Did you update the on-board U-Boot using the u-boot-flash-spi-rockpro64.img.xz image ? I make an sdcard from this image, boot the board with it let it do what it wants, shutdown, remove this sdcard, and then I can boot off eMMC images. Instructions for this are NOT clear. I have had to do this on both of my RockPro64's.
