About AM3517 ECC

Other Parts Discussed in Thread: AM3517

Hi,

I am using Micron MT29F4G08ABADA to boot AM3517. U-boot version is uboot 2009.03. And sometimes uboot could not start kernel, UART printfed 'nand read error from 0x3c0000 failed -117'. I used 'nand dump' to read nand, and found an 1bit error.

I used 'nandecc sw' to download uboot, kernel to nand. The nand's page is 512B. However, ecc.size in nand_correct_data of NAND_ECC_SOFT is 256. Does this the reason why I failed?

Could any one give me some advices?

Thanks a lot!
