Assuming use of 512MB Nand Flash on Arm7 (I am using AM3517), did someone use rootfs image other than jffs2 ??
Something like jffs3 or yaffs2. Definitely, jffs2 has issues for boot time and those are solved in jffs3 and yaffs which are much better designed for bigger nands.
My previous jffs2 was mounted on /dev/mtdblock4, device (31,4)
Now, I have tried to mount ubifs from uboot using next u-boot argline, seemed sensible to me:
nandargs=setenv bootargs console=${console} init=/sbin/init ubi.mtd=4 root=/dev/mtdblock4 rw rootfstype=ubifs
resulting in:
UBIFS error (pid 1): ubifs_mount: cannot open "/dev/root", error -22
There is not /dev/root, so I have also tried the suggested option from http://free-electrons.com/blog/creating-flashing-ubi-ubifs-images/
nandargs=setenv bootargs console=${console} noinitrd ubi.mtd=4 root=ubi0:rootfs rw rootfstype=ubifs
Got the next error messages:
UBIFS error (pid 1): ubifs_mount: cannot open "ubi0:rootfs", error -19
VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
...
Didn't spot any ubi* devices under the /dev for the arago typical rootfs (sdk 05.03.02.00), so built and flashed kernel image supporting DEVTMPFS and AUTO option, also as recommended in the above link, without any success. I have a strong feeling that my u-boot line is incorrect.
What have I done wrong?
Yakir
Additional information:
1. According to Ti's it is recommended to use -F option with mkfs.ubifs. I don't have this option on my mtd-utils installed on ubuntu precise VM.
2. Tried to use common sense and corrected TI's proposed command line args:
nandargs=setenv bootargs console=${console} noinitrd ip=off mem=256M rootwait=1 rw ubi.mtdblock=4,2048 rootfstype=ubifs root=1f:04
Got the following result:

Yakir,
Where ever you are looking currently is the end of the logs. If you go up, you'll be able to see the logs where it tries to create the mtd device and attach a UBI device. Once the device is attached, then only you'll be able to create or mount the UBIFS on top of it.
So, could you share the complete boot logs?
Yes, sure. Here the kernel boot logs:

Thanks,

Yakir,
You have not created a UBI volume on mtd4, without which you are trying to mount. First you've to create a UBI volume on mtd4 and format it to UBIFS. The same can be achieved by performing the above operations in kernel or you can do it by creating a UBI image and flash it from u-boot to mtd4's offset in NAND.
I am not sure that I haven't done what that. My actions were:
1. Created ubi.img file (~18MB) from mkfs.ubifs and then ubinize on ti's base rootfs (can specify the commands more in detail, if required)
2. Logged in u-boot and erased the mtd4 partition on the nand : starting 0x780000 size 0xF880000 by nand erase xxx xxx
3. Used "nandargs=setenv bootargs console=${console} noinitrd ip=off mem=256M rootwait=1 rw ubi.mtdblock=4,2048 rootfstype=ubifs root=1f:04" as a kernel boot argument
4. Flashed ubi.img to the 0x780000 address
5. Rebooted
The logs stand,
What do I miss?
Changed to the argument, now it looks like:
nandargs=setenv bootargs console=${console} noinitrd ip=off mem=256M rootwait=1 ubi.mtd=4 rootfstype=ubifs root=ubi0:rootfs rw
These are my reflashing ops:

Checked the rootfs, by the way: there is no /dev/root in the basic TI's rootfs. Should be?
Another thing, could it be because of incorrect image creation by mkfs.ubifs? I have observed that for nand flashes it is recommended to use -F option but I think my utility throws a usage() print saying no such cmd line option is supported.
Yakir,
-F option depends on the mtd-utils version.
If you can see the log, there is "Skip bad block 0x01220000" which will spoil the image's continuity in flash. Either you can do a nand scrub, which will try to remove the bad block.
Meanwhile can you try creating the UBI volume from kernel by following the below mentioned steps?
1. First you should have your rootfs as a tar ball in your SD card or NFS from where you mount the filesystem.
2. Boot up the device and the filesystem from NFS or SD card according your preference.
3. Boot it up and login. Hope you have all the required command binaries like "flash_erase" etc in your filesystem. If not take the default arago filesystem image that comes with the EZSDK package.
4. Follow the steps below
$ flash_erase /dev/mtd4 0 0
$ ubiattach /dev/ubi_ctrl -m 4
$ ubimkvol /dev/ubi0 -N rootfs -m
$ mkdir /mnt/nand
$ mount -t ubifs ubi0:rootfs /mnt/nand
$ tar xvf arago-base-tisdk-image-dm814x-evm.tar.gz -C /mnt/nand
5. Change the bootargs like below for booting from UBIFS.
# setenv bootargs 'console=ttyO0,115200n8 mem=160M ubi.mtd=4 rootfstype=ubifs root=ubi0:rootfs rw'
I have done as you have instructed booting from MMC and doing all commands which didn't provide any failures.
Then I have rebooted with the command like and received a similar message for it can't find the ubi0:roo... and I have to provide the correct root= arg, bla bla...
So, I have again altered the argument to have root=1f:04 and got the following kernel log, still kernel panics. I have made bold the log line that I see suspicious or related. Please advice.
Starting kernel ...
Uncompressing Linux... done, booting the kernel.
