Code Warrior/ S12X question

MIkeX — Fri, 17 Mar 2006 23:24:27 GMT

Hello all,

I have a error message on the debugger screen that says IIEGAL_BP. I have not been able to get around it and for that matter I don't know whats causing it. Any ideas.

Thanks

Mike

This is usually an indication that your code is running away.

When it stops and gives this error, the program counter will probably not be in the area of memory where your program is placed.

Assuming you are compiling or assembling code and downloading into the part then the most likely cause of this problem is an interrupt that is not trapped or a table jump that doesn't go where you expect.

Thanks, I'll look at the vectors/interrupts. I'm also using the OSEKturbo RTOS, which has not been so friendly
