I have attempted to flash the Debian image to the eMMC on my Rock960A and every time it fails to boot after flashing.
I hooked up the UART cables and I get this message when attempting to boot:

I’m not sure if this is related, but my reset button doesn’t seem to work so I boot into Maskrom mode by holding the Maskrom button while plugging in the power.
