I’ve been lately running DietPi on a handheld computer of my own construction, cobbled together from a Raspberry Pi Zero 2W, a Keebdeck, a Sharp Memory Display, a power management board from Adafruit, and a lithium polymer battery pack. It’s basically something like the SQFMI Beepy, and I’ve been wondering how easy it will be to run this system on a different SBC like a Radxa Zero 3W. It seems like it should be possible to make it have SPI and I²C on the same pins as the Raspberry Pi Zero 2W with a suitable device tree overlay, but I’ve not found a lot of documentation on how to do this on such Radxa hardware. Can anyone tell me how I can accomplish this?
