After nrf_power_system_off is called, the function returns no return and has 600uA power current.

Hello~

The environment： Chip is nrf52820，SDK version is 17.0.2，sd  version is s112_7.2.0.

pic1:

Pic1 the APP code that I wrote for this problem. When I only burned the SD and APP.After the device went to sleep, the current  was about 0.4uA.

But if you burn SD, APP and bootloader. The device failed to go into hibernation with 600uA current. The current is the normal value without debug state.

Then I debug both cases , case1 was only burned SD+APP,   case2 was burned SD+APP+BOOTLOADER(The bootloader determines that it can be used properly).

Look at Pic2,

Case1  sd_power_system_off function in case1 returns normally and enters nrf_power_system_off to do the loop.

Case2  will stop at nrf_power_system_off  and never return.

Pic2:

I don't know how to debug anymore.

Thank you ! !

Sorry，Subject has a problem.  It should be after sd_power_system_off is called, not the nrf_power_system_off.
