I’ve put the patchbox os on my SD card and I can get it to boot. Once I get to the point where it wants me to enter a user and password (https://blokas.io/patchbox-os/docs/GettingStarted/), the device is unresponsive. I assume this is because my keyboard isn’t being recognized (it’s a standard hp keyboard). So I turn the device off, unplug the keyboard and try again, but the thing now won’t boot at all. I have to reinstall the entire OS to get it to boot again because of what seems to be keyboard problem, that’s very frustrating.
I’ll keep debugging and update here if I learn anything else.
