AM3352 Kernel Failure to Locate root in UBI Filesystem

Hi,

Please let us know how have you created the ubi.img file, including the ubinize.cfg file.

Can you also try putting a VID header offset of 2048 in the kernel bootargs. Example:

ubi.mtd=7,2048

Here is how to create the UBIFS image: http://processors.wiki.ti.com/index.php/UBIFS_Support#Creating_UBIFS_file_system

Best regards,
Miroslav

Miroslav,

Thank you for the quick reply.  I created my file system using both the mkfs.ubifs and ubinize tools.  I had to recompile the tools in order to gain access to the -F option.  I started off with a vol_size of 1011744768 bytes, but received error from the kernel complaining about running out of room.  So for now, I changed to 200MiB, which removed that issue.  I've attache my calculations to this post.  I'll try the VID header offset of 2048 as soon as I get back to my development machine.

mkfs.ubifs  -F -r rootfs -o ubifs.img -m 2048 -e  126976 -c 7968 -v

ubinize -o rootfs.img -p 131072 -m 2048 -s 2048 -O 2048 ubinize.cfg -v

ubinize.cfg
[ubifs]
mode= ubi
image= ubifs.img
vol_id= 0
vol_size= 200MiB
vol_type= dynamic
vol_name= rootfs
vol_flags= autoresize

Miroslav,

I just returned to my development machine and modified boot args to apply VID header offset of 2048.  No change in the boot outcome, though.  

Thanks,
Jason

Miroslav,

I modified fstab, rebuilt the file system, and reapplied.  Do you see anything else of concern in my fstab?  The kernel still seems to be having issues loading that directory.  I modified the banner file to see if the kernel could see any of the file system, and it does print out the new banner.  

Thanks,
Jason

Hi,

I am also using the same S34ML08G2 NAND flash in our AM335x platform. I am able to see the NAND detection in my booting log.

When i tried to write images to NAND under U-boot mode it is giving the below Error.

U-Boot# nand erase 0x0 0x20000

NAND erase: device 0 offset 0x0, size 0x20000
Skipping bad block at 0x00000000

OK
U-Boot# nand write 0x82000000 0x0 0x20000

NAND write: device 0 offset 0x0, size 0x20000

Please let us know using this S34ML08G2 nand how to flash the MLO, U-boot, uImage & filesystem. Could you send us the steps to follow the same procedure in my customized board.

I am using TI U-boot SDK6 version, Linux 3.2 Version from SDK6. Please help me how to overcome this issue.

Thanks,
