Hi Guys,

I am tring to setup ubifs on an blackfin based embeded platform containg 
nand flash.
jffs2 is working ok on it.

So I have compiled the uclinux (kernel 2.6.28.10) with ubifs/mtd_ubi static 
support
If I pass with the bootargs ubi.mtd=3 , during booting I see

...
UBI: attaching mtd3 to ubi0
UBI: physical eraseblock size: 262144 bytes (256 KiB)
UBI: logical eraseblock size: 258048 bytes
UBI: smallest flash I/O unit: 2048
UBI: VID header offset: 2048 (aligned 2048)
UBI: data offset: 4096
UBI: empty MTD device detected
UBI: create volume table (copy #1)
UBI: create volume table (copy #2)
UBI: attached mtd3 to ubi0
UBI: MTD device name: "persistent file system"
UBI: MTD device size: 1004 MiB
UBI: number of good PEBs: 3974
UBI: number of bad PEBs: 42
UBI: max. allowed volumes: 128
UBI: wear-leveling threshold: 4096
UBI: number of internal volumes: 1
UBI: number of user volumes: 0
UBI: available PEBs: 3931
UBI: total number of reserved PEBs: 43
UBI: number of PEBs reserved for bad PEB handling: 39
UBI: max/mean erase counter: 0/0
UBI: background thread "ubi_bgt0d" started, PID 122
...

ubinfo gives me

root@pr1:~> /bin/ubinfo
UBI version: 1
Count of UBI devices: 1
UBI control device major/minor: 10:63
Present UBI devices: ubi0

I don't have /dev/ubi0 nor /dev/ubi_ctrl, however I do have some ubi stuff 
in my /sys file system

root@pr1:~> ls /sys/class/ubi/ubi0/
/sys/class/ubi/ubi0/avail_eraseblocks /sys/class/ubi/ubi0/min_io_size
/sys/class/ubi/ubi0/bad_peb_count /sys/class/ubi/ubi0/mtd_num
/sys/class/ubi/ubi0/bgt_enabled /sys/class/ubi/ubi0/reserved_for_bad
/sys/class/ubi/ubi0/dev /sys/class/ubi/ubi0/subsystem/
/sys/class/ubi/ubi0/eraseblock_size /sys/class/ubi/ubi0/total_eraseblocks
/sys/class/ubi/ubi0/max_ec /sys/class/ubi/ubi0/uevent
/sys/class/ubi/ubi0/max_vol_count /sys/class/ubi/ubi0/volumes_count

root@pr1:~> ls /sys/class/misc/ubi_ctrl/
/sys/class/misc/ubi_ctrl/dev /sys/class/misc/ubi_ctrl/uevent
/sys/class/misc/ubi_ctrl/subsystem/

I don't have /dev/ubi_ctrl so I can not crete (ubimkvol) ubi volume.

Can you please give me some pointers.

Best Regards
Dimitar Penev

Either make udev work and create device nodes for you automatically,
or create them manually. All the major/minor numbers are available
in sysfs (sedd "dev" files), so you may create corresponding character
device files.

udev isnt going to happen.  if the stuff is available via sysfs, then
`mdev -s` should work.

Or CONFIG_DEVTMPFS=y and CONFIG_DEVTMPFS_MOUNT=y in current bleeding edge
2.6.31+.
