UBIFS error

Ankur Tank

Hello,

We are using MT29F8G08ABABA in our DM365 based custom board.
We are using NAND boot.
RootFS is in UBIFS format,

Below is basic achitecture of the NAND.

I am using following commands to create ubifs,

$(UBIFS_PATH)/mkfs.ubifs -r  $(TARGET_FS) -m 4096  -e 520192 -c 75 -o ubifs.img
$(UBIFS_PATH)/ubinize -o $(SYSTEM_CFG)_$(HARDWARE_CFG)_ubifs -m 4096 -p 512KiB $(HARDWARE_CFG)_ubinize.cfg

Then i put this ubifs to NAND using following commands,

loady 0x82000000 ---> ubifs is loaded to RAM

nand scrub 0x1800000 0x2800000
nand erase 0x1800000 0x2800000
nand write 0x82000000 0x1800000 0x2800000

and when i boot the kernel there is error while detecting UBIFS from kernel,

Below is kernel log for the same,

Now my doubt is why kernel is reporting physical eraseblock size as 256KiB? from architecture of NAND it looks to be 512KiB.

dm368_ubinize.cfg content is as follows,

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=37888KiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

Any suggestions/pointer for the errors ?

Thank you in advance

Ankur,

Can you check by the flashing the ubi image from kernel using ubiformat after booting through NFS or SD? Follow these steps.

1. First you should have your rootfs as a tar ball in your SD card or NFS from where you mount the filesystem.
2. Boot up the device and the filesystem from NFS or SD card according your preference.
3. Boot it up and login. Hope you have all the required command binaries like "flash_erase" etc in your filesystem. If not take the default arago filesystem image that comes with the SDK package.
4. Follow the steps below

$ flash_erase /dev/mtd4 0 0
$ ubiattach /dev/ubi_ctrl -m 4
$ ubimkvol /dev/ubi0 -N rootfs -m

$ mkdir /mnt/nand
$ mount -t ubifs ubi0:rootfs /mnt/nand
$ tar xvf rootfstar.gz -C /mnt/nand

5. Change the bootargs like below for booting from UBIFS.
# setenv bootargs 'console=ttyO0,115200n8 mem=160M ubi.mtd=4 rootfstype=ubifs root=ubi0:rootfs rw'

Hi Renjith,

Thank you for reply,

We don't have Ethernet phy up as yet, SD Card is also not there in our board.

But as of now what i have done is i have flashed squashfs in mtdblock5 and i am able to boot the kernel from that.

I will follow the steps you mentioned to flash rootfs in mtd3 and let you know the results by Monday.

Regards,

Ankur

Hi Rejith,

One strange thing what I observed is,
When i boot kernel using squashfs from mtdblock5, ubi is mounting mtd4(8MB) partition as ubi0 device.
Here is bootlog for the same.

Hi Ankur,

plz refer the below websites for all ur UBIFS related questions

http://processors.wiki.ti.com/index.php/UBIFS_Support
http://elinux.org/UBIFS
http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_UserGuide#Fastboot_and_UBI_rootfs

make your pendrive as a ext3 filesystem (kernel should support ext3/4 fs support) & copy the filesystem contents into pendrive with correct root permissions.

bootargs is "rootfstype=ext3 root=/dev/sda1"

and flash ur fs into /dev/mtd5 or 4 with any type of fs (better to use yaffs2 for simplicity & performance)

Hi Titus,

Thank you for reply,

I followed the steps mentioned in http://processors.wiki.ti.com/index.php/UBIFS_Support to create ubifs but it gives error. :(

I agree that instead of using UART for loading filesystem, its better to put rootfs in USB and boot from that.

I am also in favor of that. I am waiting for USB connector(both side usb receptical ), once i get it i will try booting from USB.

I have one doubt.

1. Does DM365 usb usable as host ? do need to load some driver to make as USB host ?

2. YAFFS2 is read-write file system right ?

Regards,

Ankur

Hi Renjith,

I have followed below steps to flash the ubi image from kernel as you have mentioned

ubidetach -h

ubidetach version 1.4.5 - tool to remove UBI devices (detach MTD devices from UBI)

Usage: ubidetach [<UBI control device node file name>]

[-d <UBI device number>] [-m <MTD device number>] [-p <path to device>]

[--devn=<UBI device number>] [--mtdn=<MTD device number>]

[--dev-path=<path to device>]

UBI control device defaults to /dev/ubi_ctrl if not supplied.

