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

- May be used to emulate instructions that are not defined for

a particular processor implementation.

Follow-ups

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:

root:/> ubiformat /dev/mtd1 -f ubi.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: 907 eraseblocks are supposedly empty

ubiformat: warning!: 85 of 992 eraseblocks contain non-ubifs data

ubiformat: continue? (yes/no) yes

ubiformat: warning!: only 0 of 992 eraseblocks have valid erase counter

ubiformat: erase counter 0 will be used for all eraseblocks

ubiformat: note, arbitrary erase counter value may be specified using -e

option

ubiformat: continue? (yes/no) yes

ubiformat: use erase counter 0 for all eraseblocks

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

UBIFS: default compressor: lzo

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.

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

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

Close.
