RE: interrupts +pb0555 +codewarrior

Something confuses me - "unchecked exception handling for External at
0x02000000".  The external interrupt is at 0x0500, so where are you
getting 0x02000000 from?  Obvious question - you are using CW for MPC5xx
aren't you?
 
If you are getting a machine check exception, it often means you are
trying to access data or instructions from an incorrect address and
could be caused by incorrect linker file, ext memory not initialised or
incorrect exception vectors.

Subject: [MPC500] interrupts +pb0555 +codewarrior



Hello I am trying to get interrupts working on axiom pb0555 board using
metrowerks codewarrior.

The zipped project file located here:
http://people.tamu.edu/~leblanc/forums/interrupts/
<http://people.tamu.edu/~leblanc/forums/interrupts/> 

is the closest thing generating anything that resembles an exception.

PowerPC Exception: Machine Check Exception 0x0200

My MAIN goal is to setup a C interrupt handler (catch all) which
branches to
specific handlers.

Again I'm using metrowerks codewarrior on pb0555. 

Also since i used the project created by codewarrior: which includes the
following files + more: 

linker command file rom version (.lcf) note: [??what happened to
linker for debug??]

eppc_exception.asm

interrupt.c

I would like to get this project properly configured...delete files and
make
necessary changes ect.

Lastly if interrupts do work for me.. is it possible to set breakpoint
inside interrupts?

I have a slackware guru on my team so if you have free command line
tools
with the command to do this 

which removes all the crapy template files generated by codewarrior;
I'll
accept that solution also.

References:

1) I've already read AN2109 written for (diab compiler) 

2) Countless threads complaining of this same problem.

3) Inside debug version settings in codewarrior uncheck exception
handling
for External 0x02000000
