Validating Code Memory

Hi,
I'm validating if the codes in code memory is corrupted by calculating the check sum. So what is the method to access the last location where the code ends in code memory. How do I determine this location during run time. Please update me on this mail Id: akshayskumar@gmail.com

  • OK, I know, that some medical standards require useless checks and do not require useful checks (remember the failing shield that killed several).

    When such requirements exist, of corse, you have no choice.

    so, remember that all erased memory read FF and just checksum to the end.

    most important after implementing required safeties, go through everything and say "what happens if this fails", "what happens if that fails"...

    It does not help to test the uC before you start if someone get harmed if it fails after the start.
