Hi,

The ECC type used is NAND_ECC_HW, defined in file
arch/arm/boards/at91sam9260ek/init.c. I program the NAND using USB and
SAM-BA. I did not find a setting in SAM-BA to change the ECC type.

Changing the ECC to NAND_ECC_NONE in the above mentioned file makes
the NAND readable and my kernel boots, but this big fat warning ;-)
appears : NAND_ECC_NONE selected by board driver. This is not
recommended !!

Regards,

Mickael
