Ok, I did not see this yesterday, the C's we blank on my end. Anyway, "CCCCCCCC. . ." means that the board can not find a suitable bootloader. Which in this case I'm not sure if this is firstage ( MLO ) or second stage ( uboot ). But this is odd since the Beaglebone green is exactly the same board as the Beaglebone black, with just a few differences. I have not followed Roberts build from scratch guide in a year or more so I've not experienced this personally. However I can say that the latest Jessie testing image boots both as I very recently did just that. Booted both off the same sdcard.
