Using GPIO pins

PI4B-Adapter with CB1
How to access GPIO pins? If its the same as using a raspberry pi - then how would you flash the CB1 as an MCU? and then use the onboard GPIO pins?

The OS for the CB1 doesn't support the GPIO interface currently, hopefully it will be in a future release.

Also, note the DSI & CSI ports are not supported at all when using a CB1.
