6 years ago You are trying to open BCM16, which is not a valid pin on the imx7.d.
Looking at the device pinouts, BCM16 on the Raspberry Pi is GPIO2_IO07 on the imx7.d.
You may need to include this GPIO name as an additional parameter in the code of the AssistantActivity (Stacktrace shows AssistantActivity:310) to select the correct pin.
It may make more sense for this issue to go in the relevant repository. https://github.com/androidthings/sample-googleassistant

I'm using the AIY Assistant kit with the Pico Pro i.MX7d (instead of the Raspberry Pi.
When I compile and run I have this issue:

Any idea what can it be?
