Subject: UBI errors when "ls -l"
Date: Wed, 10 Dec 2014 09:34:22 +0000 (UTC) [thread overview]
Message-ID: <loom.20141210T102753-582@post.gmane.org> (raw)
Hi all,
My Kernel version is:
Linux swi-mdm9x15 3.4.91-yocto-standard #7 PREEMPT Wed Dec 10 17:39:02 HKT 2014
armv7l GNU/Linux
I am trying to mount ubifs. It seems mount ubifs image successfully, but when
access ubifs, it will print out lots of error msgs.
This is steps I do:
(1)make ubifs.image. I make ubifs image from *.conf (I tried use "mkfs.ubifs"
and "ubinize" to make image directly, the same error msgs ).
IMAGE_FSTYPES += "ubi"
MKUBIFS_ARGS = "-m 4096 -e 253952 -c 2047"
UBINIZE_ARGS = "-m 4096 -p 256KiB -s 4096"
(2)mount ubifs In Linux shell.
mkdir -p /mnt/ubifs
flash_erase /dev/mtd3 0 0 -N
dd if=/mnt/flash/ubi.img of=/dev/mtd3 bs=4096
ubiattach /dev/ubi_ctrl -m 3 -O 4096
ubiblkvol -a /dev/ubi0_0
mount -t ubifs ubi0:swi-mdm9x15-rootfs /mnt/ubifs
(3)After step (2), ubifs can be mounted successfully. But when I access ubifs,
such as when I input "ls", it will show lots of error msgs. But after printing
out error msgs, finally it will show directory.
By the way, I tried to use nandsim to debug the ubi image in Ubuntu, it is OK.
I think there is something wrong in Kernel configuration.
Could you please help me? Thank you very much!
Error msgs and Kernel configuration attached.
