As per OMAP3530 TRM referenced below [1] For large-page NAND, ROM code expects following ecc-layout for HAM1 ecc-scheme - OOB[1] (offset of 1 *byte* from start of OOB) for x8 NAND device - OOB[2] (offset of 1 *word* from start of OOB) for x16 NAND device Thus ecc-layout expected by ROM code for HAM1 ecc-scheme is: *for x8 NAND Device* +--------+---------+---------+---------+---------+---------+---------+ | xxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] | ... +--------+---------+---------+---------+---------+---------+---------+ *for x16 NAND Device* +--------+--------+---------+---------+---------+---------+---------+---------+ | xxxxx | xxxxx | ECC[A0] | ECC[A1] | ECC[A2] | ECC[B0] | ECC[B1] | ECC[B2] | +--------+--------+---------+---------+---------+---------+---------+---------+ This patch fixes ecc-layout *only* for HAM1, as required by ROM-code For other ecc-schemes like (BCH8) ecc-layout is same for x8 or x16 devices.
