I want to make my code smart so i can know the fault code and handle it without the need to enter the infinite loop.

is it possible? because i tried but the compiler gives me code errors.

Thanks

Yes it is possible. What did you try adding and what compiler errors did you get? Typically the first few instructions of a fault code handler are in assembly language so that you can access the xPSR. Here is a good article on an M4 hardware fault handler.
