Building u-boot

As of 5/8/2024, there is no upstream support for the Tinkerboard 2 or 2 S in u-boot sources. So, the from-scratch u-boot part of this project is still a work in progress. This is also true for the older Tinkerboard -- the general approach is described in this article User:Brendlefly62/Rockchip_RK3288_Asus_Tinker_Board_S/Build-Install-U-Boot.

Meanwhile, there is official support for the Tinkerboard and community support for the Tinkerboard 2/2 S in Armbian. The procedure for building u-boot for OrangePi 5/5b is identical to that outlined at Rockchip RK3399 Asus Tinker Board 2 S/Build-Install-U-Boot (Remember to substitute "orangepi5" for the BOARD name in both runs of armbian/build's compile.sh script, instead of "tinkerboard-2"

Note the instructions for creating a more-informative boot.cmd/boot.scr u-boot script, and in the associated joetooEnv.txt, remember specify -- fdtfile==rk3588s-orangepi-5b.dtb and overlay_prefix=orangepi-5. The full file should look something like this -
