How can I read RESETREAS register using a softdevice?

[ndarkness]

Hello,

I would like to know how I can identify the reason for a reset in my device, I have read about the register NRF_POWER->RESETREAS but I don't know how to check it since I am using a softdevice.

I have read as well this post but I couldn't capture the reset reason with it, thus I am turning to the NRF_POWER->RESETREAS register.

Any hints?

Thanks in advance

Simply read that register right after your FW boots way before you enable SD. No conflict at that time, you can freely read the value (I actually believe you can read it like that even when SD is active but it doesn't matter).

Thanks again! I have GPIO and GPIOTE enable. I have some GPIO's set as ouput not input, GPIOTE is not configured to sense any pin (yet), I send my chip to sleep and I have connected an ACC to my board through and arduino board/shield on pins

 #define ADXL362_SCK_PIN   14  //D3
  #define ADXL362_MOSI_PIN  15  //D4
  #define ADXL362_MISO_PIN  16  //D5
  #define ADXL362_CS_PIN    18  //D7
  #define ADXL362_INT1      20  //D9

So I think I am reading well RESETREAS register ;)