Example 1: ubidetach -p /dev/mtd0 - detach MTD device /dev/mtd0

Example 2: ubidetach -d 2 - delete UBI device 2 (ubi2)

Example 3: ubidetach -m 0 - detach MTD device 0 (mtd0)

-d, --devn=<UBI device number> UBI device number to delete

-p, --dev-path=<path to device> or alternatively, MTD device node path to detach

-m, --mtdn=<MTD device number> or alternatively, MTD device number to detach

-h, --help print help message

-V, --version print program version

After extracting file system content to ubi0, I rebooted board, set the bootargs as follows,

setenv bootargs 'mem=48M console=ttyS0,115200n8 noinitrd ip=off ubi.mtd=3 rootfstype=ubifs root=ubi0:rootfs rw cmemk.phys_start=0x83000000 cmemk.phys_end=0x88000000 cmemk.phys_start_1=0x00001000 cmemk.phys_end_1=0x00008000 cmemk.pools_1=1x28672 cmemk.allowOverlap=1 cmemk.useHeapIfPoolUnavailable=1 nohz=off highres=off clocksource=acpi_pm lpj=1077248'

but when I boot with this bootargs there are io read errors, and rootfs is not mounted,

I have attached boot log for your reference,

One thing i noticed is you mentioned ubiformat in beginning but in steps you havent mentioned that,

Did we miss that step ?

Any other suggestions/corrections ?

Hi Titus,

In kernel version 2.6.37, YAFFS option is not available in menuconfig itself,

I think i have to either go with ubifs or some other read-write file system.

Here is screenshot of menuconfig.

Any suggestions ?

I referred some of the online post regarding these errors and i found that this can be solved by using later version of mtd-utils.

what is your opinion/suggestion on that ?

And if have to get new mtd-utils version i have to update its dependency libs also to required version.

Do you suggest anything else ?

Thank you,

Hi,

In kernel version 2.6.37, YAFFS option is not available in menuconfig itself,

plz follow the below proced & change it according to ur req. and if need (like use ramdisk instead booting from SD card)

YAFFS2
=======

Flashing yaffs2 rootfs image
------------------------------------------

Refer:
http://processors.wiki.ti.com/index.php/YAFFS2_kernel_configuration

Step 1 :
Download 'yaffs2' source from the below website path.

http://aleph1.co.uk/gitweb?p=yaffs2.git;a=snapshot;h=HEAD;

Step 2 :
untar the downloaded file by 'tar' command

Step 3 :
Run the below command in host terminal for applying patch into working linux kernel

cd yaffs2-HEAD-bc76682
./patch-ker.sh l m < linux kernel path >

Ex:
./patch-ker.sh l m /home/am35x/linux-2.6.37

Step 4 :
Compile the kernel & copy into SD card then boot from SD card.

Step 5 :
Copy the rootfs tar file (rootfs.tar.gz) into 'rootfs' partition of SD card.

Step 6 :
Boot ur system with any tpye of booting method (without NAND) & do the below commands to flash rootfs into NAND flash.

root@am3517-evm:/# flash_eraseall /dev/mtd4

root@am3517-evm:/# mount -t yaffs2 /dev/mtdblock4 /mnt

root@am3517-evm:/# cd /mnt

root@am3517-evm:/# tar -zxvf /rootfs.tar.gz

root@am3517-evm:/# cd /

root@am3517-evm:/# sync

root@am3517-evm:/# umount /mnt

root@am3517-evm:/# init 0

Step 7 :
Do the below command to write the env variable for yaffs2 boot in u-boot terminal

u-boot # setenv nandargs setenv bootargs 'console=${console} rootwait=5 rw root=/dev/mtdblock4 rootfstype=yaffs2'

u-boot # saveenv

Step 8 :
Remove the SD card & boot from NAND flash.

