![]() On a board with an i.mx28 and a Micron MT29F4G08ABAEAH4, Linux says: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron MT29F4G08ABAEAH4), 512MiB, page size: 4096, OOB size: 224) the ECC strength is 16. root@(none):/sys/devices/virtual/mtd/mtd0# for i in ecc_strength oobsize subpagesize; do echo $i = `cat $i`; done ecc_strength = 16 oobsize = 224 subpagesize = 4096 The ECC strength was not properly discovered by U-Boot causing the data written by Linux to return an -74 (EBADMSG) when read from U-Boot. This patch fixes mxs_nand_get_ecc_strength() to function in case of a NAND flash with page_data_size = 4096 and page_oob_size= 224.
