Yes they shipped the eMMC with some boot and OS on the chip. I overwrote them with the rockpro64 image though before booting on the board.

AmeriDroid maybe provided eMMC with pre-loaded with some unkown version of U-Boot, and as any Rockchip SoC start looking at eMMC before trying SDCard, this eMMC U-Boot has priority.

I tried copying the entire working disk contents from the SD card to the (again blank) eMMC card; unfortunately I still get the same issue with only the eMMC card connected.

So, it appears that if there is any boot sector on the eMMC present, then the system hangs after `reboot` command. If there is an SD card present with boot sectors, and the eMMC is present with no boot sectors, then the issue does not happen. I have also written some filesystem to the eMMC card and mounted it at boot which was fine. Its just if the eMMC has boot sectors does the issue occur.
