You can try this image built by myself: https://github.com/amazingfate/armbian-rock3a-images/releases/tag/20220604-0650
I did't try the images from the official, but it should works.
What do you mean "not working"? Kernel 5.10 from qxhome is a rockchip legacy kernel for rk3588 and qxhome modified it to support rk3568. It's not a rockchip official supported branch for rk356x.
I created a pull pull request to add gpu support for radxa rock3a. Since this the first time I do this I need a maintainer to approve running workflows.
Does anybody have the permission to do this so that we can make this support merged?
