Hello, I am using the latest YAFFS and MTD tarballs on a 2.6.10 kernel on ARM1136. My board has a Samsung NAND device with hardware ECC enabled. The YAFFS write verify always fails. The dump shows that the ECC bytes (bytes 6..10) are in cause: Verify failed: Addr s0 data: 0x0000: 00 00 d0 ff ff ff f0 d6 8c ff ff ff 05 01 d8 c1 Addr s1 data: 0x0000: 00 00 d0 ff ff ff c3 fc f0 65 02 ff 05 01 d8 c1 Do you know what is the cause of this problem ? I checked that ECC and VERIFY are enabled in the config, that the oobinfo structs are correctly filled in. Any thoughts ? Kind regards, Jean.
