I want to power on/off the maching by using a key to control “power en” gpio on jetson nano board. When I click the key to power off, there is a menu display on the screen with the description “Hi user, you have open files you might want to save. Would you like to…” even if I don’t open any App or file. And it will auto power off the system in 10s if I do nothing.
Could you please help to slove my problems:
- Which gnome service or API does power_en gpio trigger? Can I modiy the description on the meun and disable the auto power down function?
2.I find that power en gpio in /sys/kernel/debug/gpio is 189, but on carry board schematics the connector power en pin is 237. How to match connector pins with CPU pins?
