleting ~/.gdbtkinit helps in this case, but I have no idea
why it helps.

This version of BDM driver is updated to be compatible with
the most of existing kernel versions. Main focus has been oriented
to 2.2.x and 2.4.x, but most of other unstable and stable kernels
back to 1.3.x stone age should be supported.
Driver needs to find kernel sources to compile.
You may need to edit "Makefile-mod" for some strange kernel
sources locations. There is automatic location selection depending
on current kernel version and "/lib/modules" structure.
It select next kernel souces directory for older kernels
KERNEL_LOCATION=/usr/src/linux
it uses more reliable way of build process for
new modules hierarchy
KERNEL_LOCATION=/lib/modules/$(CURRENT)/build
*** BDM driver autoloading ***
No longer su to root, insmod the module of choice, and then start the
debugger as user-joe, but just start the debugger, and the necessary
modules get loaded automatically.
What do you have to do?
* You need to copy the device driver code to
/lib/modules/<kernel-version>/misc
for 2.4.0 kernels use
/lib/modules/<kernel-version>/kernel/drivers/char
* edit /etc/conf.modules
(see my local /etc/conf.modules as an example)
* do a "depmod -a".
* Start "kerneld" at an early boot stage
or enable "kmod" in kernel configuration in section
"Loadable module support".
For more details on dynamic kernel module support, see the READMEs
in the latest modules utilities. The current release is modutils-2.4.22.
*** IMPORTANT ***
The bdm driver checks if the required resources (here only the io-port
addresses) are in use, e.g. by the lp device driver or a parallel port
ethernet device. When everything is free, it reserves these resources, and
releases them when closing the device. So no double access should be possible.
If BDM driver is compiled without PARPORT support, there could be problem
with "parport", "parport_pc" and "lp" module stack resource reservation,
which could compete with "m683xx-bdm" driver. Compile "lp" and "parport"
as modules in such case and unload them before "m683xx-bdm".
Opposite is true in the case of BDM driver with PARPORT support.
You need "parport_pc" compiled into kernel or as module.
Possibilities reworded
A) You need to rmmod parport, if you have compiled BDM driver WITHOUT parport
support. It can be done by next line added to "/etc/modules.conf"
pre-install bdm /sbin/modprobe -r lp parport_pc
B) If BDM driver is compiled WITH parport support, the "parport_pc" module
have to be loaded before "bdm" one. It is loaded by boot process in the
most cases but next line in "/etc/modules.conf" doe not hurt
below bdm parport_pc
** DEVFS support ***
Driver supports new "devfs" virtual device filesystem found in
2.4.0 kernels. There are compiled-in next device names for those
kenels "/dev/m683xx-bdm/pd0" and "/dev/m683xx-bdm/icd0" etc.
You can add next line to "/etc/devfs.conf"
LOOKUP m683xx-bdm MODLOAD
Next line helps to connect simple "/dev/bdm" name for right configuration
LOOKUP m683xx-bdm EXECUTE /bin/ln -s ${mntpnt}/m683xx-bdm/icd0 ${mntpnt}/m683xx-bdm
There are lines for "/dev/modules.conf" with aliases for different kernels
# m68k BDM
alias /dev/bdm m683xx-bdm
alias /dev/m683xx-bdm m683xx-bdm
alias char-major-53 m683xx-bdm
# the next line is required/usable for BDM driver compiled without
# parport support. You might want to remove this line if you get errors
# about unresolved symbols when the driver is loaded.
pre-install m683xx-bdm /sbin/modprobe -r lp parport_pc

BDM-LOAD snapshot 2003-08-15
This is attempt to rewrite bdm-load utility for 683xx based
embedded systems.
This code is in experimental and rewrite phase, it works for me,
but there is no warranty that it is useful or safe for others.
Except "bdm-load" program, two test utilities are build.
It is "bdm_test" program. It was my first experiment with
interfacing BDM library with stand-alone program.
The second project is to write free TPU debugger, but this
code does not do anything useful yet.
INSTALL
To compile and install "bdm-load" you need:
- mc683xx target system with BDM interface
- GCC compiler for your Linux system.
- BDM driver - latest version is attached into "bdm-load" archive
- BFD object file handling library
- some time and experience with Linux system and make utility
To be able load other formats than S-record and IntelHEX, you
need to link with BFD library with m68kcoff and/or m68kelf
targets. I have system wide BFD with all targets I use.
I build my Linux binutils configured by next line in created
source tree subdirectory i586-linux
---System wide multi binutils configuration-----------------------
../configure \
--with-ld --exec-prefix=/usr --prefix=/usr \
--enable-shared --enable-commonbfdlib --verbose --with-mmap \
--enable-targets=i586-pc-linux-gnulibc1,i386-a.out-linux,i386-coff,\
m68k-linux-elf,m68k-coff,m68k-a.out-linux,h8300-hitachi-coff,\
sparc-linux-elf,i586-win-pe,tic30-ti-coff,tic30-ti-aout
------------------------------------------------------------------
You need not to rebuild your system wide BFD. You can statically link
with "libbfd.a", "libiberty.a" and "bfd.h" taken, for example,
from GDB build tree configured for m68k-coff. Configuration of GDB
is bellow
---GDB for m683xx with BDM configuration--------------------------
../configure --target=m68k-bdm-coff --enable-gdbtk --with-x --verbose \
--enable-targets=m68k-linux-elf,m68k-coff,m68k-a.out-linux
------------------------------------------------------------------
To compile statically copy three needed files to gdblibs subdirectory
and change next lines in "Makefile" to form
CFLAGS += -I ./gdblibs
#LDFLAGS += -lbfd -liberty
LOCLIBS += ./gdblibs/libbfd.a ./gdblibs/libiberty.a
Prebuild version of "bdm-load" is attached to archive under name
"bdm-load-i586-linux-static".
PROGRAMMERS NOTES
Sources of "bdm-load" are in next files
bdmlib.c,bdmlib.h library for communication with CPU32
through BDM
bdmflash.c,bdmflash.h flash write and erase algorithms and
flash areas write filter routines
bdm-load.c loader command line and interactive
interface
It is necessary to add new entries into array flash_alg_infos_def
in "bdmflash.c" file for every new flash programming algorithm.
Flash types should be sorted from smallest to biggest.
RUNNING BDM-LOAD
Command line interface
Usage bdm-load [OPTIONS] file1 ...
-h --help - this help information!
-i --init-file=FILE - object file to initialize processor
-r --reset - reset target CPU before other operations
-c --check - check flash setup (needed for auto)
-e --erase - erase flash
-b --blankck - blank check of flash
-l --load - download listed filenames
--go[=address] - run target CPU from entry address
-M --mbar=val - setup 68360 MBAR register
-s --script - do actions and return
-d --bdm-delay=d - sets BDM driver speed/delay
-D --bdm-device - sets BDM device file
-f --flash=TYPE@ADR - select flash
For flash TYPE@ADR can be
{<TYPE>|auto}[@{csboot|cs<x>|<start>{+<size>|-<end>}}]
Examples
auto@csboot amd29f400@0x800000-0x87ffff auto@0+0x80000
If auto type or cs address is used, check must be
specified to take effect.
Known flash types/algorithms :
amd29f010x2 amd29f040 amd29f400 amd29f800 at49f040x2 amd29f080x4
Possible commands in interactive mode :
- run
starts CPU32 execution at address taken from last downloaded
object file. If no file is loaded, it starts at address
fetched during last reset command.
- reset
resets CPU32 and if no entry address is defined, PC address is
remembered
- erase
sets erase request and starts erase procedure
-load [<object-file>]
sets load request and starts download of files from
object file list.
if <object-file> is specified, object file list is cleared
and specified file is added on-to list
- exit/quit
exit interactive mode and return to shell
- dump <address> <bytes>
dumps memory contents from specified address.
bytes specifies number of bytes to print.
- stat
shows CPU32 state, does not require CPU32 to stop
- check
checks flash memories at specified ranges,
if auto type or "cs" address is specified for some
flash, CS address is fetched and flash autodetection
is run
- autoset
same as check, but all flash types are revalidated
- stop
stops CPU32 and clears all reset, erase, load and run
requests
- make
make in current directory is called
The simplest way to initialize CPU32 chipselect subsystem
and other SIM parameters is to provide "cpu32init" file
in same directory as "bdm-load" is started from.
The "cpu32init" file is processed at every reset of target.
The syntax of the macro file is:
<cmd-letter> <num1> <num2> <num3>
The nums are either in hex (form 0x), in decimal (form 123) or in octal
(form 0234)
The meaning of the nums depends on the command letter:
w or W means: (write)
write to address (num1) contents (num2) length is (num3) bytes. Only
1, 2, 4 bytes are permitted.
z or Z means: (zap, zero)
fill memory area beginning at (num1) with byte value (num2) length
(num3) bytes.
c or C means: (copy)
copy memory area from (num1) to (num2) with length (num3) bytes.
m or M is new command to set 68360 MBAR register.
the MBAR register is set to value of (num3)
Empty lines and lines with a leading '#' are ignored. See GDB-BDM
patches for more information.

