Big thanks to balbes150 for supporting this project and everyonelse answering questions as well.
I was able to boot from the USB drive into Armbian but run into an issue when copying to eMMC.
It is intermittent, but it seems that Armbian is not seeing my internal memory. In those rare cases when it does (mutliple reboot tries) it throws errors (see below) when I run install script.
At this moment of time I am about to give up, as I've spent 2 days on this issue trying different images.
Is there anything else I can do?
