I haven't tried just applying the minimal patches and/or configuration on top of Guix's linux-libre, but that seems like a logical next step... > I did manage to get the rockchip.usb_uart with a hacked up USB cable to > produce a serial console for debugging and actually seeing the kernel > logs rather than them scrolling pass the screen only to give a kernel > panic. > > (kernel-arguments '("console=ttyS2,115200" "rockchip.usb_uart")) To be clear, this feature doesn't actually make a serial console over USB, it somehow "rewires" one of the USB ports to have a ground, rx and tx serial-ttl pinout. So you pretty much need a custom USB-A plug and solder/crimp the bare wires to a serial-ttl adapter.