/*
Revision history
2001-01-16 Added experimental support of single 8 bit flash memory
based on Avi Cohen Stuart <astuart@baan.nl> changes
2001-07-10 Added support for amd_29f010 with x8x2 configuration
based on John S. Gwynne <jsg@jsgpc.mrcday.com> changes
Trying to solve x8x2 race condition with shortest
possible code - needs more tests
2001-08-30 Added alg-info for at_49f040 with x8x2 configuration
x8x2 configuration needs more testing, may be broken
2003-05-19 Added initial support for x32 memory configurations.
The x16x2 and x8x4 should work as well. Changes were
motivated by Andrei Smirnov <andrei.s@myrealbox.com>
code, but his small update results in deeper code redesign.
This could enable to support page writes for modern versions
of FLASH memories in future.

BUGS
====
- Missing 5282 support (patch needed).
- Duplicated debug output on windows.
- PCI parallel ports with non-standard port-addresses not supported.
- Probing of different access methods (driver, ioperm, bdmd) with
irritating error messages.
This one and the PCI parallel ports above would probably best be resolved
by a new naming sheme for the target devices.
- In insight-5.3, when "Run" button is hit, no bdm_reset is executed. This
leads to the effect that _first_ "Run" works (since you can/should put
bdm_reset into the setup-and-load macro). But the _second_ "Run" will
fail since IRQs are left enabled and some registers are writeable only
once after reset.
- Insight-6.0 don't work at all.
- The target is hardwired to /dev/bdmcf0 in insight.
- Parallel port on Elitegroup ECS K7S5A (sis735 chipset) motherboard seems not
to work. The port pins are active only for a couple milliseconds after an
edge of the strobe signal and set tri-state thereafter. The bdm adaptor
requires that the pins have valid signals all the time. Tri-stating the pins
result in loss of control over the adaptor/target.
- Dell Pentium III machines seem to not work. Not really sure why but clearing
the parallel port register for the CF processors causes the parallel port to
either initialise or reset and not work.
- Coldfire - support to detect version of the debug module for auto detection
of the PST lines has problems if a BDM pod is not connected to the target or
the target is not powered.
- The 5407 BDM hardware does not implement the SSI bit and the driver tries to
use it. No idea why this bit was removed as it was just stupid. The work
arounds for the driver are complex and not yet implemented.
- For m68k ELF systems you need to be careful about the binutils mix you use.
Binutils of versions 2.9.5.* will not work with gdb-4.18 or earilier. You
will get core dumps. Earilier version of gcc and binutils as used by the
ucLinux project have some problems.
---------------------------
Reporting Them:
If you've got any questions/remarks about any of this, please contact the BDM
project mailing list on the SourceForge web site:
http://sourceforge.net/projects/bdm/
It is a good idea to turn on the debug and look at the output. Keep
the log as it might be useful for us to track the problem down.
A patch is also welcome.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

