JC 03:00 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND

Thanks for the procedure. In case you weren't aware I wrote up a guide on doing this without the kernel being stored in the ubifs partition. [[UBIFS_Nand_Boot]]
I'll definitely try to take some time to add your method as an alternati... Jonathan Cormier

The procedure is simple - I create a UBI image (mkfs.ubifs & ubinize) with uImage and rootfile system volumes and programmed it into flash. There are lots of places on the web that explain this process, and once you have a UBI image you... Michael Karasoff

Michael,
I've added your changes including my alternative change to a test branch on my machine. If you could test my alternative change I'll happily post it up on our site.
Thanks Jonathan Cormier

Ok cool. We've never tried storing the kernel in a ubifs partition. If you have it working I'd be interested in your procedure. Jonathan Cormier

Do you have a reference for your first change? Or did you find this through trial and error? Jonathan Cormier

Michael,
You should be able to replace your second change with: Jonathan Cormier

To boot from UBI with the 512MB NAND, I had to modify the 2013.01 branch bootloader: Michael Karasoff
