I use these settings (
#define CONFIG_NAND_OMAP_ECCSCHEME OMAP_ECC_BCH8_CODE_HW
#define CONFIG_SYS_NAND_BAD_BLOCK_POS NAND_LARGE_BADBLOCK_POS
#define CONFIG_SYS_NAND_ECCPOS { 2, 3, 4, 5, 6, 7, 8, 9, \
10, 11, 12, 13, 14, 15, 16, 17, \
18, 19, 20, 21, 22, 23, 24, 25, \
26, 27, 28, 29, 30, 31, 32, 33, \
34, 35, 36, 37, 38, 39, 40, 41, \
42, 43, 44, 45, 46, 47, 48, 49, \
50, 51, 52, 53, 54, 55, 56, 57, }
#define CONFIG_SYS_NAND_ECCSIZE 512
#define CONFIG_SYS_NAND_ECCBYTES 14
Currently, i can read/write/erase the flash successfully. But in our custom board, we'll replace this flash with new one(MT29F2G16ABAEAWP-AIT). Both size and bus width are the same, but the vendor says the old one use 1-bit ECC algorithm, and the new one use 4-bit ECC algorithm.
According to my setting, i am using OMAP_ECC_BCH8_CODE_HW, which mean up to 8 bits error correction.
So, should i modify setting to fit this new flash?

Shawn
