UBINIZE and UBIFS

UBINIZE and UBIFS

[Jacky Lam]

Dear all,

	I have a problem of embedding a UBIFS image by ubinize. Here is the
config file I am using:
===============================================================
[rootfs]
mode=ubi
image=rfs.bin
vol_id=0
vol_size=10485760
vol_type=dynamic
vol_name=rootfs

[areatest]
mode=ubi
image=test.bin
vol_id=1
vol_size=15728640
vol_type=dynamic
vol_name=areatest

[areauser]
mode=ubi
image=areauser.bin
vol_id=2
vol_size=47185920
vol_type=dynamic
vol_name=areauser
================================================================================

	areauser.bin is created by:

	mkubifs -v -g 1 -r areauser -o areauser.bin -m 4096 -e 516096 -c 92 -x none

	The final image is created by:

	ubinize -o final.raw.2 -m 4096 -p 512KiB ubinize_all.cfg	


	After burning the raw image to nand flash, everything works fine and
ubifs can be mount successfully. All the files are readable. But after I
unmount the ubifs and want to mount again. The following error is happened:
------------------------------------------------------------------------
...
<Many ECC errors reported>
...
UBI error: ubi_io_read: error -74 while reading 516096 bytes from PEB
55:8192, read 516096 bytes
UBIFS error (pid 42): ubifs_scan: corrupt empty space at LEB 1:4691
UBIFS error (pid 42): ubifs_scanned_corruption: corrupted data at LEB 1:4691
UBIFS error (pid 42): ubifs_scanned_corruption: first 4096 bytes from
LEB 1:4691
UBIFS error (pid 42): ubifs_scan: LEB 1 scanning failed
...
<Many ECC errors reported>
...
UBI error: ubi_io_read: error -74 while reading 516096 bytes from PEB
55:8192, read 516096 bytes
UBIFS error (pid 42): ubifs_recover_master_node: failed to recover
master node
mount: mounting ubi0:areauser on /mnt/areauser failed: Invalid argument

-------------------------------------------------------------------------

	However, if I runtime update the areauser.bin by ubiupdatevol, there is
no such problem.

	I have no cue on this, could anyone give me some suggestion?

	Thanks.

BR,
Jacky

Your image burning tool has issues. You can try the ubi flasher tool
from the mtd-utility.
Anyway, you should drop program the page with all 0xff if you are
using MLC nand flash.
