Re: How to use the beagleboard.img.gz on a BeagleBone Black



For BeagleBone Black, MLO and U-Boot is on the eMMC out of the box and beagleboard.img (7.0) / armv7.img (-current) is supposed to work as-is.

The supplied uEnv.txt does a few things -- first, it depends on U-Boot to read it, run the "loaduimage" command, and it must have "board=am335x" in the environment.

If you get a U-Boot prompt, try interrupting the countdown and running the following commands:

  fatload mmc 0 82000000 bbone.ub
  bootm 82000000 root=ld0a

Theres not even a u-boot binary on the fat partition of the image.

No, the u-boot typically goes at some fixed offset in the image, and
you have to prepare it specially for the device, so you won't find it
in the fat partition.

And since the u-boot version needs to match the device, we do not distribute
any of them with the image itself.
