Summary: fail to flash ubifs.img to nand

Details:

fail to flash ubifs.img to nand.

I made a ubifs.image from romfs with mkfs.ubifs on host, like:

./mkfs.ubifs -r ../../romfs/ -m 2048 -e 129024 -c 100 -o ubifs.img

and copy this image to target board, but fail to ubiformat it to nand.

root:/> ubiformat /dev/mtd1 -f ubifs.img -s 512 -O 512

ubiformat: mtd1 (NAND), size 130023424 bytes (124.0 MiB), 131072 eraseblocks of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes

libscan: scanning eraseblock 991 -- 100 % complete

ubiformat: 990 eraseblocks have valid erase counter, mean value is 4

ubiformat: bad eraseblocks: 679, 746

ubiformat: error!: file "ubifs.img" (size 6967296 bytes) is not multiple of eraseblock size (131072 bytes)

           error 0 (Success)

And I have tried to use ubinize to transform it, like:

root:/> ubinize -o ubi.img -m 2048 -p 128KiB ini_file

test@uclinux55-bf537-cf-spi:..uclinux-dist/logs> cat ~/ini_file

[ubifs]

mode=ubi

image=ubifs.img

vol_id=0

vol_size=20MiB

vol_type=dynamic

vol_name=ubifs0

vol_flag=autoresize

vol_alignment=1

this also fails with :

Undefined instruction

   a particular processor implementation.

Follow-ups

--- Barry Song                                               2009-10-19 00:34:22

As a step of ubi image building, I think we should run "ubinize" on PC

host but not on targets. Then run "ubiformat" on targets and write the

transformed ubifs.img to /dev/mtdx.

Here I get different result with you:

host:

root@roc-desktop:~# mkfs.ubifs -r test -m 2048 -e 129024 -c 100 -o ubi.img

root@roc-desktop:~# ubinize -o ubi.img -m 2048 -p 128KiB ubifs.conf

root@roc-desktop:~#

target:

Test show ubifs can work on our system:

root:/> ubiattach /dev/ubi_ctrl -m 0

root:/> ubimkvol /dev/ubi0 -N par1 -s 2MiB

root:/> mount -t ubifs ubi0_0 /mnt/

UBIFS: mounted UBI device 0, volume 0, name "rootfs"

UBIFS: media format:       w4/r0 (latest is w4/r0)

UBIFS: reserved for root:  54846 bytes (53 KiB)

root:/> ubinfo

UBI control device major/minor: 10:63

Present UBI devices:            ubi0

root:/> mount

...

ubi0_0 on /mnt type ubifs (rw,relatime)

But we need to figure out the right setting for mkfs.ubifs and ubinize

according to the hardware feature of nands we are using, then write right image

to nand.

--- Barry Song                                               2009-10-19 05:02:49

The right configuration for nand on bf537 should be:

host: building ubi image

mkfs.ubifs -r romfs -m 2048 -e 129024 -c 4096 -o ubifs.img

ubinize -o ubi.img -m 2048 -s 512 -p 128KiB ubifs.conf

target:write image, attach and mount:

Yeah, after enlarging the stacksize of ubiformat, it is working on my side too.