BDM GDB DRIVER AND LIBRARY PACKAGE
==================================
INTRODUCTION
============
This package contains everything you need to know to be able to run GDB on
Linux, FreeBSD, SCO Unix, and Windows and control a Motorola CPU32+ (68360) or
Coldfire (V2/V3/V4) target through a standard PC parallel port or via a USB
pod.
o The CPU32 interfaces supported are PD and the IDC interface. GDB
should now operate with the CPU32 processor without error.
o The Coldfire interface is the TBLCF USB pod or P&E parallel port type
interface.
o You can build Insight if you apply the Insight patch. See the
Insight README in this directory.
o For WindowsNT or Window2000 you will need the GiveIO package. You
are best to search the net for the GiveIO (giveio.sys) package. You
will also need the INSTDRV.EXE file that is also available on the net.
GiveIO has been test on Windows 2000 and Windows XP.
o For Unix users the library is built with I/O perm support by
default. The same library allows an application to directly
access the hardware or use an installed BDM kernel driver. On FreeBSD
this the "/dev/io" support.
I/O Permission is a means of getting at the parallel port hardware
without the need for a kernel driver. This BDM package still provides
support to build a kernel driver, but you do not need to if you want to
avoid kernel drivers. Some people wish to use kernel drivers and some do
not.
If you wish to learn more about I/O Perm support please refer to the
section at the end of the file.
You can disable I/O perm support by editing the Makefile. It is hoped
autoconf support in the future will provide a better way to handle this.
o To support the TBLCF UDB pod you will need the libusb package. For Windows
this means the LibUSB-Win32 package.
o Support for an initialisation script called '.m68kbdminit'. See the
section on Initialisation Scripts.
The subdirectories contain:
config
Autotools support files.
driver
Source for a Linux, SCO, FreeBSD, I/O Perm, and Windows BDM device
driver module.
gdbPatches
Move to outside this tree. Please refer to the Sourceforge
project for the patches.
gdbScripts
Example GDB command scripts that show how to initialize and run
a Motorola 68360 system using standard GDB commands.
gdbserver
A GDB Remote protocol server. Needs GDB 6.7 or later.
lib
User-level library routines for accessing the BDM device driver.
flashlib
Library for flash support. This library currently supports host-only
and host-assisted operation modes of 29Fxxx and 49Fxxx chips in
any combination of bus_width=[1|2|4] and chip_width=[1|2|4]. It is
already prepared for target-only operation mode and addition of different
flash algorithms.
local_scripts
Scripts to run on the host machine the driver is being installed
on.
server
The BDM server. This is a daemon which interfaces to the local BDM
driver remotely. The BDM library can be built to support local and remote,
just local or just remote access.
tblcf
The TBLCF code from Daniel Malik. It include the various tools for managing
the pod.
test
Programs to test the BDM library and driver routines.
utils
contains some utilities which might be useful.
README Files
============
There are 4 README files which document the BDM package. They are:
o README
This is the top level README file and the one you are currently readling.
o README.cvs
If you use the code from CVS you should read this file. It explains how
to bootstrap the package to create the configure script and Makefiles.
o README.bdmgdbserver
This file documents the BDM GDB Server. It explains why you should use
the BDM GDB Server to interface to GDB and how to build GDB.
o README.insight
This is an old README and may be useful to anyone still wanting to
use Insight as a GUI interface to GDB. A current Insight with a current
GDB should work with the BDM GDB Server.
WINDOWS
=======
Windows is supported on Windows 98, Windows 2000 and Windows XP. It may run on
other version of Windows, but the ones listed have been tested. Windows 2000,
Windows XP and beyond need to the GiveIO driver to gain direct access to the
parallel port hardware if you are using a parallel port pod. A USB pod need the
libusb software for Windows.
You can download the GiveIO package from the net plus you will need the
INSTDRV.EXE program. To install GiveIO place the 'giveio.sys' and INSTDRV.EXE
in a directory and log in as an Administrator or equivalent then:
c:\tmp> insdrv givio c:\tmp\giveio.sys
The package builds under Cygwin and MinGW.
The MinGW support provides you with a version that directly accesses the
Windows APIs and does not need a Cygwin DLL. To build with MinGW you need to
get the MinGW and MSYS packages from the MinGW web site:
http://www.mingw.org/
The MinGW package provides the compiler and MSYS provides a shell capable of
running the configure script.
To build the TBLCF USB pod support you need to obtain the LibUsb-Win32 package
from:
http://libusb-win32.sourceforge.net/
Click the Downloads link and move the Sourceforge download page then select the
libusb-win32-device-bin package. I have tested with the 0.1.12 version. Unpack
the tar file to a directory on your machine ready to use. Make sure you do not
have any spaces in the path. Spaces cause problems with the autoconf test for
the libusb library.
QUICK START
===========
You have unpacked the package. Next to the top of the package create an empty
directory and enter it, configure the package, make, then install.
$ tar xzf bdm-xx.tar.gz
$ mkdir build
$ cd build
$ ../gdb-bdm-xxx/m68k/configure
$ make
$ make install
Note: this process by default creates an IOPERM type parallel BDM driver and a
TBLCF USB driver. If you wish to build a Linux kernel driver please follow the
INSTALLATION directions.
INSTALLATION
============
The Makefiles in all the subdirectories are set up to install their
results in /usr/{bin,lib,.....}.
On FreeBSD remember to use `gmake' rather than `make'.
Notes:
1. For Windows move to Step 2 as the driver is built into the library. You
may also need to add `CC=gcc' to make's command line.
2. For I/O Permission or USB users move to step 2 as the driver is built
into the library.
3. Driver users will still have a library with I/O perm support unless the
default of the library Makefile is manually changed.
4. You can specify a different `prefix' for the installation directory by
running all the `make install' commands described below as:
$ make prefix=/some/directory install
Step 1 -- Compile and install the BDM device driver
If you do not wish to use a driver and just want the I/O perm support move to
Step 2.
Make sure the kernel source code is installed under the /usr/src path.
Support for more than Linux has been added. You must enter the OS specific
directory then enter the make command. We assume Linux for the remainder of
this file.
If your Linux kernel has been configured for module versions you must
uncomment the #MODVERSIONS=-DMODVERSIONS line in driver/linux Makefile. If
the kernel is configured for module versions and you fail to uncomment this
line the driver will install and work properly, but depmod will complain
about unresolved symbols.
For Coldfire users the driver now looks for the debug module version and will
use the PST signals if it detects a version 1 debug module. The debug version
1 is found on the 5307.
Disable the TBLCF code with the configure option '--disable-tblcf'.
# cd driver/linux
# make all install
You may get a bunch of error messages like:
In file included from /usr/include/linux/fs.h:277,
from linux-bdm.c:63:
/usr/include/linux/hpfs_fs_i.h:5: parse error before `ino_t'
/usr/include/linux/hpfs_fs_i.h:5: warning: no semicolon at \
end of struct or union
/usr/include/linux/hpfs_fs_i.h:12: parse error before `:'
If this happens, try adding `-I /usr/include' to the beginning of the CFLAGS
definition in the Makefile in driver/linux.
A script is provided in `local_scripts' called MAKEDEV which create the
special files needed for the CPU32 and Coldfire.
To make the special files by hand you can enter:
# mknod /dev/bdmcpu320 c 34 0
^^ ^
| |
| +--Minor device number (see below).
|
+--This value must match the
BDM_MAJOR_NUMBER in driver/bdm.h
To have the module module loaded by kerneld when needed
adding to /etc/conf.modules the line:
alias char-major-34 bdm
To automaticially load the driver into the kernel every time
you reboot you can add the line:
# /sbin/insmod bdm
to your startup script, such as /etc/rc.d/rc.local.
You will need to create the device names. The local script MAKEDEV can do
this for you:
# ./local_scripts/MAKEDEV
Step 2 -- Compile and install the library and user programs
The package provides a configure script that you use to build the
package. All testing I have performed is not to build in the source tree. For
the default configuration just run the configure script:
$ mkdir build
$ cd build
$ ../gdb-bdm-xx/m68k/configure
You will need to change the 'gdb-bdm-xx' to the name of the directory in the
version of the package you have downloaded.
On Windows if building the TBLCF driver you need to provide the location of
the libusb package. The details to download and obtain the libusb package for
Windows is detail above. Provide the path to the top of the libusb package:
$ ../gdb-bdm-xx/m68k/configure \
--with-usblib-dir="c:/work/libusb-win32-device-bin-0.1.12.1"
The above command is run inside the MSYS shell.
Once the package has configured itself you can make it:
$ make
To install you may need to obtain the appropriate permissions. Once you have:
$ make install
The library can be built to access a BDM driver locally via the kernel's
driver interface, remotely via a TCP/IP socket interfacei, or with direct
hardware access via the ioperm system call. You can have a library which
supports all or a mix of interfaces. This allows you to build the
library and therefore gdb on a host which does not support the driver
interface.
On Windows 2000 install the GiveIO driver. This is detailed in the WINDOWS
section earlier. To install the USB pod on Windows refer the TBLCF Pod
section later.
The package supports a number of configuration options over and above the
standard configure options such as '--prefix'. These are:
--enable-debug: Turn on compiler debug information
On by default.
--enable-remote: Turn on the remote protocol and build it into
the library. On by default.
--enable-ioperm: Turn on direct IOPERM hardware access. Enabled
if the OS provides the ioperm() system call.
--enable-driver: Turn on driver access from the library. Enabled
by default on systems that support it.
--enable-server: Turn on building the BDM server. On by default.
--enable-flashlib: Turn on building of the flashlib.
--enable-bdmctrl: Turn on building of the bdmctrl utility. Since there
might be problems to locate bfd.h/libbfd.a which
know how to handle target object files, building
the bdmctrl utility is disabled unless you have
specified the configure options --with-libbfd,
--with-libiberty and --with-bfd-include-dir.
--enable-tblcf: Turn on building the TBLCF support. On by default.
On Windows the --with-usblib-dir can be used to
provide the location of the unpacked Win32 libusb
package.
--with-libusb-dir Path, with no spaces to the libusb library if the
library is not installed in the default location.
To turn off an option use '--disable-*' where '*' is one of the above.
Some host settings automatically disable some options:
Linux : All default settings.
Cygwin: All default settings.
MinGW : Server is not built.
The prefix defaults to the platform specific default. Please refer to your
documentation for this default setting or just try and see what happens.
Note, the BDM library is now installed under the package directory of 'bdm'
under the prefix. For example a prefix of '/usr/local' as found on Linux
results in the library being under '/usr/local/lib/bdm/libBDM.a'.
The BDM package also supports cross-compiling. For example you can build
for a mingw32 host on a Linux machine if you have a MinGW cross-compiler
and runtime installed:
$ ../gdb-bdm-xx/m68k/configure --host=ming32 \
--build=`./gdb-bdm-xx/m68k/config/config.guess`
Step 3 -- Installing the Server
You only need the BDM server if you intend to use the ioperm method of
accessing the parallel port, or you wish to support remote access. If you
wish to use a driver and your access is local to your development machine
then this step may be skipped.
Before using the server, please make sure you understand the implications
of such a setup. You probably want to restrict access to the bdmd port
to trusted machines.
The BDM server allows a lab to contain your target hardware and you can
access it from your development machine. The BDM server can support clients
on different platforms. This means a Linux server can be accessed from MacOS
or Windows clients.
The server runs from the xinetd or inetd daemon, and installs into
the 'sbin' directory under the configure prefix when building the user
programs in Step 2 above.
You need to edit the /etc/services file to add the port number bdmd
uses. Add this line at the bottom of the /etc/services file:
bdm 6543/tcp # BDM server
The BDM remote library will check /etc/services to see if a port is
provided. If not found the remote library will default to 6543.
It is recommended you add the entry to /etc/services and you check
the client and server match.
For inetd users such as FreeBSD:
You need to edit the /etc/inetd.conf file. Add this line at the end of
/etc/inetd.conf:
bdm stream tcp nowait root /usr/local/sbin/bdmd bdmd
You can specify any user including root. If you are wishing to use the
ioperm support then the user must be root.
For xinetd users as root install the follow in a file called:
/etc/xinetd.d/bdm
service bdm
{
socket_type = stream
port = 6543
wait = no
user = root
server = /usr/sbin/bdmd
server_args = -n
log_on_failure += USERID
disable = no
}
then get xinetd to reload its configuration.
To test the bdmd server open a shell on the machine bdmd has been installed
and condigured. At the shell prompt run telnet as follows:
$ telnet localhost bdm
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
>> helo
HELO 2 ted BDM server 1.0.0 ready.
>> quit
Connection closed by foreign host.
$
The lines marked '>>' you type and press enter. Once the connected to
localhost appears enter 'helo' and enter. The server should respond with
version etc. To exit enter 'quit' then enter.
If is not working you are best to check your system log (/var/log/messages)
to locate the reason xinetd is not starting the bdmd server. To debug an
xinetd setup, as root do:
# kill -SIGUSR1 $(pidof xinetd)
# less /var/run/xinetd.dump
The look for the BDM entry and check entry is correct. Here is an
example:
Service = bdm
State = Active
Service configuration: bdm
id = bdm
flags = IPv4
socket_type = stream
Protocol (name,number) = (tcp,6)
port = 6543
Groups = no
Bind = All addresses.
Server = /usr/sbin/bdmd
Server argv = bdmd -n
Only from: All sites
No access: No blocked sites
Logging to syslog. Facility = authpriv, level = info
Log_on_success flags = HOST PID
Log_on_failure flags = HOST USERID
running servers = 1
retry servers = 0
attempts = 0
service fd = 5
Step 4 -- (Optional) Testing the driver.
It a good idea to build and run the test program called `bdm-chk' for
Coldfire processors and 'bdm-cpu32-chk' for CPU32 processors. This will show
the library built correctly, the driver loads and functions, and your
hardware is connected correctly and functioning.
You will need to select the correct device for the Coldfire. The example
below is for the CPU32 interface on LPT1. To test a CPU32 processor do:
