Debugging from flash

[Corrin Meyer]

I am using the P&E Micro flash utility (CPROGCFZ) to flash the ColdFire
on the board I am working on.  I would like to be able to debug the
running program using GDB.  The problem is that the error I am getting
is right at boot and since the USB device can't be claimed by both the
P&E Micro utility and the m68k-elf-sprite at the same time I have to
first flash it and then connect GDB to it but by that time it has
already run into the error.

 

I need to be able to tell the program to restart.  Normally I would just
do a 'load' command within GDB but that will only work when running from
RAM.  Is there anyway to restart a program that is already running in
flash?  I can't do a reset as then breakpoint set by GDB is cleared, it
needs to be a software reset issued by GDB.
