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

Hi tellg,

I have asked about this behavior change internally and will update you when I get any feedback. Do you mind sharing why you need the wakeup button to work before powering down is completed?

I don't need wakeup to work at that point, but if buttonpress happens while powering down, then that button cannot wakeup the system anymore (device reset seems to be needed to fix this). I think the referenced code took care of that situation in ncs 2.4.0, but power down was modified in ncs 2.5.0 to use sys_poweroff, ref https://github.com/nrfconnect/sdk-nrf/commit/b6aa1ab2aae94c5e266c73ef5930d6893cb971d3

Ah I see. That is a problem. I will follow-up with you as soon as I get any information.
