I have the feeling that uboot flash is not taken into account.
How long for flashing? I cut the power after one night.
As vincent indicated, this is NORMAL! The uboot-spi-flash image as small as it is because it does one thing only, writes uboot to the SPI flash. It does not have the extra baggage needed to output to a monitor, etc.
If you get the lights blinking, then it should be finished. Leave it for say 10-20 seconds after the lights flash to be sure. But it should take only a minute or two (faster if you're just erasing it).
And once you have powered off the rock64, pull the card out and put a different image on it or put a different card in with a linux or android build on it, otherwise it will just try to write uboot to the SPI flash the next time you power it on (again).
