I am having the same problem. Can boot from sd but not from emmc. Tried several images. Even tried the "u-boot-flash-spi-rockpro64.img.xz" mentioned above, but I can't see what going on when I boot that from the sd. It has no hdmi output, but I do see some flashing led lights after a minute or so. None the less, still could not boot from the emmc.
