That is exactly the problem I have, the MTD layout in both Linux and
u-boot is the same:

# mtdinfo
Count of MTD devices:           3
Present MTD devices:            mtd0, mtd1, mtd2
Sysfs interface supported:      yes

Are there any ways or tools in Linux to change MTD settings (most
likely the ECC or DTB) to the same setting in u-boot? I do have mtd
and fw_setenv in Linux.

Thank you so much.

Kind regards,

- jh
