Dear mailing-list,
I am still facing some trouble with UBI and UBIFS. I am working on an
OMAP4 processor with a 3.0.21 kernel and a Micron MT29F4G08ABBDAH4 1GB
NAND Flash.
I generate the ubi image of my rootfs using the following command:
mkfs.ubifs -r my_rootfs -o my_image.ubifs -m 2048 -e 129024 -c 4060
ubinize -o my_rootfs.ubi -m 2048 -p 128KiB -s 512 ubinize.cfg
And the following ubinize.cfg file:
[ubifs]
mode=ubi
image=my_image.ubifs
vol_id=0
vol_type=static
vol_name=my_rootfs
Then I flash this image and mount it with the following commands:
ubiformat /dev/mtd4 -f my_rootfs.ubi
ubiattach -p /dev/mtd4
mount -t ubifs ubi0_0 /media/test/
I then have the following error:
mount: block device ubi0_0 is write-protected, mounting read-only
And from the kernel (dmesg):
UBI warning: ubi_eba_read_leb: CRC error: calculated 0x34afeca5, must be
0x74215933
UBI warning: ubi_open_volume: volume 0 on UBI device 0 is corrupted
UBIFS warning (pid 226): init_constants_early: UBI volume is corrupted -

UBIFS: static UBI volume - read-only mode

UBIFS: journal size: 9033728 bytes (8822 KiB, 8 MiB, 71 LEBs)
UBIFS: media format: w4/r0 (latest is w4/r0)
UBIFS: default compressor: lzo
UBIFS: reserved for root: 0 bytes (0 KiB)
I couldn't find what I am doing wrong. Any help will be really appreciated !
Thanks in advance
Patrick
