Re: interrupts +pb0555 +codewarrior

I am using CW for mpc5xx.

The initial error was at address 0x0500 
http://people.tamu.edu/~leblanc/forums/interrupts/intialerror.jpg
but once I uncheck exception handling for External interrupts
0x02000000,  I get the machine check error.


I agree that the problem lies in linker command file rom version
(.lcf), eppc_exception.asm, and/or interrupt.c


can anyone provide these 3 files for the pb0555 board.  And a user
defined c interrupt handler? (maybe even using #pragma options for
codewarrior?) 


I've been stuck on this problem for about a month (i'm on my own). 
Any help is much appreciated.  Again my current project can be
downloaded from: http://people.tamu.edu/~leblanc/forums/interrupts/


Thanks,

Leblanc Meneses
