Thanks for the detailed instructions Mark, I would have given up long before figuring this all out.
I tried a number of different terminal programs before digging out an old laptop with Ubuntu on it so I could "sudo apt install minicom" and follow your instructions here to the letter:
I also had trouble with my USB serial adapter, which didn't help.
I followed your advice and bought a CP2102 based device, see this example which has nice high res pics.
The trouble was, it didn't come with any instructions, nor could I find any online to explain what dip switch settings to use, especially given it can do 5V TTL, 3.3V TTL, RS232 etc.
So in case someone else buys the same product, here are the settings which work:
Switch 1: ON
Switch 2: OFF
Switch 3: towards Switch 2 (it's not labelled)
I was a bit reluctant to blindly try different switch combinations given it can do 5V logic as well, but I found the right settings on the third try and the Rock64 seems to have come out unscathed.
Once that was sorted it was plain sailing to follow your instructions on How to Write an Image to the eMMC Module.
So again, thank you. I understand this board is newly released, but the support here has been amazing and invaluable.
