you cannot use fds in hardfault handler. Hardfault is higher priority exception than the SWI interrupts (BLE event handling) which is needed for the fds to work properly when using softdevice.

I don't have a connection to the device all the time so I need to save this info in flash. But when I use fds library in HardFault_c_handler I am not able to save them. But when I use the fds library, I don't get any errors either.

Normally in the HardFault_c_handler default implementation you should have this deducible when debugging or are thrown out to the selected logger backend.

Hi, Can you explain how you log the error reason and program counter? Do you log them into the flash? If the answer is yes, Which flash did you use?

most likely it is invalid or garbage value popped for a corrupted stack. First thing i would check to see if there was enough RAM space for the application to run.
