Hi Nesrine,

Seems icf file is ok, did the code try to write some register in which clock gate is not on? or did the code write to some place in the flash? You may check the following registers when the hardfault happens.

Have a great day,
Kan

I checked registers the problem is that The FPU is disabled from reset so You must enable it before you can use any floating-point

instructions.

thank you Kan
