How to do the log mechanism whenever wdt or hard fault happens in NRF52832?

Hi

My application with SDK11 S132 softdevice is having some unknown issues that will make wdt or hard fault handler happen. And I am trying to use the following code to access the flash memory in wdt

sd_flash_page_erase( page_num ); nrf_delay_ms(50); sd_flash_write( calib_addr, program_word, 25 ); nrf_delay_ms(50);

but it jumps to hard fault handler. How can I implement the mechanism even in hard fault, wdt, bus fault handler to store some important indicators in the flash so that I can still get the information in the next boot up?

what do you mean 'failed' - how did it fail? Either it's running your code or it's in a fault handler, there are no other options. Yes you can absolutely access the NVMC inside a WDT handler or any other handler come to that.

Got it. Thanks for your reply. After went through the datasheet in WDT chapter, the watchdog reset will be postponed with two 32.768 kHz clock cycles after the TIMEOUT event has been generated.

I wrote too many bytes more than it could process.

Hey I am having the same issue, but I couldn't understand about WDT. Can you please share your code
