Orange Pi One power switch in next kernel Ubuntu

[IgorS]

Please help, what I am missing?

With legacy kernel installed acpid and pressing power button on OpiOne gives me events (monitoring with acpi_listen).

Same thing not working with next kernel 4.14.18.

Do anybody have solution?

Since nothing on the PCB suggests that this button is a power button (and since suspend/resume and wakeup after shutdown is not currently possible) by default it has a different button code: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/arch/arm/boot/dts/sun8i-h3-orangepi-one.dts#n96

 

It can be changed to KEY_POWER with a custom Device Tree overlay.

Thank you very much for answer... But I really  don't know how to write such Device Tree overlay. Can you help me with this?

I am looking to example:

https://github.com/armbian/sunxi-DT-overlays/blob/master/examples/gpio-button.dts

Could I only change pin number in this example?

No since it will conflict with the existing button definition unless you remove it.

 

The DT overlay should probably look like this:

/dts-v1/;
/plugin/;

/ {
  fragment@0 {
    target-path = "/r_gpio_keys/sw4";
    __overlay__ {
      linux,code = <116>;
    };
  };
};

};

Thanks a lot, I'll try.

Compiled and activated overlay, but still nothing from acpi_listen

Can anybody help, please, I can't figure out how to fix this to work. Despite loaded overlay which change emited code to KEY_POWER on button press, there is no event created in /sys, I think that still something missing. This is beyond of my knowledge so please help.

I have the same problem. I can not activate the Power button.
I used the following commands:
apt-get install acpid
nano /etc/acpi/events/button_power
write code
event=button/power
action=/sbin/shutdown -h now
and
/etc/init.d/acpid restart
Help me. I'm new to linux
