U-Boot config from https://github.com/radxa/u-boot/commit/5202c429714e34dcaeb6ea2a76822fb8447e1409 Depends on https://github.com/armbian/linux-rockchip/pull/231 (which, as of writing, is not merged) How Has This Been Tested? [x] Boots (from microSD) [x] USB serial via debug port works (see note) [x] LAN port works (RK3528 Ethernet) [x] WAN port works (RTL8168 Ethernet) [x] Debug USB-C port works (can run USB gadgets) [x] USB-A port works (can use USB devices) [x] User button works (via /dev/input/event0) [x] LED control works (via /sys/class/leds) [x] eMMC access works Not tested: RKMPP (did not find any tools that worked with the 6.1 kernel, only 5.10) eMMC boot (should work, though flashing tools are unreliable) Note that USB serial is unreliable, likely due to the CH340B USB serial chip on the board not being able to handle the RK3528's baudrate. Changing the baudrate can only be done by editing the device tree (as stty will not affect it).
