There are unfortunately no detailed instructions how to add new boards or board families to the build framework yet. This is a very extensive topic. However there are a few existing pull requests that should give clues like https://github.com/armbian/build/pull/7902/files
No, since it is community supported use Stating section for Rockchip devices in forums.
I did a quick check on your work.
- dts files which aren't upstreamed (yet) shall be added in full into the dt folder of the equivalent kernel patch directory (patch/kernel/archive/rockchip64-6.16/dt to say). You can use
code {
font-family: Consolas,"courier new";
color: crimson;
background-color: rgba(0, 0, 0, 0.2);
padding: 2px;
font-size: 105%;
}
kernel-dtb build command to extract such a full tree.
- this also avoids my 2nd concern which is modifying the existing orangepi-5.dtsi and disabling nodes which where later re-added with another patch.
- if possible try to bump to latest mainline u-boot, so either v2025.04 or wait a bit longer for v2025.07 which is currently RC.
