UBIFS Informations

[simon widmer]

Update: I tested on Kernel 2.6.24-24 without success. The same manner if 
i want to mount the image. What I discovered is that i noted earlier 
that i have to compile with:

$ mkfs.ubifs -q -r $PATH\/data_h -m 2048 -e 129024 -c 2047 -o temp_h.img
$ ubinize -o data_h.img -m 2048 -p 128KiB -s 512 ubinize_h.cfg

and i have no idea what option "-q" is (neither does mkfs.ubifs). so I 
just kicked it and compiled with:

$ mkfs.ubifs -r $PATH\/data_h -m 2048 -e 129024 -c 2047 -o temp_h.img
$ ubinize -o data_h.img -m 2048 -p 128KiB -s 512 ubinize_h.cfg

ubinize.cfg looks this way:

[data_h]
mode=ubi
image=temp_h.img
vol_id=0
vol_size=4MiB
vol_type=static
vol_name=data_h
vol_flags=autoresize

and the attaching procedure as follows:

UBI: attaching mtd8 to ubi0
UBI: physical eraseblock size:   131072 bytes (128 KiB)
UBI: logical eraseblock size:    129024 bytes
UBI: smallest flash I/O unit:    2048
UBI: sub-page size:              512
UBI: VID header offset:          512 (aligned 512)
UBI: data offset:                2048
UBI: attached mtd8 to ubi0
UBI: MTD device name:            "data_h"
UBI: MTD device size:            4 MiB
UBI: number of good PEBs:        32
UBI: number of bad PEBs:         0
UBI: max. allowed volumes:       128
UBI: wear-leveling threshold:    4096
UBI: number of internal volumes: 1
UBI: number of user volumes:     1
UBI: available PEBs:             0
UBI: total number of reserved PEBs: 32
UBI: number of PEBs reserved for bad PEB handling: 2
UBI: max/mean erase counter: 2/0
UBI: image sequence number: 165352633
UBI: background thread "ubi_bgt0d" started, PID 497

and finally the mounting procedure:

UBIFS error (pid 529): ubifs_read_node: bad node type (0 but expected 6)
UBIFS error (pid 529): ubifs_read_node: bad node at LEB 0:0
mount: wrong fs type, bad option, bad superblock on ubi0_0,
        missing codepage or helper program, or other error
        (UBIFS error (pid 529): ubifs_read_node: bad node type (0 but 
expected 6)
for several filesystems (e.g. nfUBIFS error (pid 529): ubifs_read_node: 
bad node at LEB 0:0
s, cifs) you might
        need a /sbin/mount.<type> helper program)
        In some cases useful info is found in syslog - try
        dmesg | tail  or so
