I attach files. That is screen captured files about serial debug data; That command 'ifconfig' with connected LAN. 'Function.jpg' is SABRE BD and 'Malfunction.jpg' is my designed Bd.

I'd like to know why figure differnt serial data about SABRE BD and my designed Bd.

Is that have recommanded PCB layout rules about LAN devices?

Please, Inform me about that question,ASPS.

Best Regards,

Inho Jeon.

Hi, igor.

Thank you for your reply.

You mean PCB lines of  i.MX6DL to AR8031(Ethenet CTL IC) about TX & RX

more shorten and same length & width like DDR3 Memories, is that right?

And, my problem on July 13,2016 is due to wrong about PCB routing patterns of TX & RX between i.MX6 and AR8031,is that right?

Plz, Reply that my questions, ASPA.

Best regards,

Inho Jeon.

Hi Inho

you should provide TskewT parameter by proper board traces routing

(using proper traces length).

Hi Inho,

yes we have hardware Development Guide http://cache.freescale.com/files/32bit/doc/user_guide/IMX6DQ6SDLHDG.pdf . In chapter 12 is described RMII interface, connections, etc.

Hope it helps
