Sinil, If you are now seeing the Machine Check Exception then it is probable that Randy's tip on the codewarrior settings has worked and you are now taking the external exception, rather than the debugger. The machine check indicates that there has been some kind of memory access error, either due to the mechanisation of your exception handling code, or a real problem with the device driver code you are writing. In either case you're now probably into debugging your code rather than looking for a magic compiler switch or debugger option. When the debugger takes the machine check, look in SRR0 & SRR1 and it'll give you the Program Counter and Machine State when the exception occurred. Now we're coding .. Oh Yeah!
