Taken from the NET+OS Programmer's Guide, page 193:
> To diagnose an unexpected exception:
> 1 Put a breakpoint on customizeExceptionHandler.
> 2 When the breakpoint is reached, step into the routine until it sets customizeExceptionHandlerClearToContinue to TRUE.
> 3 Set customizeExceptionHandlerClearToContinue to 0.
> 4 Step through the routine until just before it returns.
> 5 Switch the debugger display to show assemble instructions.
> 6 Step through the code assembler instructions one at a time until the processor returns to the source of the exception.
Even though I'm using the ConnectCore 9C, I think the process will still be the same, or similar. You can find the customizeExceptionHandler in
C:\netos72\src\bsp\customize\errhndlr.c, line 320.
