Hi, I am trying to boot UBIFS based rootfs on NAND flash.
Upon mounting, I found the rootfs is mounted readonly without any messages..
My kernel command line parameters are as below.

setenv bootargs console=ttyO2,115200n8 rootfstype=ubifs rw
ubi.mtd=10,2048  root=ubi0:rootfs; setenv nandargs setenv bootargs
console=ttyO2,115200n8 rootfstype=ubifs rw ubi.mtd=10,2048
root=ubi0:rootfs;
saveenv;

Here is the fstab entry

none                 /dev/pts             devpts     defaults              0  0

Here is the inittab

::sysinit:/bin/mount -t proc proc /proc

Also, I flashed image after erasing the partion followed by ubiformat.

Here is the complete boot log, any help would be appreciated.