$ cd test
$ ./bdm-chk /dev/bdmcpu320
To test a Coldfire processor do:
$ ./bdm-chk /dev/bdmcf0
Note, the number at the end of the device path is the parallel
port number your pod hardware is connected too. The device nodes
start from 0, while the standard PC LPT ports number from 1. This
means '/dev/bdmcf0' will look for a Coldfire processor on LPT1.
For a TBLCF USB pod on Linux you need to set up udev to create a symlink.
The section 'TBLCF USB Support' details how to set up udev. The TBLCF tools
tblcf-show returns the following for a single pod connected to a Linux box:
$ ./tblcf-show
TBLCF Turbo BDM Light ColdFire Show
Found 1 device(s)
1: 001-012
There is one pod and the name is '01-012' and udev links this to
/dev/tblcf3. To run check using this pod:
$ ./bdm-chk /dev/tblcf3
Note, the name will change on Linux if you disconnect the pod and reconnect
it. If want to lock a name down you can use udev.
To test using a BDM server on a remote host call 'foo':
$ /bdm-chk foo:/dev/bdmcpu320
Note, do not use the MSYS rxtv shell to test from. It currently transforms
program arguments and the device path used in these example becomes
something very different.
Step 5 -- Patch your GDB distribution
Step 6 -- Compile and install the cross-GDB with BDM support
These step have been removed. We do not need to patch GDB any more. Use the
m68k-bdm-gdbserver executable with GDB built from the FSF sources.
Please refer to README.bdmgdbserver for instructions on using the BDM GDB
Server.
Step 7 -- (Optional) Install the GDB scripts
$ cd gdbScripts
$ make install
You will have to change the scripts to match your CPU32(+) hardware.
Step 8 -- Build a BDM interface
See the Schematics directory for an example circuit.
Step 7 -- Try it out
This is left as an exercise for the reader.....
INITIALISATION SCRIPTS
======================
The M68K BDM package supports initialisation scripts. The scripts are all
called '.m68kbdminit' and read from 3 locations during the bdmOpen call. The
locations are:
1. The current directory ($PWD)
2. The user's home directory as specified by the "HOME" environment
variable.
3. A user define location as specified by the "M68K_BDM_INIT" environment
variable.
The files are plain text files and are read into a character array on after
another. The '#' is a comment character and line continuation using the '\' at
the end of a line is supported.
The configurations supported are:
dev:
"dev user-name device-name"
A line starting with 'dev' followed by white space defines a device mapping
or renaming. The user-name is the name a user may use to reference a
device. The device-name is the name required by the hardware to access the
device. This can be used to map a difficult USB device name that libusb uses
to a simpler user friendly name. This helps users because the naming of USB
devices vary between host platforms. The device mapping also helps
configuration control of debugging scripts. A common script can reference a
name and each user in a team can place the actual device they use in the a
user specific file in their home directory.
TBLCF USB SUPPORT
=================
The TBLCF is the Turbo BDM Light Coldfire UDB Pod created by Daniel Malik back
in 2006. This is a GPL design for both hardware and software. It uses a small
microcontrolller and firmware in the pod and the open source libusb code to
provide the low level USB support on various hosts.
The supported hosts are Linux, FreeBSD, and Windows. The specifics of the hosts
make the set up different for each. The scripts support helps user isolate
their host specifics. USB device names are helped by the 'dev' entry in the
M68K BDM script files. These entries allow you to make a simpler entry for a
more complex name. Use the' tblcf-show tool' to dump the names of the USB
devices you need to pass to the BDM software. On Linux you may wish to use read
the Linux section and use the udev interface.
The USB support in the BDM package checks the device name against the devices
detected by libusb. Linux is an exception where special code is present to
handle udev created sym-links. The code will partial match the device node
against the libusb detected devices. For example if the libusb device node
found on Windows is 'bus-0-\\.\libusb0-0002-0x0425-0x1001' then you could use
'0002-0x0425-0x1001' to use the device.
If you are a CPU32 user and would like to look at supporting the CPU32
processor with this pod please contact the BDM mailing list.
Linux
-----
The USB pod is simple to support on Linux. Just plug it and check the kernel
messages:
$ dmesg | tail
usb 1-1.2: new low speed USB device using ehci_hcd and address 12
usb 1-1.2: config 1 interface 0 altsetting 0 endpoint 0x82 is Bulk; ...
usb 1-1.2: config 1 interface 0 altsetting 0 endpoint 0x2 is Bulk; ...
usb 1-1.2: configuration #1 chosen from 1 choice
usb 1-1.2: New USB device found, idVendor=0425, idProduct=1001
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=2
usb 1-1.2: Product: Turbo BDM Light ColdFire v0.4
usb 1-1.2: Manufacturer: Freescale
usb 1-1.2: SerialNumber: Turbo BDM Light ColdFire v0.4
You can see the pod has connected with address 12. Run the 'tblcf-show' command
to list the names of the pods as seen by libusb. If you disconnect the pod or
power cycle the pod or system the address of the pod can change. For example a
disconnect then reconnect moves the address onto the next number on my
system. This make it difficult to create scripts that take care of this.
The solution is to use udev. This is a user land system present on current
Linux systems that responds to and manages hot plug kernel events. The
Wikipedia page on udev (http://en.wikipedia.org/wiki/Udev) provide a nice
overview of udev.
Create a udev rule for the TBLCF pod to create a node in the 'dev'
directory. You can customise the node name used to suite your specific
needs. For me I have a single pod on my local Fedora Core 8 workstation and so
a basic setup is all that is needed:
# cat /etc/udev/rules.d/91-tlbcf.rules
SUBSYSTEM=="usb" ATTR{manufacturer}=="Freescale" \
ATTR{idVendor}=="0425" ATTR{idProduct}=="1001" SYMLINK+="tblcf%n"
Note: there is a single line in the actual file.
When I plug in my pod udev creates '/dev/tblcf3'. This is:
# ls -las /dev/tblcf3
0 lrwxrwxrwx 1 root root 15 2008-03-06 14:59 /dev/tblcf3 -> bus/usb/001/012
The USB support for Linux in the BDM package checks if the device node is a
sym-link. If it is the link path is read and checked to see if the prefix is
'bus/usb'. If it is the device is assumed to be a USB device and the trailing
part of the path is the device name returned by libusb. The USB driver will
attempt to open the device. This may fail if the user does not have
permission. In this case the bdmd server on the local host is used. This is
similar to the I/O Permission support.
With udev you can create device nodes with any name that suites. You can also
add more attribute checks to create a specific node. This allows for the
creation of nodes that match the function the pod is performing. In my example
above the number in the dev file is based on the USB port on the work station.
The udev configuration required varys for different types of Linux. Please let
me know of a configuration for your version of Linux and I will add it to the
list.
Windows
-------
Plugging the pod into a Windows machine brings up the standard Hardware found
installer dialog box. I have only done this when an Administrator and I suspect
you will need to be an Administrator because driver files are installed into
the Windows directory.
You need to have the LibUsb-Win32 package unpacked some where on your
machine. Typically you will have done this to build the BDM software and the
package links the libusb library. The BDM package has a axbdm.inf file and you
navigate the Hardware installer to say you have a disk then browse to select
the axbdm.inf file. The installer will then start to install the drivers and if
it cannot find the files it needs it will ask for them. This time navigate to
the location of the LibUsb-Win32 files and select the ones asked for by the
dialog box.
I created the axbdm.inf file for the AxBDM pod from Axiom I have. The
LibUsb-Win32 package contains a program called inf-installer.exe. To use this
program with the pod connected to the computer, run the program then select the
pod and fill in the fields.
Once finished you can run the testlibusb-win.exe and it will show the TBLCF pod
in the list of devices.
Run the tblcf-show program to get a list of detected pods. The returned name is
not pretty but it seems to be unique to pod in a specific USB port. You need to
use this name when using the BDM software:
> chk-bdm bus-0-\\.\libusb0-0002-0x0425-0x1001
It is not a nice name but this is what libusb returns. You can take this name
and place in a .m68kbdminit file to make more user friendly:
dev bus-0-\\.\libusb0-0002-0x0425-0x1001 usb1
On Windows you may need to add a HOME environment variable. You can do this
using the Control Panel's System entry. Open the System entry, select the
Advanced tab, then the Environment Variables button and add to "User Variables"
a "HOME" entry thats points to your home directory. On Windows this is
typically your "My Documents" directory. Once set you can create a .m68kbdminit
file in that directory and the M68K BDM tools will read that file when opening
a BDM device.
When using GDB you need to escape the '\' character. The above device name in
gdb and gdb scripts becomes:
bus-0-\\\\.\\libusb0-0002-0x0425-0x1001
I/O PERM SUPPORT
================
The I/O Permission support is based around the 'ioperm' system call on Linux
and the "/dev/io" I/O port access on FreeBSD. The calls allows a root executed
program direct access to the I/O ports of a PC. Unix programs such as X windows
use this call to gain control of the video card I/O ports without the need for
a driver. The term "ioperm" refers to the ioperm call on Linux and the
"/dev/io" interface on FreeBSD.
The support for the ioperm call has been added to the BDM package because it:
1. Allows a user to build a BDM application without installing kernel
sources.
2. The BDM driver is included in the user land application rather than
the kernel. A kernel upgrade or change does not require the building
of the BDM driver.
3. Binary programs can be created and distributed removing the need for
users to build a driver to use them.
4. Stops the kernel jitter seen when downloading.
The library that BDM applications link to by default now contains the ioperm
call as well as the BDM driver code. If you link the default library to GDB it
will contain the ioperm call. Having an application such as GDB make an ioperm
call will fail unless GDB is executing as root. The ioperm call requires the
program making the call be executing as root and executing GDB as root is not
recommended and is actively discouraged.
The remote protocol that is also built by default into the BDM library provides
an easy means to have GDB executing as a user and the BDM server executing as
root. The BDM server being root can make the ioperm call and gain direct
control of the parallel ports.
To use the ioperm call make sure you install the BDM server. See Step 3 of the
INSTALLATION procedure above.
The ioperm support performs the following when opening the BDM port:
1. Issue the ioperm call. If it passes the direct I/O accessing of the
parallel port is performed.
2. If the ioperm call fails, the kernel driver open is attempted. If
is succeeds the kernel driver is used.
3. If the driver call fails an attempt to connect to a local BDM
server is performed. Therefore if ioperm and driver opens fail the
following check command:
$ ./chk /dev/bdmcf0
is transformed into the equivalent command line command of:
$ ./chk localhost:/dev/bdmcf0
where we are attempting to open LPT1 for a Coldfire target. The
device entry at the end should be changed to suite your specific
parallel port and processor.
A side effect of the current I/O perm implementation is the simulation of
device nodes under the '/dev' tree. This design is copied from the Windows
version of the BDM package. The Windows build is a kind of I/O perm driver
where the GiveIO driver provides the Windows application direct access to the
parallel port rather than the ioperm system call. The simulation of BDM device
nodes under the '/dev' directory is used to keep the documentation consisent,
and to allow GDB scripts or BDM programs a common way to operate on different
platforms. The simulation means you will not find device nodes under a '/dev'
tree. This can be confusing for experienced Unix users accustomed to finding
device nodes in the '/dev' directory.
The I/O perm interface has about the same performance as the kernel
module. This is based on limited testing. The kernel module should be a little
faster for most block read/write operations. This is mostly due to the kernel
being blocked while the bit bashing occurs. If you perform a large number of
small BDM requests the performance will about the same for the ioperm direct
accesses and the kernel driver.
The Library
===========
The library provides a higher level interface to the driver without requiring
you to make low level Linux driver calls.
The library interface consists of two parts:
1) The driver interface, and
2) The remote protocol.
The driver interface make Unix driver calls via the open, close, read, write
and ioctl system calls.
The library also contains the remote protocol that talks to the BDM
server. This protocol is not the GDB remote protocol. It operates at a much
lower level than the GDB remote protocol and is designed to support a server
operating from xinetd or inetd. It also allows flash programming tools built
with the BDM library to work remotely.
The library does not contain the download support anymore. The need to contain
a specific BFD header file is broken. The GDB patch contains the code to
perform a download to target.
Windows 9x,NT,2000
==================
The library will build the driver in one pass. There is no driver needed for
Windows 9x. This should allow GDB to be built. The Cygwin or MinGW packages are
needed to build the library.
I have tested the package on Windows 98, Windows 2000 and Windows XP using
MinGW. This is cross-compiled from Linux and also compiled under MinGW on
Windows XP.
Cygwin should build and work, how-ever at the time of updating this file I
could get Cygwin installed and working to test.
Setting the minor device number
===============================
The minor device number (the second number in the mknod command) specifies
the parallel port to which the BDM interface is connected and the type of
the target CPU. The least signficant two bits of the minor device
number specify the parallel port and the remaining bits specify the target
CPU type:
7 6 5 4 3 2 1 0
+----+----+----+----+----+----+----+----+
| | | | | | | | |
+----+----+----+----+----+----+----+----+
\ / \ /
\ / \ /
\ / \ /
------------+----------- -+-
| |
| |
| +-- These two bits select the parallel
| port to which the BDM interface is
| connected: 00 - LPT1
| 01 - LPT2
| 10 - LPT3
|
+-- These six bits select the target CPU type:
000000 - CPU32+ (PD adaptor)
000001 - Coldfire
000010 - CPU32+ (ICD adaptor)
Examples
========
1. Target processor is a Motorola MC68360 (CPU32+) connected to LPT1.
Minor device number is 0.
2. Target processor is a Motorola MC68360 (CPU32+) connected to LPT2.
Minor device number is 1.
3. Target processor is a Motorola MC5206(e) or MCF5307 (Coldfire) connected
to LPT1. Minor device number is 4.

