Hi Gents,

I am facing an issue with ubiattach on Linux kernel 3.0.8
On our target we have nand flash with mtd layer on top.
The logs attached below.

Can you please give me a pointer?


/bin # ubinfo -a
UBI version:                    1
Count of UBI devices:           0
UBI control device major/minor: 10:62

/bin # ubiformat /dev/mtd5 -y --vid-hdr-offset="2048"
ubiformat: mtd5 (nand), size 511705088 bytes (488.0 MiB), 3904 eraseblocks 
of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes
libscan: scanning eraseblock 3903 -- 100 % complete
ubiformat: 3904 eraseblocks have valid erase counter, mean value is 3
ubiformat: formatting eraseblock 3903 -- 100 % complete

/bin # ubiattach /dev/ubi_ctrl --mtdn=5 --devn=0 --vid-hdr-offset="2048"
ubiattach: error!: cannot attach mtd5
           error 25 (Inappropriate ioctl for device)


Best Regards
