I’m a big fan of manual configuration because it gives me freedom.
I bought NanoPi R2S to learn to install any linux distribution that I want on a rockchip SBC. I was able to use dirty hacks to create idbloader.img, trust.img, and uboot.img from downstream u-boot. I compiled downstream kernel and wrote extlinux/extlinux.conf. However, it seems that I need to turn /boot(boot.img) and /(rootfs.img) into ext4 android images with make_ext4fs. I haven’t been able to boot it.
I expect Rock Pi products to be similar because they are also rockchip SBCs.
At least, it was relatively straightforward to configure raspberry pi manually.
Have I been looking in a wrong direction? Is there a simple way to configure rockchip SBCs?