M68K BDM GDB Server
Chris Johns
3 Nov 2007
The 'gdbserver' directory contains a GDB Remote protocol server which provides
BDM support for GDB for a range of Coldfire and CPU32 processors. The server
called 'm68k-bdm-gdbserver' will have been installed when you installed the
M68K BDM package. Make sure the installed server executable's path is in your
environment's path variable.
The BDM GDB server support Linux and Windows using GDB's socket or pipe
interfaces. The socket interface is the standard way GDB talks to a GDB remote
server. The pipe mode is also supported. With the pipe mode GDB spawns the BDM
GDB server and pipe the remote protocol to the new process.
The BDM GDB Server support the BDM library's direct or remote protocol mode of
operation. If you use the BDM library remote protocol the actual hardware will
be 2 processes away from GDB.
The GDB with the BDM GDB Server will break existing GDB scripts. All the
features that the patched version had have been carried over to the BDM GDB
Server with the added advantage of no patch to maintain plus a means to add
support for new Coldfire processors simply with out the need to upgrade GDB.
GDB Patched verses GDB Remote
The old patched GDB and the newer GDB using the remote protocol will break
existing BDM GDB scripts. All the features present in the patched GDB are
present how-ever the commands to access the features have changed. There was
no way to avoid this.
The BDM GDB Server using a remote GDB has many advantages. The advantages are:
- No need to patch GDB.
- BDM fixes and updates with out the need to update GDB.
- Simpler means of adding support for new Coldfire processors.
The hardware break and watch points are supported.
The registers shown by the standard 'info reg' command is now restricted to
registers that are in normal use with-in a program. For example the 5235
processor shows:

