Linux with current mainline + pending GPMC/ELM patches thinks it
supports sub-page reads/writes on 2k page NAND with BCH8. This is simply
wrong. By using "root=ubi0:root ubi.mtd=nand0.root,2048
rootfstype=ubifs" in the kernel cmdline, you will get this override in
the kernel.
The GMPC NAND driver in barebox correctly does not use sub-page-access
and works fine without overriding the VID header offset.
When building the UBIFS/UBI the offset must obviously be set correctly.
Which kernel & barebox are you using?
Regards,
Jan
