Need help on custom UBIFS creation

Hi,

Please check this wiki and links from it: http://processors.wiki.ti.com/index.php/UBIFS_Support

Thanks Biser. We are following the same links and generated the new ubifs.img with mtb-utils and ubinize.cfg with mkfs.ubifs command
but the system is crashing .
We given rootfs path is :SDK-08/filesystem/arago-base-tisdk-image-am335x-evm (which is an untar file).

1. We like to verify the commands with TI technical team.
"mkfs.ubifs -q -r root-fs -m 2048 -e 126976-c 2047 -o ubifs.img " -- is that calculation right or wrong.

2. Back trace for the kernel panic/crash dump:

Please help us in this.

regards,

Vijay.

Hello Vijai,

The vol_size=240MiB seems doubtful, could you change it to vol_size=200MiB then check the result.

Best regards,
Kemal

Thank you. I have already made a change and still it doesnt work.
Here is my ubinize.cfg file :
[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=100MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

I have also used -F flags, but still not luck. There is a crash. The Nand chipset I am using is : MT29F2G08ABAEAWP
Thank you

Hi,

Thank you for helping us. It worked.

Totally we made three changes .As suggested by Kemal R. Shakir, we have changed the

vol_size=200MiB in ubinize.cfg file

and we made subpage size equal to 2048 instead of 512. 

sudo ubinize -o ubi.img -m 2048 -p 128KiB -s 2048 ubinize.cfg (sub-page size we made equal to 2048 instead of 512) .

To create a ubi.img, we made use of -F flag in the below command.

sudo mkfs.ubifs -F -q -r rootfs -m 2048 -e 126976 -c 2047 -o ubifs.img
