I use these arguments:
nandwrite -a -o /dev/mtd0 dump.img

Is it right?

I just try this -o "no-checkpoint-read", but it changes nothing.

When dumping the original NAND with nanddump, the write size and oob size were detected as 2048 and 56 respectively. The 56 OOB size is not conventional. This is why I modify the source code of nanddump to overwrite the OOB size to 64. Perhaps is it this point which is my issue. What do you think about this?