UBIFS TESTING
==============

flash_eraseall /dev/mtd4
ubiformat /dev/mtd4 -s 512 -y
ubiattach /dev/ubi_ctrl -m 4

mount -t ubifs ubi0:ubi-rootfs /mnt/

< change fs as u like here (copy & untar ) >

ubidetach /dev/ubi_ctrl -m 4

umount /mnt

1. Does DM365 usb usable as host ? do need to load some driver to make as USB host ?

Yes possible, read TRM (technical ref manual of DM365)

2. YAFFS2 is read-write file system right ?

Yes

[ 109.717070] UBI: physical eraseblock size: 262144 bytes (256 KiB)

root@DM368_IPNC:~# flash_eraseall -j /dev/mtd3
Erasing 256 Kibyte @ 0 -- 0 % complete.libmtd: error!: unaligned address 2, mtd3 page size is 2048

Regarding NAND erase size(block size) - actual 512KB

Are you using right NAND flash which is approved NAND part by TI ?

[ 1.271588] Bad block table not found for chip 0
[ 1.277635] Bad block table not found for chip 0

If not need to modify linux & u-boot nand driver bcz ur facing "Bad block table(bbt) not found" message is displaying while bootup (loading nand driver)

Actually it should use bbt from u-boot which is updated & maintained by u-boot

plz chk out NAND driver & ECC layout

And if have to get new mtd-utils version i have to update its dependency libs also to required version.

Do you suggest anything else ?

If it so, then download latest source code & cross compile it and confirm it(it takes to less than 15min)

http://processors.wiki.ti.com/index.php/Mtdutils
http://processors.wiki.ti.com/index.php/MTD_Utilities

JFFS2 also simplicity unless you ll use >64MB bcz it use compression & takes more time to boot then YAFFS2 whereas yaffs2 is simple & quick boot

Hi Ankur,

There's nothing wrong in having an additional partition with UBI. If you are using IPNC stack, this partition will be used to save settings etc as this will R/W file system, where are SquashFS is read-only.

Hi Titus/Renjith,

Thank you very much for helping, finally I got UBIFS working on my board,

Here are commands I used to create the ubifs

$(UBIFS_PATH)/mkfs.ubifs -r  $(TARGET_FS) -m 2048 -e 258048 -c 506 -o ubifs.img

$(UBIFS_PATH)/ubinize -o $(SYSTEM_CFG)_$(HARDWARE_CFG)_ubifs -m 2048 -p 256KiB -O 2048  $(HARDWARE_CFG)_ubinize.cfg

content of ubinize.cfg is as follows,

[ubifs]
peb=0x40000
min_io_size=0x800
compress_type=zlib
mode=ubi
image=ubifs.img
vol_id=0
vol_size=124MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

Some calculations which will help understand

For 256Kib and pagesize 2048

Symbol  Meaning     Value for 128MB fs
SP  PEB Size    256KiB
SL  LEB Size    256kib - 2* 2kiB = 252Kib
P   Total number of PEBs on the MTD device  128MiB / 256KiB = 512
B   Number of PEBs reserved for bad PEB handling    1% of P = 5
O   The overhead related to storing EC and VID headers in bytes, i.e. O = SP - SL   4KiB 


UBI Overhead = (B + 4) * SP + O * (P - B - 4) 
      = (5 + 4) * 256Kib + 4 KiB * (512 - 5 - 4)
      = 2304Kib + 2012Kib
      = 4316 KiB 
      = 16.859375 PEBs (round to 17)

512 - 17 = 498 peb = 498*256kiB PEBS = 127488KiB availble for user data

we have to use -c <X> where x = 127488Kib / 252kib = 505.9 = 506

In my opinion Important point is, physical erase block size and page size

I have to consider block size as 256KiB. Block size mentioned in the datasheet of NAND is 512KiB BUT erase block size is not same as block size, it is the minimum size of block which can be erased. As there are two planes in the NAND and on each plane minimum block size is 256KiB, it should be considered as erase block size.

Same is the case with page size, in datasheet (above diagram) it is mentioned as 4096 but they are divided in the two planes, each plane contains 2048 size of page. So minimum io size is 2048.

(Let me know if my understaing is wrong/incomplete).

For more details one can refer below post in stackoverlow.
