Hi Marcio,
This is not u-boot related, I think you should post this
issue to
Linux kernel mailing list.

I check the
NAND flash spec and find you may use wrong
parameters for generating
UBIFS image.
--->8--- Page size x16: 1056 words (1024 + 32
words)
and no sub-page.
So, I think mini I/O unit should
be 1024 x 4 = 4096 Bytes
uncorrectable error : uncorrectable
error
: uncorrectable error : uncorrectable error : UBI
error: ubi_io_read:

from PEB 2:

This is ECC error, I think
you should also update
the driver for atmel_nand.c (mainly ECC
layout)
