Hi Heiko,
Thanks for your response.

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;
I tried but that did not work, it is equivalent to remove fsl,use-minimum-ecc in gpmi node I used to run ubiformat to flash UBIFS image to NAND:
# flash_erase /dev/mtd2 0 0 # ubiformat /dev/mtd2 -f /tmp/ubi.img
That caused the NAND boot error to run "ubi part" ubi_io_read: error -74 (ECC error).
Richard shed light on the problem that u-boot and Linux use different MTD settings, I figured out it is the ECC problem, while adding fsl,use-minimum-ecc in gpmi node cannot even start NAND boot. Why fsl,use-minimum-ecc in gpmi node causing such predicament?
Thank you.
Kind regards,
