Hi,
I am looking at how to know that shutdown has completed by looking at a gpio. I have looked at the dtoverlay for gpio-poweroff and it works minus on gpio 2 with active low, it goes low for 100ms then high for 100ms, then low again (not sure which low to look at).
So I noticed that the pi if gpio-poweroff is used keeps the gpio state that is set from a program until after shutoff, so I was curious when this change actually happens.
Any insight here is much appreciated, thanks!
