Dear Support Team,
I test system off mode under the following conditions:
NCS1.9.1; nRF52840-DK and nRF52-DK; added dk_button_init initialization code in the system off example.
After nRF52840-DK and or nRF52-DK burn compiled firmware, you can see the following log output:
*** Booting Zephyr OS build v2.7.99-ncs1-1 *** nrf52840dk_nrf52840 system off demo Retained data not supported Sleep 2 s Entering system off; press BUTTON1 to restart
Test method: Press button1 on the DK continuously and quickly within 2 seconds.
Result: the device gets bricked and the program freezes.
The following is my program, please help analyze the reason and give a solution, thank you for your support!
system_off.7z
Remarks: Only need to compile and burn to nRF52840-DK or nRF52-DK, press button1 continuously and quickly to reproduce.
