Please do you have any results in your troubleshooting the DP83848C PHY connection? I am having the exact same problem and I can see the data packets on RX[3..0] lines, also the RXDV signal is OK. What I can not see is any response on the TX[3..0] lines or TXEN. TXCLK, RXCLK are fine also. The link status is also OK, I have the very same console output as you on the top of this thread.

Have you solved your issue? Do you have any recommendations what to try,.. or?

Thank you very much for the reply...
