verifying the c program

[lightofspace]

Hello,

I have a question concerns verification of C program in Embedded System, I wrote a C program with memory resource being shard between two interrupt handler (a kind if preemtive processing), but I am getting some problem in the implementation....following the error is very hard to by analyzed, so does someone know how to verify C program, and knows how it is working (its lfow control)?

All thanks
Ahmad

You should use a hardware debugger (like MAJIC or Multi-ICE) to look at the details of program execution and control like pointer tables, heap, stack etc.

If you cannot afford a debugger, you can choose an I/O line of the micro-controller as a signal. Activate this line from some place in your code will show you with certainity that the processor has reached that line of code.

If you can spare more than one I/O lines, you can track the execution path with more sophistication.

Emulators is the solution for this... somewhat chep but not very cheap.
