[U-Boot-Users] Newbie Question on rootfs.ext2.gz.uboot
I have a root file system that I boot over NFS (x86 host, PPC target).
How do I transform that into a root file system of the form rootfs.ext2.gz.uboot so I can load that into flash?
Happy to RTFM if someone can point me to it. And yes, I confess, I'm a newbie to this. :)
Cheers and Thanks!

Take a look at the genext2fs tool (http://genext2fs.sourceforge.net/) that also comes with the ELDK. It creates an ext2 filesystem image. Then use gzip to compress and finally use mkimage (part of the ELDK as well) to make it bootable by u-boot.
Alternatively you can do the genext2fs steps by hand (loopback mount an image file ....), but you need to become root to do this.
I think there are some hints in the Denx'Wiki.

This is indeed a RTFM job. Details can be found in the README (surprise!) and in the manual (surprise!), see for example http://www.denx.de/wiki/view/DULG/RootFileSystemDesignAndBuilding
