What did you pass as "root" to the kernel?


That is a strong indication you did not set up the rootfs partition on the sdcard correctly. First thing: get a stable build image.

Use the RCN image-builder scripts to create an sdcard image and then flash it to an sdcard. See instructions at:

More info:

  • If you have a BBB v3 then use 4gb image (for debian that is bone-debian-7.6-lxde-4gb-armhf…), all other BBB versions use the 2gb iimage.

  • Start with the debian 7.6 rootfs until you REALLY understand what you’re doing.

  • To understand the mapping between the rootfs and the flash image look at the generated script in deploy/

  • There is a lot of stale info about building the BBB. image-builder is the best and most up-to-date starting point for BBB work.
