UBIFS
- UBIFS used with raw flash memory media like NAND or NOR.
- UBIFS works on top of an unsorted block images device, which is itself on top of a memory technology device (MTD).
- The Unsorted Block Image File System (UBIFS) is a successor to JFFS2, and competitor to LogFS.

- http://www.linux-mtd.infradead.org/doc/ubifs.html
- https://www.kernel.org/doc/Documentation/filesystems/ubifs.txt
- http://elinux.org/UBIFS
- http://blog.csdn.net/emberic/article/details/6973305/
Creating ubifs image:
- Host# mkfs.ubifs -r <x> -m 4096 -e 516096 -c 320 -o rootfs.ubifs
This step will create rootfs.ubifs filesystem image.
put that in your NFS path.
Flashing the UBIFS Filesystem.
->Go to kernel source.
->Open menuconfig and enable the UBIFS support
->First Enable Device driver->MemoryTechnologydevice(MTD)-> Enable UBI - Unsorted block images

1) First you have to Format NAND Partition in which you want to put filesyetem. here is 3rd partition. If you get any warning say yes.

3) make volume of size 50MB. (please note my Partition size is 60 MB So I create only 50 MB Volume)

-------------------------------------------------------------------------
4) Write File-system in this volume.
Target# ubiupdatevol /dev/ubi0_0 <PATH TO Your created filesyetm>/rootfs.ubifs
5) Detach the 3rd partition.(specified with -m option)
Target# ubidetach /dev/ubi_ctrl -m 3
6) Set following bootargs and boot from NAND.

7) Reboot your board with compiled uImage, you will get following prints.

->Go to kernel source.
->Open menuconfig and enable the UBIFS support
->First Enable Device driver->MemoryTechnologydevice(MTD)-> Enable UBI - Unsorted block images
->Then Ebable Filesystem->Miscellaneous filesystems->UBIFS file system support
