UBI/UBIFS error

Dear

 

I have several questions regarding UBI. I'm getting following error when trying to attach to an UBI device (u-boot):

> ubi0: attaching mtd1
> UBI init error 22

 

I got this error after programming the board with (kernel, in user space):

# flash_erase /dev/mtd0 0 0
# ubiformat /dev/mtd0
# ubiattach -m 0
# ubimkvol /dev/ubi0 -N kernel -s 32MiB

# ubimkvol /dev/ubi0 -N rootfs -s 128MiB

 

However if I first apply

> nand erase.chip

in u-boot, the programming succeeds and I don't get an error in  u-boot.

 

What could cause this issue? Could this be related to the ECC?

 

Furthermore, how can I verify the ECC mode in kernel and in u-boot?

 

Best regards

Pieter Cardoen
