Some problem in real application

[Jacky Lam]

Dear all,

I am new to UBI and want to apply it in a real production application.
However, I have a technical problem and hope anyone can give me some advice.

I use NFTL before. While in production, we use some self-made IO
programmer to program the NAND flash. We first write the data and ecc
(in spare area), and then read then back. After verify it with ECC, we
can tell whether the data is written correctly or not.

However, in UBI, it doesn't use spare area and embedded the ECC
information in main area. Will it be difficult to extract the ECC
information from the read back data in order to do verification? I am
worry about our self-made IO programmer is too slow for handling UBI.
(Or any other clever way to do that?)

If my question is not clear or even wrong, please point me out. Thanks
very much for help.

BR,
Jacky
