I was never successful in using rkflashtool to work, with either the eMMC or SD cards.
I was able to flash the eMMC card by using a spare oDroid C2 that I had, writing to the card via it's SD interface and an SD->eMMC adapter, using some CLI commands described here.
For the image, I used the Xenial Mate 1G image from https://github.com/ayufan-rock64/linux-b...tag/0.5.15 . The more recent pre-leases failed to boot.
With the eMMC flashed with an released image, the board came up into the UI in under 3 seconds - very impressive.
