Linux/AM3351: Ubifs mount issue

Part Number: AM3351
Other Parts Discussed in Thread: AM3352, TPS65217

Tool/software: Linux

To Ti experts:

Right now; we were able to bootup our AM3351 board with squashFS from NAND partition 7.

Our device has 128MB NAND and we were using SDK V03.00.00.04 for software development.

Due to the read-only for squashFS rootfs, we created another UBIFS in NAND partition-6 to store some extra data.

This UBIFS was created by Ti SDK, create_ubifs.sh.

Below is the unionize.cfg for this user_data.ubifs.

[ubifs]
mode=ubi
image=./user_data.ubifs
vol_id=0
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

We got an error when trying to mount this /dev/mtd6 to the RAM disk.

Below is the log from board bootup to the ubifs mount command.

Please, use this mount -t ubifs ubi0:rootfs /media/ram/ line.

Check this Processor SDK wiki page out, the second argument should be UBI volume name from ubinize.cfg file.

According this Memory Technology Devices site.
The modern way of mounting UBIFS is mounting UBI volume character device nodes, e.g.:

$ mount -t ubifs /dev/ubi0_0 /mnt/ubifs

I also would like bring to your attention that message which indicates that your partition calculations might not be correct:
[ 1.730283] mtd: partition "NAND.file-system-2" is out of reach -- disabled
