Not all of the board periperals are enabled yet, as some of them still require kernel patches to work properly. The nodes for those peripherals will be added as soon as the required patches are upstream. The following has been tested to work: - UART console - SD card - eMMC - Gigabit Ethernet - USB (internal Keyboard, Mouse, external ports) - M.2 PCIe port Co-developed-by: Lukas F.
