CAF button wakeup does sometimes not happen in ncs 2.5.0, if pressed again while powering down

[tellg]

In ncs 2.4.0, this code was executed in power_manager.c when button pressed while powering down:

            LOG_INF("Wake up when going into sleep - rebooting");

            sys_reboot(SYS_REBOOT_WARM);

In ncs 2.5.0, this does not happen, leading to no more wakeup from that button if pressed again during power down

Note: Still works OK if button not pressed again until after power down is completed

Using custom board with nRF52840

Hi tellg,

I have gotten feedback from our team. The issue is indeed with the change to use sys_poweroff(), like you have pointed out.

sys_poweroff() will put the system int power-off right in place. Therefore, additional events, such as the button presses, were not processed.

The developers have registered the issue and will work on an alternative approach. I cannot comment on when that will be available though.

Is this issue critical for you now? If yes, is there any change in NCS 2.5.0 that you need, compared to 2.4.2?

[tellg]

It is not critical, since we have 2 buttons configured for wakeup. The chance of a user pressing both buttons during shutdown in minimal. We have also speeded up our shutdown tasks, so that there is less chance for the issue to happen on our device.

But a later fix will of course be welcomed :-)

That's good to know. I will keep the ticket open and inform here when a fix is released.

Thank you for the report.
