AT91SAM9260-EK NAND Driver error

[Fabio Porcedda]

Hi all,
I have trouble reading from the nand device driver.
I'm using the Atmel AT91SAM9260-EK board with barebox v2010.11.0,
I'm using the at91sam9260ek default config with the "Atmel (AT91SAM9xxx) NAND driver" enabled .

When I try to access the nand device I have an error:

barebox:/ md -s /dev/nand0
err -74
read: error 74

I'm making some mistake?
It's a know issue of the nand driver on the AT91SAM9260-EK?

Thanks in advance for any help
Fabio Porcedda
