Illegal BP MC9S12XDP

[interista]

Hello,

First of all I am sorry for the possible faults, I am not English-speaking and I hope  you will understand my problem!

I have some problems to execute  a project with CodeWarrior. As soon as I execute my project the debugger tells me "ILLegal BP" and ends code (at the red line in the following code)  while it executes Start12.c (fonction Init())

Thank you

Regards

Hello

I don't thik that is a problem with my project. I got the same message "ILLEGAL_BP" even if i create a new project.

Furthermore, the project has already worked with a similar card.

Thanks

Hello,did you solve this problem？

I have met the same problem...I can't use"start" to debug my project

Let's get some more info here. You say this setup (compiler, system, probe) works on a similar card, but not this one? How similar are these two cards? MIght one have a different derivative of the MCU? Illegal BP messages are usually a signature of a stack problem or a bogus memory access. This can happen when a derivative MCU might have its control registers or physical memory located in different sections of the memory map. If the cards have the same MCU but different vendors made the cards, the card's memory map for their peripherals might be different.
