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! :)

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?
