    No problem, you'll catch it the next time.

    NULL or invalid pointers are a classic cause of Hard Faults, and the address you were pointing to looked just fine. So I looked at the next most likely reason.

    Was Atollic pointing you at this address, or do you have some fault handler code, like Joseph Yiu's example?

    Yes, the problem was that!

    There was an uninitialized pointer :(

    And it wasn't signaled by the IDE!! :( :(

    I did a lot of noise for a stupid problem... Sorry!

    Thaks Clive1 for the illuminating hint! :)

    I.
