I was able to run Armbian on DQ08.
You need to use .dtb from Android (you can find it in boot partition). And use the Armbian build for hinlink-h28k:
./compile.sh build BOARD=hinlink-h28k BRANCH=legacy BUILD_DESKTOP=yes BUILD_MINIMAL=no DESKTOP_ENVIRONMENT=mate DESKTOP_ENVIRONMENT_CONFIG_NAME=config_base EXPERT=yes KERNEL_GIT=shallow RELEASE=jammy
Somehow it works. But you need more changes in the config to make it work better.
After changes in device tree and linux-rk35xx-legacy.config: I have Lima (GPU driver for Mali-450) working, HDMI working, TV-out working, TV-audio working. But I can't get HDMI-audio to work (there is a driver, but still no sound).
Have a box with rk3528 here and did some work some weeks ago, mainly to get a kernel and multitool running on it.
It works, but I didn't publish an image for it yet (only available in source code), plus my board does not want to boot from sdcard and had no time and no will to further study it better.
