Intellectual 880 points

Part Number: AM3352

Tool/software: Linux

Hi all,


We are using AM3352 Soc in Our board.

- I have query in NAND flash ECC Error calculation, in GPMC Interface we are configured 8-bit ECC (BCH) and NAND flash (SAMSUNG - K9F1G08U0D) Support 1-bit ECC only.

1) Question :1 - If i read data from NAND flash, who Calculates ECC either  1-bit or 8 - bit ECC  and correction 1-bit or 8-bit ECC (i.e GPMC or NAND Flash)?.

2) Question :2 -  If any Error Occurs who is take care to correct that errors either NAND flash or GPMC interface (Configured GPMC is 8 bit ECC and NAND support 1-bit ECC) ?.

Regards,

Vamsi.
