Hi,
I put a ubi image on a sheevaplug but got those errors:
uncorrectable error :
UBI error: ubi_io_read: error -74 (ECC error) while reading 512 bytes
from PEB 39:512, read 512 bytes
So I tried to use ubiformat and ubiattach but after a successful
ubiformat, I got the following error:
# ubiattach -p /dev/mtd2
ubiattach: error!: cannot attach "/dev/mtd2"
error 25 (Inappropriate ioctl for device)
I've never seen this and google doesn't help much. I could flash a jffs2
image w/o problem.
Does anybody have a pointer != NULL ?
Cheers,
David.

What happens if you do ubiattach -m 2 instead, i.e. specifying the mtd
number rather than the complete device path?

I also tried
ubiattach /dev/ubi_ctrl -m 2
but it didn't change anything

This probably means you are using too kernel where UBI does not support
this ioctl. Dynamic attach / detach were not part of the initial UBI
which want into the kernel, AFAIR.

Please, run mtd tests on your device and validate your flash first:
