Jon,
Thanks for you suggestion, yes I will post a new thread on this problem, cause right now most the problem I met were related to hardware, my custom board have 1GB DDR3 as 8168evm board, same configure with the interface EMIF0 AND EMIF1, I did the memory test before booting into Linux, no error while reading and writing the memory, so, that might not be the problem, I still waiting for the rest of my protocol boards, I am not sure right now if this is a common problem on my design, hope that is not, anyhow, thank you so much, have a good night~
Warm regards,
Kevin
