如果设置CONFIG_SYS_NAND_OOBSIZE 为224 能识别出Nand Flash但是读写总是报ECC错误

Shine：

CONFIG_SYS_NAND_OOBSIZE 为64, 要用BCH8，请看BCH和OOB的计算关系。

您好！感谢你的回复。我现在的配置是这样：
#ifdef CONFIG_NAND
/* NAND: device related configs */
#define CONFIG_SYS_NAND_5_ADDR_CYCLE
#define CONFIG_SYS_NAND_PAGE_COUNT (CONFIG_SYS_NAND_BLOCK_SIZE / \CONFIG_SYS_NAND_PAGE_SIZE)
#define CONFIG_SYS_NAND_PAGE_SIZE 2048
#define CONFIG_SYS_NAND_OOBSIZE64
#define CONFIG_SYS_NAND_BLOCK_SIZE (128*1024)
/* NAND: driver related configs */
#define CONFIG_NAND_OMAP_GPMC
#define CONFIG_NAND_OMAP_GPMC_PREFETCH
#define CONFIG_NAND_OMAP_ELM
#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_ECCSIZE512
#define CONFIG_SYS_NAND_ECCBYTES 14
#define CONFIG_SYS_NAND_ONFI_DETECTION

#define CONFIG_SYS_NAND_U_BOOT_OFFS 0x00180000
结果跑起来就报错：

但是如果将：define CONFIG_SYS_NAND_OOBSIZE 64 改为define CONFIG_SYS_NAND_OOBSIZE 106或者更大就能识别出设备是128MiB但是用不了

Jun Xiao97：

回复 Shine:

将CONFIG_SYS_NAND_OOBSIZE 修改为106或更大就出现下面的结果（能够识别，但是读写就报ECC错误，现在的问题就是明明是64的OOB反而不对）
