How can I visualise the memory (SRAM) usage of an AVR program?

Question

I have encountered a problem in a C program running on an AVR microcontroller (ATMega328P). I believe it is due to a stack/heap collision but I\'d like to be able to confirm

Answer 1

If you can edit the code for your heap, you could pad it with a couple of extra bytes (tricky on such low resources) on each block of memory. These bytes could contain a known pattern different from the stack. This might give you a clue if it collides with the stack by seeing it appear inside the stack or vice versa.
