[Gumstix-users] Help flashing NAND on Airstorm?

[Steven G. <ste...@ou...>]

Hi all,

I'm new to all of this and right now I am trying to flash my NAND to a fresh
Angstrom Linux installation. More specifically, the console version in this
link:
http://cumulus.gumstix.org/images/angstrom/developer/2011-08-30-1058/

I've followed the directions listed on the Gumstix developer's site:
http://gumstix.org/how-to/70-writing-images-to-flash.html
I've downloaded the MLO, uImage.bin, and u-boot.bin as well as the .ubi
installation image in the first link above. I put this in a bootable micro
SD and the flashing process completes error free. However, when I reboot and
both before or after I redundantly copy over the MLO into the flash, I'm
unable to boot into Angstrom. I will provide a dump if someone wants, but
its best described as the boot loader searching through every bit of the
flash and everything seems to be empty. At the very end, VFS gives me an
error saying it can't open root device and lists some available partitions
and then proceeds to kernel panic (posted below at the end).

After searching some things, I've found someone who posted slightly
different directions and uses a tar.gz2 rather than .ubi image:

Needless to say, this did not work as well, giving me a similar VFS error
and kernel panic. It's interesting to note that this method does not prompt
the boot loader to search through the entire NAND and whatnot. I assume that
mtdblock4 is where the rootfs should be but for some reason the flashing
process did not go successfully. I'm unsure. Someone in the comments said
they successfully flashed their NAND by information in this topic but I was
unable to get anything to work by blindly doing what people posted:

Anyhow, if anyone can help me by giving me directions on how to flash my
NAND, I would greatly appreciate it! 

Thanks!

VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available
partitions:
1f00             512 mtdblock0  (driver?)
1f01            1792 mtdblock1  (driver?)
1f02             256 mtdblock2  (driver?)
1f03            4096 mtdblock3  (driver?)
1f04          517632 mtdblock4  (driver?)
