Newbie question about boot process of Angstrom-Beagleboard-demo-image..

Hi All,

I have loaded Angstrom-Beagleboard-demo-image... on my unit and it
pretty much all works except for a network issue (a subject for a
different posting).

My next step is to start learning about the process of building a
custom version of Angstrom/OpenEmbedded, but before I get going on
that I am interested in learning more about the boot process of the

Three files are loaded on the FAT32 partition - MLO, u-boot.bin and
uImage, and the un-tarred contents of Angstrom-Beagleboard-demo-
image....rootfs.tar.bz2 on the ext3 partition.

Is there a description available for each of these files, and how each
is built and how they interact ?

I assume that if I am going to build a custom Angstrom/OpenEmbedded
system that an understanding of the boot process could be quite
useful :slight_smile:

I, being a newbie built my own angstrom images. It is fun.
