POWER unexpected reset

[huaminhtuan]

Hi everyone,

I am developing a remote control using nRF52832 chip. My prototype is currently developed in PC10040 board. The IDE is Eclipse Oxygen, and the SDK is S132 v5.0.0.

Currently, I am trying to put the system in low power mode using POWER module. I can easily power off the system by setting the register NRF_POWER->SYSTEMOFF = 0x01;. The problem is when I try to wake up the chip by pressing a button, which is configured with SENSE_LOW mechanisim, the system is unexpectedly reset countinously. I don't know where is the reason.

Could you help me please? Thanks

Hi,

Are you using the SoftDevice ? If so you should use the sd_power_system_off() function.

A reset indicates that you are running into the error handler, where the default behavior is to do a reset. You should then debug in order to find the reason for the reset. See this post about debugging.
