Hi,

We are trying to boot from Nand device for Am335x evmboard. We are using Micron MT29F4G08ABADAWP Nand, 512MiB.

While booting from Nand we are getting kernel panic error.

We have followed the below mentioned steps.

1.Created a ubifs.img using the following command

mkfs.ubifs -v -r /home/sachin/sdk6/targetNFS/ -m 2048 -e 126976 -c 4030 -o ubifs.img

o/p we got was:

mkfs.ubifs

root: /sdk6/targetNFS/

min_io_size: 2048

leb_size: 126976

max_leb_cnt: 4030

output: ubifs.img

jrn_size: 8388608

reserved: 0

compr: lzo

keyhash: r5

fanout: 8

orph_lebs: 1

super lebs: 1

master lebs: 2

log_lebs: 5

lpt_lebs: 2

orph_lebs: 1

main_lebs: 2723

gc lebs: 1

index lebs: 33

leb_cnt: 2734

UUID: 6B5E0208-BD1D-4F6E-9AA8-FD5CF37C7B85

Success!

2. Edited the ubi.ini file as shown below:

[rootfs-volume]

mode=ubi

image=ubifs.img

vol_id=0

vol_size=350MiB

vol_type=dynamic

vol_name=rootfs

vol_flags=autoresize

3.Created a ubi.img using the following command

ubinize -v -o ubi -m 2048 -p 128KiB -s 2048 ubi.ini

o/p:

ubinize: LEB size: 126976

ubinize: PEB size: 131072

ubinize: min. I/O size: 2048

ubinize: sub-page size: 2048

ubinize: VID offset: 2048

ubinize: data offset: 4096

ubinize: UBI image sequence number: 968051357

ubinize: loaded the ini-file "ubi.ini"

ubinize: count of sections: 1

ubinize: parsing section "rootfs-volume"

ubinize: mode=ubi, keep parsing

ubinize: volume type: dynamic

ubinize: volume ID: 0

ubinize: volume size: 367001600 bytes

ubinize: volume name: rootfs

ubinize: volume alignment: 1

ubinize: autoresize flags found

ubinize: adding volume 0

ubinize: writing volume 0

ubinize: image file: ubifs.img

ubinize: writing layout volume

ubinize: done

4. After this we used ubiformat -y /dev/mtd7 -f ubi on the custom board

o/p:

ubiformat: mtd7 (nand), size 529006592 bytes (504.5 MiB), 4036 eraseblocks of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes

libscan: scanning eraseblock 4035 -- 100 % complete

ubiformat: 4036 eraseblocks have valid erase counter, mean value is 1

ubiformat: flashing eraseblock 2735 -- 100 % complete

ubiformat: formatting eraseblock 4035 -- 100 % complete

5. After this we have given ubiattach /dev/ubi_ctrl -m 7 -O 2048 and we got segmentation fault as shown below:

Hi,

Which version of the SDK are you using?

Try to flash the mtd partitions from U-Boot as I have explained here: http://e2e.ti.com/support/arm/sitara_arm/f/791/p/268305/949397.aspx#949397

There are also explanations about the needed calculations. Verify that yours are correct.

Best regards,
Miroslav

Hi,

I have tried followings commands from u-boot

MLO

====

mmc rescan

fatload mmc 0 0x82000000 MLO

nand erase 0x0 0x20000

nand write 0x82000000 0x0 0x20000

nand erase 0x60000 0x20000

nand write 0x82000000 0x60000 0x20000

u-boot:

======

mmc rescan

fatload mmc 0 0x82000000 u-boot.img

nand erase 0x80000 0x001e0000

nand write 0x82000000 0x80000 0x001e0000

uImage:

=======

fatload mmc 0 0x82000000 uImage

nand erase 0x00280000 0x500000

nand write 0x82000000 0x00280000 0x500000

but my ubi.img is stored in the rootfs (mmc1), please teach me how to access ubi.img from the u-boot to flash in to NAND.

mmc0 has three images uImage,u-boot.img,MLO. mmc1 has the file system and ubi.img is in /root/

The U-Boot from the SDK you are using has the following command:

ext2load- load binary file from a Ext2 filesystem

Type "help ext2load" for more information.

There is no enough space available to store ubi.img in mmc0. My ubi.img file is 342 MB.i also tried using

fatload mmc 1 0x820000000 ubi.img ,but it is not coming out of that command.

Please suggest me in this regard.

Hi, There is no space to load ubi.img in the mmc0. ubi.img is stored in mmc1(rootfs partition of SD card). From u-boot terminal I tried ext2load mmc 0:1 0x82000000 /ubi.img O/p: Failed to mount ext2 filesystem... ** Unrecognized filesystem type ** Please teach me how to attach and mount ubi.img. Regards,

How is your rootfs partition formatted? Is it ext2 or ext3 or ext4? If it is ext4, the ext2load command won't work. To work around this issue, either format the partition as ext2 or enable ext4 support in U-Boot. Read more about it here: http://lxr.missinglinkelectronics.com/#uboot/doc/README.ext4

Best regards,
Miroslav

Hi,

We are trying to mount UBIFS, but we are getting an error while trying to mount.

We have followed the below mentioned steps while creating the ubi image.

mkfs.ubifs -r /home/sdk6/targetNFS/ -m 2048 -e 126976 -c 2768 -o ubifs.img

II) ubi.ini file contents are as shown

[rootfs]

mode=ubi

image=ubifs.img

vol_id=0

vol_size=336MiB

vol_type=dynamic

vol_name=rootfs

vol_alignment=1

vol_flags=autoresize

III)

ubinize -o ubi.img -m 2048 -p 128KiB -O 2048 -s 2048 ubi.ini

On the target board we have executed the following steps as shown:

root@am335x-evm:/# flash_erase /dev/mtd7 0 0

Erasing 128 Kibyte @ 1f860000 -- 100 % complete

root@am335x-evm:/# ubiformat /dev/mtd7 -f ubi.img

ubiformat: 4036 eraseblocks are supposedly empty
