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?
