Hello all, I am struggling with booting the BBB REVC from 4GB class 10 uSD flashed with the image 4.1.21-bone-rt-r20 and u-boot image from branch v2016.07-rc2( I have followed all the steps from R.Nelson eewiki). when I press the S2 button and plug the 5V barrel supply I can see on my serial console CCCCCC while I was expecting at start to see all the 4 LEDS lighing on. I used the same uSD card and try it on the BBG, the board boots without even pressing the S2 button.
Its there sometime I need to setup in the u-boot in order to correctly boot off uSD? I am wondering why I have no problem with the BBG? As I know they use the same ARM Core? Thanks in advance for your answer.
