UBI error: vtbl_check: volume table check failed

[Shane Volpe]

I'm running kernel version 2.6.28 and I have both UBI and UBIFS
compiled into the kernel.  I'm using an AT91SAM9260 with 512MiB of
NAND flash.  Here is what I ran to generate my ubifs image:

mkfs.ubifs -r rootfs -m 2048 -e 129024 -c 2047 -o ubifs.img
ubinize -o ubi.img -m 2048 -p 128KiB -s 512 ubinize.cfg

Here is my ubinize.cfg:
---START CONFIG
[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=500MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize
----END CONFIG

Here is my Kernel command line:
mem=32M console=ttyS0,115200 ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs

I erased the entire NAND flash and flashed the ubinized UBIFS image to
address 0x00a00000 which is mtd1.  I then boot my system and received
the error message(s) below (end of email).  I'm assuming, based on the
error, that the problem is the ubi driver can not find the header
information for the ubi partition however I'm not sure what I have
done wrong as I believe all of the settings were correct.  I would
appreciate any feedback as to what I might be doing wrong or other
things I may do to debug this issue.
Regards,
Shane
