After many unsuccessful attempts in getting the Rock64 to boot from eMMC post Vanilla Debian install, it seems that the Debian installer is unable to flash a working u-boot to the eMMC.
Then I compiled U-Boot from scratch and flashed it to the eMMC which broke the Vanilla Debian installation, as Debian uses a similar setup to Arch with boot.scr file and U-Boot from scratch seems to expect a extlinux.conf file. :-\
So in the end I followed and amended this guide https://www.kulesz.me/post/140-debian-de...4-install/ here so that it fits my needs.

Now my Rock64 boots Debian from eMMC and works quite fine, except every time when UART0 is not connected the HDMI output is also not activated. When I attach UART0 my HDMI output comes back.
I suspect something is missing from my extlinux.conf file