The special BDM command are available. These are accessed using the GDB
'monitor' command. To get a list of available commands connect to the target
then issue 'monitor bdm-help'.
Note: At this point in time some commands are missing. They will be added.
Building GDB
The BDM GDB Server requires GDB 6.7 or later built for a m68k-elf or similar
target. The standard FSF sources are the only sources the BDM GDB Server is
tested with. You do not need to patch GDB but you will need to insure the
'expat' XML library is installed and GDB's configure script detecteds it
correctly. Build and install GDB the normal way. For example:
$ tar jxf gdb-6.7.1.tar.bz2
$ mkdir localhost
$ cd localhost
$ ../gdb-6.7.1/configure
$ make all install
Connecting with GDB
Connect your pod to the PC and to your target hardware then power on the
hardware. This example session is with the Axman 5235 board and using the
remote target's pipe interface.
Test you BDM hardware and software configuration by running one of the test
programs in the M68K BDM package.
Start GDB and obtain the standard GDB prompt.

(gdb)
The 'target remote |' command tells GDB to use the remote protocol via the
pipe interface. GDB will then use the remainder of the command line to invoke
the BDM GDB Server. The command line used is the simplest one that can be
used. It is:
m68k-bdm-gdbserver pipe /dev/bdmcf0
The 'm68k-bdm-gdbserver' is required to be in your environment's path. You can also
use a full path. The first parameter is the type of communications the GDB
server is to use. In this case if the 'pipe' interface. It could be a
socket and we will cover this later.
The BDM GDB Server can accept other command line options. They are:
m68k-bdm-gdbserver -vVhDd -t <time> <device>
-v Verbose. More than one the more verbose.
-V Version.
-h This help.
-D Driver debug level. More than one for more debug.
-d BDM Library debug level. More than one for more debug.
-t time Delay timing for the parallel ports.
device The device to connect to such as /dev/bdmcf0.
These options are mostly development and testing options. The following steps

