[coldfire-gnu-discuss] m68k-elf-sprite 4.2-125 crashing

[Matt Cohn]

Hi David,

I gave the tool a try, I had five sucesses before a failure, the last item to appear on the log in the failure was "Filling memory from location $10000100 to $1000011F".  Unfourtunatley that still leaves either my computer's USB to blame (although I have used multiple ports on separate controllers) or the BDM on the board itself, but it does confirm that the problem is not with GDB or the GNU/codesourcery toolchain.  I would love to try on my laptop to narrow it down, however I've been unable to get my Vista laptop to recognize the USB Multilink.  After installing the drivers, uninstalling, reinstalling, although USBDeview shows the board connected, various tools are all unable to see the USB Multilink.

I suppose I will continue to use it as-is until later this month when I'm back in school.  My professor has the same board, so I can find out exactly what's to blame.

Thank you for all your help,
--Matt
