4 bit ECC on AM335x

If I use the ECC on the AM335x , what is the latency for 4bit ECC and are there any advantages to going higher than 4 bit ECC using NAND flash in my design.  Thank you.

    Hello,

    I am not sure if we have numbers that compare the latency of 4b ECC vs no ECC, but since the Error location is handled by the hardware, I don't think there is a very large impact on this. 

    There is no need to use higher ECC than is required by the NAND device because the NAND manufacturer guarantees no more than the required ECC amount for the life of the NAND.  If the NAND you are using requires 4b ECC then I would just use 4b ECC.
