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.

|
|
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.
