Hi,

There is a NRF_POWER->RESETREAS register you can use to check the reset reason.

To execute a soft reset you can run NVIC_SystemReset() from the application at any time, which will set the soft reset bit in RESETREAS on startup. If you write to NRF_POWER->GPREGRET and NRF_POWER->GPREGRET2 (each can contain 8bits) before execute soft reset, then you can check on startup the GPREGRET registers to find for instance which code you want to run on startup.

Best regards,
Kenneth