This help message.
bdm-debug <level>
Set the M68K BDM debug level.
bdm-lib-debug <level>
Set the BDM library debug level.
bdm-driver-debug <level>
Set the BDM driver debug level. This may result in a
remote BDm server logging to syslog if this is enabled.
bdm-ctl-get <reg>
Get the control register where <reg> is a register value
supported by the target. For example: bdm-ctl-get 0x801
will return the VBR register for most Coldfire processors.
bdm-ctl-set <reg <value>>
Set the control reigster where <reg> is a register value
supported by the target. For example: bdm-ctl-set 0x801 0
bdm-dbg-get <reg>
Get the debug register where <reg> is a register value
supported by the target. For example: bdm-dbg-get 0x1
will return the XCSR register on Coldfire with Debug B+.
bdm-dbg-set <reg> <value>
Set the debug reigster where <reg> is a register value
supported by the target. For example: bdm-dbg-set 0x1 0
To get the VBR register you enter:
(gdb) monitor bdm-ctl-get 0x801
m68k-bdm: control reg: 0x801 = 1016 (0x3f8)
To set the VBR register you enter:

Insight Support
Chris Johns <ccj@acm.org>, 3rd Feb 2001.
Support has been added to allow Insight to run. The GDB backend and
driver are working, how-ever the dialog box for target connection
could do with more work. You can make connections, set break points,
but I have not done any real debugging. The reason is I have been
testing on Win9x and do not have any compilers setup. I also only ran
Insight from a Cygwin bash prompt.
To build Insight, first apply the gdb patch to the Insight
sources. This should apply cleanly. Then apply the Insight patch. The
Insight patch add BDM support to the target dialog box. Insight is
built the same way as GDB so the notes in the main README can be
followed. Just apply two patches instead of the one.
You need to have a GDB init file which is loaded when you start
Insight. This is the standard GDB script for booting your
processor. It must contain a GDB command `setup-and-load'. The target
dialog box should default to this, but more on the dialog box setup
later. You can find an example for the Coldfire processor in :
gdbScripts/sfp.insight
The command `setup-and-load' command must configure enough of the
processor so RAM is working and the code can be downloaded. You should
also download the code using the load command and set the program
counter.
I found on the Win9x that I could not get Insight to automatically
load a command file. On Unix having a file called `.gdbinit' in the
directory you start GDB works. The documentation for GDB states a file
`gdb.ini' should work on Windows. It did not seem to work for me so I
specified the command file to load on the command line. I suppose this
can be hidden in a Windows shortcut. The command on Win9x is :
/insight-5.0-m68-bdm-elf/bin/m68k-bdm-elf --command=sfp.insight sfp.elf
The Target Selection dialog box has two entries for BDM, BDM/Direct
and BDM/TCP.
Using BDM/Direct.
This target is used when the pod is directly connected to the machine
you are running Insight on. Enter into the Device field the BDM device
your pod is connected to, eg. /dev/bdmcf0. The Port field is present,
and I do not know how to remove it so just ignore it.
Using BDM/TCP.
This target is used when the pod is remote from the computer running
Insight. Entry into the Hostname the remote machine's name or IP
address. In the Port field enter the BDM device, eg. /dev/bdmcf0.
The remainder of the dialog box fields should be set in the following
manner :
Set breakpoint at `main' : Do not care, your choice.
Set breakpoint at `exit' : Do not care, your choice.
Set breakpoint at [ ] : Do not care, your choice.
Display Download Dialog : Off, not checked.
More Options :
Attach to Target : On, checked.
Download Program : Off, not checked.
Run Program : Off, not checked.
Continue from Last Stop : Off, not checked. Not sure what this
one is.
Command to issue after attaching : setup-and-load
Please send me feed back on using Insight as I have no real data of
how well it is being used.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

* therefore it contains prototypes of usermode functions
*
* based on code from and using (roughly) the same API as the
*
* Linux Device Driver for Public Domain BDM Interface

/* the interface of the kernel mode driver as of June 10th, 1997
*
* there are a number of ioctl's for all non-speed-critial bdm operations
* these operations allow to reset, restart, stop, step and run the chip,
* to exchange data with the bdm interface, and to set the clocking speed
* and debug-level.
*
* the download of code and the reading back of memory are considered
* speed critical, due to the fact that download times should be minimized
* therefore these two operations are supported by the BDM fill and dump
* commands. these commands are issued automatically by read and write
* system calls on the bdm driver

/* File: bdmops.c (BDM Operations)
* Purpose:
* Author: Rolf Fiedler
* Created:
*
* Initials:
* BCW - Brett Wuth
* @#[ContactWuth:
* Phone: +1 403 627-2460
* E-mail: support@castrov.cuug.ab.ca, wuth@acm.org]
*
* this is an abstraction layer to have a general target programming interface
* so the programmer doesn't have to bother with motorola's bdm commands.
*
* applications only include bdmops.h and call the functions below
*
* HISTORY:
* $Log: bdmops.c,v $
* Revision 1.2 2005/10/24 01:37:25 cjohns
* Fixed includes for building in Windows with MinGW.
*
* Revision 1.1 2003/12/29 22:18:49 codewiz
* Move tools/bdm_abstraction to m68k/bdmabstraction and autoconfiscate.
*
* Revision 1.2 2003/07/04 22:33:01 codewiz
* Applied SST block-erase patch.
*
* Revision 1.1 2003/06/03 15:42:04 codewiz
* Import userland tools from bdm-fiedler
*
* Revision 1.6 2000/09/19 00:28:29 wuth
* cleanly use Fiedler's bdm driver; bdm_mon detects flash errors
*
* Revision 1.5 2000/07/25 13:51:09 wuth
* Working sector erase. Better error reports.
*
* Revision 1.4 2000/04/20 04:56:23 wuth
* GPL. Abstract flash interface.
*
* Revision 1.3 2000/03/28 20:24:41 wuth
* Break out flash code into separate executable. Make run under Chris Johns BDM driver.
*
* Revision 1.2 1999/07/05 22:09:50 wuth
* Abort if can't sync BDM. Work with Am29F800 flash.
* @#[BasedOnTemplate: template.c version 2]

dnl @synopsis AX_CFLAGS_WARN_ALL [(shellvar)]
dnl
dnl Try to find a compiler option that enables most reasonable warnings.
dnl This macro is directly derived from VL_PROG_CC_WARNINGS which is
dnl split up into two AX_CFLAGS_WARN_ALL and AX_CFLAGS_WARN_ALL_ANSI
dnl
dnl For the GNU CC compiler it will be -Wall (and -ansi -pedantic)
dnl The result is added to the shellvar being CFLAGS by default.
dnl
dnl Currently this macro knows about GCC, Solaris C compiler,
dnl Digital Unix C compiler, C for AIX Compiler, HP-UX C compiler,
dnl IRIX C compiler, NEC SX-5 (Super-UX 10) C compiler, and Cray J90
dnl (Unicos 10.0.0.8) C compiler.

dnl implementation tactics:
dnl the for-argument contains a list of options. The first part of
dnl these does only exist to detect the compiler - usually it is
dnl a global option to enable -ansi or -extrawarnings. All other
dnl compilers will fail about it. That was needed since a lot of
dnl compilers will give false positives for some option-syntax
dnl like -Woption or -Xoption as they think of it is a pass-through
dnl to later compile stages or something. The "%" is used as a
dnl delimimiter. A non-option comment can be given after "%%" marks.

## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

2004-04-24 Bernardo Innocenti <bernie@develer.com>
* bdm.c: Fix CPU32 with ICD cable. Contributed by Aaron J. Grier
<aaron@frye.com>.
2004-04-18 Bernardo Innocenti <bernie@develer.com>
* openbsd/openbsd-bdm.c: Add OpenBSD driver derived from the FreeBSD
driver by an unknown author. Contributed by Aaron J. Grier
<aaron@frye.com>.
2001-12-12 Chris Johns <cjohns@ybertec.com.au>
* bdm.c: ICD step fix from Thomas Andrews (tandrews@mindspring.co.za).
2001-04-15 Chris Johns <cjohns@cybertec.com.au>
* bdm.c: Merged Keith Outwater performance changes into the driver.
2000-11-15 Chris Johns <ccj@acm.org>
* bdm.h:
The driver ver, cpu type and if type ioctls were the wrong size.
* bdm.h: New version.
* bdm.c: Changes to support FreeBSD's memcpy in kernel type operations.
Fixed a bug with return of error codes in the ioctl handler.
2000-09-02 Chris Johns <ccj@acm.org>
* bdm.c: ICD fixes from Alexander Aganichev <aaganichev@hypercom.com>.
* bdm.h: New version.
Fixed ICD spelling. Patch from Alexander Aganichev <aaganichev@hypercom.com>.
2000-08-31 Chris Johns <ccj@acm.org>
* bdm.h: New version.
22000-08-03 Chris Johns <ccj@acm.org>
* bdm.h: New minor version number.
* bdm.c:
Changed the CF ctrl port init value to 0x00. This value is correct.
Merged an IDC patch from Adam Kropelin <akropel1@rochester.rr.com>.
2000-06-27 Chris Johns <ccj@acm.org>
* bdm.c: Changed the control register default value to 0x0f which
allowed the driver to work on a DELL 500MHz Pentium III
machine.
2000-06-25 Chris Johns <ccj@acm.org>
* bdm.h: New version for the CF long reset.
* bdm.c:
Slowed the reset down on the Coldfire. The PLL needs time to up.
2000-05-31 Chris Johns <ccj@acm.org>
* bdm.c, bdm.h: Support for IDC added.
2000-05-27 Chris Johns <ccj@acm.org>
* bdm.c: Change all bdm* functions to bdmDev* to stop clashes
Win9x builds.
2000-05-18 Chris Johns <ccj@acm.org>
* bdm.h: Error bits as shifted values.
New version.
2000-05-17 Chris Johns <ccj@acm.org>
* bdm.c: Moved Coldfire variables in struct BDM for multi port support.
Added Coldfire debug module version detection and then
selection of PST support based on it. Ver B uses PST (5307).
Longer reset delays.
Removed setting the DSI signal to 0 on each bit.
Added support to detect false halt conditions by attempting
to read the PC twice. If you can the target has halted.
The cache is invalidated only if it is enabled.
Debug trace clean ups.
2000-03-30 Chris Johns <ccj@acm.org>
* bdm.h: Added the timeout error code. This is used by the remote
interface.
* bdm.c: Changed the delay in the hardware init for the CPU32.
2000-03-30 Chris Johns <ccj@acm.org>
* Makefile: Added the USE_PST support. Moved to clean OS structure.
* linux-bdm.c: New file.
12000-03-30 Chris Johns <ccj@acm.org>
* bdm.h: Added the timeout error code. This is used by the remote
interface.
* bdm.c: Changed the delay in the hardware init for the CPU32.
1999-10-23 Chris Johns <ccj@acm.org>
* bdm.c:
Remved the Linux specific parts to allow easier OS integration.
* bdm.h: Merged in the SCO changes.
1999-05-25 source <ccj@acm.org>
* Makefile:
It seems that depmod complains about unresolved symbols even
when the driver loads and works properly. I don't know what's
changed in Linux to cause this, but for now just get rid of
the depmod.
1999-03-18 Chris Johns <ccj@acm.org>
* bdm.c: Add support for 2.2.xx kernels.
Fri Jan 15 05:43:55 1999 Chris Johns <ccj@acm.org>
* bdm.c:
Added Coldfire support to invalidate the cache when get status detects
a change of state from running to stopped, or when go or step commands
are issued.
Sat Jan 9 03:04:03 1999 Chris Johns <ccj@acm.org>
* bdm.c: Remove the `sti()' calls in the `bdm_sleep' function.
Tue Jan 5 07:39:40 1999 Chris Johns <ccj@acm.org>
* bdm.h, bdm.c: Merged David Fiddes 5307 bkpt signal hold patch.
Sat Dec 12 04:23:28 1998 Chris Johns <ccj@acm.org>
* bdm.c: Fixed the region control logic in open.
Fixed printing csr.
Extended some of the timeouts in the CF driver.
Fixed some incorrect labels.
Fixed a lock up bug after a bus error.
* bdm.h: New version.
* Makefile: Fixed the modversions.
Sat Oct 31 05:06:15 1998 Chris Johns <ccj@acm.org>
* Makefile: Always over-write the installed header and lib.
* bdm.c: Fixed tabs, and forced the SR to be 16bit.
Sun Oct 18 04:38:00 1998 Chris Johns <ccj@acm.org>
* bdm.c: Added support for generating a bus if no repsonse is
always being returned from the BDM module.
Wed Oct 14 14:32:04 1998 Chris Johns <ccj@acm.org>
* bdm.c: Mask pending interrupts in single-step mode.
Fixed the status handling. It now uses the csr register. It is cached
to handle the fact the status bits are set for only one read.
Wed Oct 14 10:55:33 1998 Chris Johns <ccj@acm.org>
* bdm.c:
Added support for the Coldfire BDM and P&E interface. This has only
been tested inthe 5206.
* bdm.h: Added support for the Coldfire BDM.
* Makefile: Changed the prefix to the default of /usr.
Fri Oct 31 20:58:23 1997 eric <eric@skatter.usask.ca>
* Makefile: Fit into RTEMS distribution.
Thu Aug 21 15:38:28 1997 eric <eric@skatter.usask.ca>
* bdm.c: Fix up error on minor device check in bdm_open.
Remove erroneous comment in init_module.
Improve log messages in init_module.
Wed Jun 11 16:59:06 1997 eric <eric@skatter.usask.ca>
* bdm.c:
Removed code which sent an extra BDM_FILL_CMD for word or byte values.
Cleaned up some formatting.
Wed Feb 19 17:15:06 1997 eric <eric@skatter.usask.ca>
* bdm.c, bdm.h: Add `set debug level' ioctl.
Fri Feb 7 15:10:49 1997 eric <eric@skatter.usask.ca>
* Makefile: Add a single `prefix'.
Make directories if necessary when installing.
* bdm.c: Clean up some debugging messages.
Thu Feb 6 22:08:52 1997 eric <eric@skatter.usask.ca>
* Makefile: Add module installation to install target.
* bdm.c: Don't release ports that have been stolen from another driver.
* bdm.c:
Install driver even if I/O ports are claimed by some other driver.
I don't really like doing this, but the alternative would be to
require that the parallel port (LP) driver be unloaded before
the BDM driver could be loaded.
* bdm.c: More init_module message cleanup.
* bdm.c: Fix up init_module message.
* Makefile, bdm.c, bdm.h: Initial revision
