The Serial setting is 115200-8-N-1. The board has a populated right angle 1x4 0.1" pinheader. The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND. Odd stuff: - uboot does not support lzma compression, but gzip'd uImage/DTB work. - uboot claims to support FIT, but fails to pass the DTB to the kernel. Appending the dtb after the kernel image works. - RGB-controller is supported through an external userspace program. - The ubi partition contains a "board-config" volume. It stores the MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical). - SoC's temperature sensor always reports that it is on fire. This causes the system to immediately shutdown! Looking at reported "418 degree Celsius" suggests that this sensor is not working.
