For some reason I can't edit my previous posts. Anyway, does the X728 rely on GPIO3 to wake the RPi? If I use this function will I have a problem with powering up the RPi?

I just found this kernel option for config.txt - should I be using this on GPIO12? Name: gpio-poweroff Info: Drives a GPIO high or low on poweroff (including halt). Enabling this ove...

That's useful info - are you relying on the kernel to hold GPIO12 high until the kernel is stopped? Otherwise how do you ensure that GPIO12 does not become 0 before the filesystems have been unmoun...

Hi, Hello, our shutdown logic is as follows: when the system is in normal use, gpio12 is 3.3V, if GPIO12 will becomes 0 after the system is shut down safely, once the MCU detects that GPIO12 is 0,...
