Do you mean NAND flash, not ROM?  The Sakoman instructions worked for me: www.sakoman.com/OMAP/how-to-write-an-ubifs-rootfs-image-to-nand.html   You have to follow the instructions to the letter.

>Also is there a way to pull a ubi image of the device and expand it out to a directory tree?

You should be able to copy the filesystem image and mount it on your host system...but I've never done it.  I just tar, as you say.

Subject: [Gumstix-users] How to make a ROM image.

Are there any instructions on how to create a ROM image rootfs file?   I saw the wiki page http://www.gumstix.org/how-to/70-writing-images-to-flash.html  I am unfamiliar with a .ubi and Googleing around did not enlighten me.      

Also is there a way to pull a ubi image of the device and expand it out to a directory tree?   The second question is not so important because I can always tar off the root file system to an SD card.

Thank for your help,

David Moffatt.
