Is nrf_power_resetreas_get() still the way to read the boot reason in NCS?

[AndreKR]

From various pages I copied together this code to read the reset reason:

#include <hal/nrf_power.h>
uint32_t reset_reason = nrf_power_resetreas_get(NRF_POWER));
nrf_power_resetreas_clear(NRF_POWER, reset_reason);

However, I believe most of those pages were for nRF5 SDK. (It's not always clear.)

Is this still the recommended solution in nRF Connect SDK? Specifically, I want to detect a watchdog reset.

Hi Andre,

You can use the nrf_power_resetreas_get(NRF_POWER); to get the reset reason. Also, you can directly read the RESETREAS register for the reason.

Quick followup question in general... how does direct register access work in NCS, is there a register map in the board files or do I literally copy the address from the particular chip docs?

You can read the register using it's address mentioned in the product specification.
