ubiattach issue

[Dimitar Penev]

Hello Vikram,

Let me explain some more in details on my issue:

We have custom Blackfin based board running uClinux (using kernel 3.0.8)
and using mtd-utils (nanddump 1.4.6).
On this board we are using the Blackfin  platform nand driver.
UBIFS is working OK on this board.

Now we have another custom board also based on Blackfin CPU but this CPU has 
a hardware
nand controller which we have used to connect to our nand chip.
Under u-boot this driver seems to work fine and we can read/write on the 
nand flash without issues.
On Linux we are using the same  uClinux (using kernel 3.0.8) and mtd-utils 
(nanddump 1.4.6).
This time we get:
/bin # ubiattach /dev/ubi_ctrl --mtdn=5 --devn=0 --vid-hdr-offset="2048"
ubiattach: error!: cannot attach mtd5
                 error 25 (Inappropriate ioctl for device)

The difference between the two boards seems to be the fact that the second 
board is using the hardware nand controler
and the corresponding Blackfin Linux driver.

I don't see anything in my system logs related with ubiattach so I guess I 
have to enable some debugging in the kernel.
Let me recompile and try again.
If you want me to test something specific I will appreciate your advices.

Thank you.
Dimitar
