Hi,
We are using an Atmel AT91SAM9263 processor which supports 1 Bit ECC flash
devices that have Block 0 Valid with no ECC. These devices are now obsolete.
We have fitted a board with a MT29F2G08ABAEWP-E-E, which has an internal
Hardware ECC engine. Would you know how provide support for this device
within U-Boot?
The following output is generated by a board fitted with the NAND Flash with
Internal Hardware ECC

As your flash have internal ecc, you should disable the AT91SAM9263 ecc.
it means you need to set the nand->ecc.mode to NAME_ECC_NONE
in the U-Boot if you already enabled internal Hardware ECC.

Hi Josh,
That worked! Many thanks.
The next issue is that the Kernel now needs to be re-built, we are using
2.6.xx, do you have any ideas on what to change in the Kernel to make it
work with the HW ECC NAND?

If you are using the github/linux-2.6.39-at91 branch, you need change
the arch/arm/mach-at91/board-sam9263ek.c to set .ecc_mode as NAND_ECC_NONE.
