I just built Angstrom via oe-core for the BeagleBoard, rev C3 (not xM)
Here were my steps:
$ git clone git://git.angstrom-distribution.org/setup-scripts angstrom-bb
$ cd angstrom-bb
$ git checkout -b local-oe origin/oe-core
$ MACHINE=beagleboard ./oebb.sh config beagleboard
$ MACHINE=beagleboard ./oebb.sh bitbake console-image
It doesn't boot at all. I built a bootable SD from the deploy/images,
including MLO and U-Boot. Here's the boot sequence (I broke in to set
the console):
Texas Instruments X-Loader 1.4.4ss (Jan 29 2011 - 10:54:03)

Looking around after it hangs, it seems that it didn't get
started at all. Normally, there will be some crumbs left
over in the system log buffer:
$ grep __log_buf

Any ideas what's wrong? Shouldn't this work out of the box? - I tried
to follow the directions on
http://www.angstrom-distribution.org/building-angstrom
closely, save the part of using the oe-core based script.
