thx for this hint. Unfortunately the patch didn't work for me. What does
your gpmi device node look like?

I write my NAND with mfgtool which runs 4.1.15_1.0.0 kernel during the
flash operation itself.

But on first boot it starts 4.9.18-fslc and on reading I got these ECC
errors. So it's quite possible that the ECC strength is different
between both kernel versions.

Furthermore the gpmi-nand driver has major changes between both kernel
versions.

Best Regards,

Oliver
