Hi,
I am working on NAND flash driver on TI's OMAP based board.
NAND is large page nand with 8bit buswidth.
I need to calculate ecc for the spare area data.
1.Does the current linux nand driver support ecc calulation for spare area
with hw_ecc/sw_ecc enabled?
2.If not could any one suggest on what data of the spare area info I need to
calculate ECC?
I am a begineer working on MTD driver. Please provide your
Valuable comments.
Regards,
-Sameer

It depends on the driver. which processor are you using?. You
could either use
software to generate ecc or use the hardware to generate the ecc.

ECC is computed for the data that is stored in that particular
page of the flash.
ECC and other information like bad block is stored in the spare area.
