2 NAND Error-correction Code8 Having looked at the linux mtd/nand Hamming software ECC engine driver11 After that the speed was increased by 35-40%.22 NAND flash (at least SLC one) typically has sectors of 256 bytes.23 However NAND flash is not extremely reliable so some error detection31 As I said before the ecc calculation is performed on sectors of 25641 Back to ecc.63 - cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.69 - cp2 is the parity over bit0, bit1, bit4 and bit570 - cp3 is the parity over bit2, bit3, bit6 and bit7.[all …]
