// Memory Configuration File
|
|
//
|
|
// Description:
|
|
// A memory configuration file contains commands that define the legally accessible
|
|
// areas of memory for your specific board. Useful for example when the debugger
|
|
// tries to display the content of a "char *" variable, that has not yet been initialized.
|
|
// In this case the debugger may try to read from a bogus address, which could cause a
|
|
// bus error.
|
|
//
|
|
// Board:
|
|
// LogicPD COLDARI1
|
|
//
|
|
// Reference:
|
|
// MCF5475RM.pdf
