Hallo, you can fill the stackrange in your memory with a pattern like 0xaa55 before you run your program. After you run your program for a defined time, you...
Another method would be to use a spare timer interrupt vector running at a higher rate than any other timers for debug that will peek at the stack pointer and...

We have been using a DC-DC converter that supplied a power-ok signal when the 5v output was stable, this was used to control the 9s12xDP512 reset line. We now...
