I’m trying to debug suspend mode on Jetson Nano on our custom board. When I tried to entering suspend into memory
sudo systemctrl suspend
Now screen disappear as expected but get back to Ubuntu login page soon without doing anything.
I check the wake source
sudo cat /sys/kernel/debug/wakeup_sources
I found gpio-key changes. So I check my device tree setting, there are 2 gpio-key settings
- power button
- recovery button
But these push button are left it unchanged, it shouldn’t be wakeup source after suspend.
Is there any way to debug this ?
