Neither UBI nor UBIFS care about ECC. The MTD stack does. If you write something in Linux you cannot read back in u-boot a common problem is that u-boot and Linux use different MTD settings (layout, ECC, etc...).
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.
No for U-Boot (as I am aware of). You need to fix the DTS or may if older U-Boot your code.
May you need to add in your U-Boot DTS gpmi node the property:
fsl,legacy-bch-geometry;
?
see commit:
51cdf83eea - mtd: gpmi: provide the option to use legacy bch geometry
