While successfully programming the eMMC on the Beaglebone Black following this procedure: 
the patch at the end of the page to modify U-Boot to boot from TFTP automatically does not work. I tried to apply the patch linked to but it does not take and looking at it's contents reveals that it does not line up with the files to be patched. Can anyone at TI update this so it works?
I am using Debian build 4.1 on the Beaglebone Black.
