Program Exception in MPC8572

Hi,

We are facing a program exceptionat at a critical stage of our project.

The details are as follows:

 

CW debugger USB Tap

OS : VxWorks

Board : MPC8572AMC

 

When i go to the exception address pointed by the CIA i can see that the opcode is all zero and debugger displays it as "Invalid Opcode". This address changes for every time.

 

Since this project is a integrated from several modules, we are not in a position to do code review.

 

Is there any tip or trick to detect who is corrupting the program memory?

 

I tried setting watchpoints but CW aborts.

 

I would appreciate any early reply on this.

 

Thanks,

Sarava
