Dear Matevz Langus,
Hi,
sorry for top-posting.
It is Freescale eLB NAND controller. We need to investigate a bit more why it does not work with 512B sub-pages in u-boot. It does in Linux.
And are you sure it does use 512b subpages in linux? Because I think there's still a bug in linux that forces these controllers (at least the GPMI NAND) to use 2048b subpages.
eLBC hardware does not support doing ECC on subpage accesses (and thus the driver does not support subpage accesses at all). How does UBI use subpage accesses?
