I am afraid your board is none of them. I doubt your board is not=20 correctly configrated with some timing or signals. The key issue (i want to emphosis ) is that the current gpmi-nand does=20 not support the subpage operations. > Here the infos for our NAND device: > > [ 0.917552] ONFI param page 0 valid > [ 0.921053] ONFI flash detected > [ 0.924206] NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micro= n MT29F4G08ABADAH4), 512MiB, page size: 2048, OOB size: 64 > [ It's a SLC ,or a MLC? thanks Huang Shijie
