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
