Power Key/button on rk3399-roc-pc

suniel

Can you guys please suggest me on my requirement.

rk3399-roc-pc board has a Power Key/button. As per the schematics this
Power Key/button is connected to GPIO0_A5.

My requirement is can I use this button for board powerup (especially
in linux when we issue "poweroff" command, the board shuts down and it should power back on
after I press the Power Key/button).

For the above to happen, I think this Power Key/button be connected to
PMIC RK808-D IC, am i correct ?

In the schematics, it is not very clear as if such arrangement is
there (though it says it can be an option in
RK3399_BOX_REF_V13_20180821.pdf).

Please suggest/comment on my requirement.

Thanks

Have you checked if the RK808-D PMIC is configured to handle wake-up events from GPIO0_A5, and does the device tree include the necessary settings for Retro Bowl 25 power key wake-up in your Linux kernel configuration?

Have you tried checking the GPIO0_A5 pin status after the poweroff command? And have you checked if u-boot or the kernel supports the “wake from GPIO” function? I think these That's Not My Neighbor details may affect whether the Power button can reactivate the system after shutdown.

The power key on RK3399-ROC-PC handles boot/shutdown functions. Piso Wifi Ensure correct GPIO mapping and kernel support for proper button behavior.

On the rk3399-roc-pc running Linux, the power key/button can be configured via device tree and input-event handling for shutdown, Minecraft APK is an amazing gaming world which offers engaging suspend, or custom actions using systemd or ACPI scripts.
