P4080: DDR:How to fix ECC error when read DDR.

Question asked by carl peng on Jun 13, 2016

During debug P4080, I encounted a ECC related issue.

If I enable ECC in the DDR paramenters, then when I read DDR, will hang.

If disable ECC, read will not cause hang, but the data is error.

My questions is how to handle this kind of issue? is it caused by unsuitable parameters of DDR or hardware design, like PCB.

Can it be resolved by configure DDR parameters? How to? Could you please help to give some suggestions?

Thanks a lot!
