Hi,
I have made a circuit to control power on the raspberry Pi and its peripherals. To do so I have added to the userconfig.txt file the commands
dtoverlay=gpio-poweroff,gpiopin=22
dtoverlay=gpio-shutdown,gpio_pin=3
Driving the GPIO pin3 to low, I could switch on the power or give a shutdown command to Volumio and when the Volumio was shut down the GPIO pin 22 was driven high.
That worked well on Volumio 2.8, but when recently updated to the latest version 3.812, when the GPIO pin3 is driven low, the software does not shutdown.
Is there any way to resolve the problem?
regards
