Hi,
I'm building a safe shutdown board, which, on power removal, holds up the power to the RPi with a LiPo, requests the RPi to shutdown, waits for shutdown complete, then removes the RPi power. For the shutdown complete, I'm using the dtoverlay gpio-poweroff with no problem.
On previous iterations, I've used the dtoverlay gpio-shutdown for the shutdown request, but this has changed to require a double fall-rise to shutdown. I can monitor the GPIO pin and request the shutdown from my program, but the dtoverlay gpio-shutdown solution seems neater.
So, is there a configuration parameter on gpio-shutdown to alter it to a single fall to 0V, to request a shutdown?
The applications would mainly be RPi's with displays, but no keyboard and mouse.
Thanks
