When I updated UBoot on my BeagleBone Green, I noticed that it prefers to load UBoot from the on-board eMMC device. (I had only updated it on the uSD card at that point and when I reset the board it loaded the old UBoot.)
To get my BeagleBone Black to boot from the SD card slot by default, I simply deleted the bootloader on the eMMC. Something like:
# mmc erase 0 1000 from U-Boot should do the trick. Cheers, Jared
