Please describe your issue below:

I try to make robot on khadas platform. On my robot I have master power button. This button connect and disconnect USB C PD line to battery. Also I use Juice v12 Board for safety power off and emergency power. I need to switch on khadas when master button is on and I have power on USB C PD line. Also i need correctly switch off khadas (like shutdown in terminal) when master button is off and I have not power on USB C PD line.

How it work now.

Power no

Khadas is setup WON option. Some device in robot send WON command to khadas every minute. Khadas switch on by WON command.

Power off

I wrote script in python. this script look at /sys/class/power_supply/bq25700-charger/online and write to terminal shutdown now

How can I make my system more correct? I will to switch on and off by USB C PD. I need switch off regularly like shutdown now.

So what issues you have now ?

#3

This would be the use cases which need your help in implementing them:

  1. The Edge-V is powered off and the battery is connected to it via the Juice Board.
    Edge-V needs to be enabled when the USB-C PD power supply is connected.

  2. Edge-V is powered on and connected to the battery via the Juice Board.
    We need a soft shutdown as in shutdown -h now when switching off the USB-C PD power supply.
