I was told to use at least 3.14 and build an image from here: http://elinux.org/BeagleBoardDebian. Doing that caused U-Boot to complain with "** Invalid partition 2 **" and then dump me back to the U-Boot prompt. Googling on this led me to this: https://github.com/RobertCNelson/netinstall/issues/32. The suggested fix is to boot something from http://elinux.org/BeagleBoardUbuntu#BeagleBone.2FBeagleBone_Black and then do "sudo dd if=/dev/zero of=/dev/mmcblk1" and try again. Now when I boot the BBB without an SD card, I get the letter 'C' repeated every half a second. Did I just blow away the MMC bootloader?

For the 'netinstall' it's a more pain in the ass, so I just require it.
