Hi Dwarkesh
As you said ,char device is enabled .Correct rootoption is given in U-boot environment .. My mtdparts are given below

U-boot MTDPARTS:

It is my Cmdline Parameter command line: console=ttyO0,115200n8 root=ubi0:rootfs rw ubi.mtd=NAND.file-system,2048 rootfstype=ubifs rootwait=1

I dont know why i am getting ubi error..

Hi,

Can you share the full bootlogs ? Also check if mtdparts is passed in command line, if not try passing it.

Hi,
One more thing, how did you flash the ubifs into the required partition ?

Hi
I am flashing to NAND from u-boot by following commands.

fatload mmc 0 $loadaddr zImage

nand write $loadaddr NAND.kernel

fatload mmc 0 $loadaddr am335x-boneblack.dtb

nand write $loadaddr NAND.u-boot-spl-os

nand erase 0xa00000 0x2000000
fatload mmc 0 $loadaddr rootfs.ubifs
nand write $loadaddr 0xa00000 0x2000000
run nandboot

U-boot env variables for NAND is as follows

nandargs=setenv bootargs console=${console} ${optargs} root=${nandroot} rootfstype=${nandrootfstype}
nandboot=echo Booting from nand ...; run nandargs; nand read ${fdtaddr} NAND.u-boot-spl-os; nand read ${loadaddr} NAND.kernel; bootz ${loadaddr} - ${fdtaddr}
nandroot=ubi0:rootfs rw ubi.mtd=NAND.file-system,2048
nandrootfstype=ubifs rootwait=1


Creation of Ubifs from poky-morty.

MKUBIFS_ARGS = " -F -m 2048 -e 129024 -c 1580"
UBINIZE_ARGS = "-m 2048 -p 128KiB -s 512 -O 2048"

i have tesed in SD boot , using mtd-utils , format the mtd partition and able to mount ubifs filesystem ..

Regards
Rajalakshmi A

Hi
With mtdparts parameter in command line,also getting same error.

Hi
Here i have shared my complete boot log for your reference.
