Final update, issue was with armbian-upgrade restoring the dtb to the original files. Skipping dtb update should be enough. I was also able to install to emmc by using the armbian-install script.
Everything seems to be running pretty stable so far. Thanks @mmie4jbcu for your help!
I got the station m2 debian minimal image to work with the changes you suggested. Everything worked fine but as soon as I ran armbian-upgrade, wifi, usb etc broke. Does that mean that we cannot run updates?
Thanks for the response, I went through them already and it looks like the development on it went stale. I read that all RK3566 TV Boxes have the same internals so was hoping to use this build.
