nandwrite does not do any data-dependent operations. It only checks the
size of the file to verify against MTD alignment restrictions, but
otherwise, it is simply a dump page-at-a-time programmer.

However, there are other characteristics which do differentiate it from
dd, so it's not surprising if nandwrite can uncover different code
behaviors than dd.

(BTW, I wouldn't recommend dd for NAND programming. It may be useful for
certain debugging purposes, but it ignore bad blocks and is generally
dangerous to use for any regular purposes.)
