How to enable hardfault_handler in SDK12.3.0

[nordicdev]

Hi, I am using sdk 12.3.0 sd130v2. I have the hardfault_implementation.c included in the project. But I am not able to keep breakpoint anywhere in that file. I have made HARDFAULT_HANDLER_ENABLED 1 in sdk_config.h and included 'HARDFAULT_HANDLER_ENABLED' in project options defines. Still no luck. In other words, how to debug hardfault handler error in sdk 12.3.0?

Could you check the Error log "Hardfault PC: " to see where were the last position of the PC before the hardfault. Or you can look for the value of ((HardFault_stack_t *)p_stack_address)->pc directly when debugging.

Then you can track back to the line of code causing the hardfault in the disassembly window.
