Hi,

Can you use power on setting to set block size=2k, ecc=4 and test again, thanks.

that issue conditions is that set power on PA6/PA7 pin connect to earth for 2k page size,and pa8/pa9 BCH pin opened.

Hi,

I think the reason is because NuWriter tool and IBR (internal boot rom) treat this NAND as 2k+64 while u-boot (and kernel) can correctly identify it as a 2k+128 page size NAND. So while u-boot loads the kernel, it sees ECC un-correctable error and abort. But this issue should be fixed in c7a30813.

Are you testing with HEAD version of this repository?

Sincerely,

i am just download it from repository with the lastest version at 16/03/2018. NuWriter have need update?

[yachen]

Hmmm. If you use latest NuWriter, please set power on setting to 2K page size and ECC 12. Latest NuWriter does not support set page size only because IBR (Internal Boot ROM) doesn't support ONFI and setting page size or ECC only will confuse IBR for certain NAND types.
