Re: [beagleboard] [buildroot] Enable power button in BBB
Thanks for quick response.
Im using Busybox, but i can try build with systemd tomorrow.
Is there a quick way to overwrite power off sequence using busybox to make
it work correctly?
Working power button isn't nesesery im my case.

In debian, the power button get's mapped to a KEY_POWER, and systemd
initiates shutdown..
Are you using systemd in your buildroot image? If so what version?
Pre-systemd we use to use an acpi-tool to help shutdown, it wasn't the
greatest..

Im using kernel 4.19.79
On default Debian image:
- when i press power button then the system is power off and power LED is
off
- when i run `poweroff` then system is going down and power led is OFF
On my buildroot image:
- when i press power button nothing happend
- when i run `poweroff` then system is going down and power led is still ON
How to enable full power support in buildroot image?

Szymon
