I just had to learn more about ubi utilities and read problems. What is the difference with ubi and ubifs files Bitbake gerantes? ubifs is 1MB smaller and actually it didn't want to work nice, but ubi worked fine. After few times of trying it is booting!

For rootfs there are two files generated, ubi and ubifs. So I tried putting ubi file onto mtd4, but it pretty much fails.

I used a small (~8MB) rootfs images with the Verdex board. Iirc, I treated those in the same way I treated JFFS2 images: I transferred those over a serial connection to the board using the U-Boot and then erased the flash with "erase" command and flashed the rootfs with "cp.b" command. Nowadays I have an Overo board and I use the Micro SD card for convenience. Looks like you already got good answers in gumstix mailing list.

But even if I manage to get ubi image (Bitbake handles that, I think) How to flash Gumstix with this new file system does the standard flash script works? http://www.gumstix.net/Setup-and-Programming/view/Overo-Setup-and-Programming/Writing-images-to-onboard-nand/111.html -david Hi,

So you have your linux distro and you put that to the file system. You can find more details from the UBIFS page: http://www.linux-mtd.infradead.org/doc/ubifs.html I'm not quite sure what you are trying to do but if you need to retrieve your IPAQ's file system then UBIFS isn't anything you need. And you can't put UBIFS on e.g. a harddrive, you need a flash device. UBIFS is a file system format, like e.g. EXT2, JFFS2 and VFAT. So you have your linux distro and you put that to the file system.

I mean do I need a linux distro like ubuntu and build it up or it is a separate specific distro? I would setup a notebook with ubifs to conenct and read the onenand on my ipaq: I just need read it possibly with all bad blocks, so a read only version is all I need. Maybe I a messing up with my spare knowledge ...:) anyway thanks sax Hi
