Hi there,
I would like to use GPIO3 to (re-)start my Pi3 after a shutdown. According to this guide you just need to short pins 5 (GPIO3) & 6 GND (for a short time).
But according to the documentation here, the AMP2 uses GPIO2-3 (pins 3 and 5) for products configuration.
Is it safe to quickly short GPIO3 to GND when the Pi is in halt state?
Regards,
Chris
In general it might work. However, it is possible that the Amp won't be discovered during boot. You can try, but I can't guarantee it will work. Pulling GPIO 2 and/or 3 to GND won't damage the Amp.

Thanks for the quick reply, Daniel.
I tested it and it's working perfectly. Also no problems with the discovery of the Amp (it's the falling edge that wakes up the PI).
By the way I'm quite happy with the sound quality!
Regards,
Chris
