nand flash driver

Dear all,

I faced the nand flash driver in u-boot. After flashing the u-boot into NAND flash, I have two datas.

1. The first one is related to u-boot data which is correct . 2. The second one is the extra data that I didn't know where it was coming from.

The second data is just writing after u-boot data. Please could you tell me where this data is calculated ?

I'm using the davinci board.

Best regards, Aubin
