i recomend using the nrf_malloc and such memory allocation functions bcz the standard malloc will eventually cause fragmentation like what happened with me.

No, he didn't. :) And I definitely do not believe the "don't use it anywhere" part.

(sorry, cannot resist the note: haven't your teacher also mentioned "don't use malloc in embedded systems - and possibly don't use it anywhere"?:)

Hi,

once more I needed to conclude that my old programming teacher was right: "Computers do not make mistakes; programmers do."

The cause of the strange behavior of malloc() was my fault, a logical error in the program. I called free() twice with the same pointer, which corrupted memory so that the next malloc() call caused the hard fault.

Sorry for taking your time.

OK, I looked in SDK...\components\libraries\hardfault\ and learned a bit. Thanks!

Can you please point me to some resource on how to do that?

Have you tired enabling the hardfault handler to see what was executing during the hardfault?
