tse_mac with dp83848 phy in MII interface

Hi

I am trying to make a design with a triple speed ethernet MAC from Altera work. I am using a National DP83848 PHY and the small 10/100 version of the MAC.Currently I have this problem:

when I run the nichestack init, I get this output:

at the same time DP83848 is very hot?

Could someone give me the golden tip to get this running?I would really appreciate your reply!

    Actually you're printout is exactly as it should be. I don't see anything amiss at all.

    Other than your DHCP timeout. Is it supposed to be getting the IP address via DHCP (you have it connected to a DHCP server)?

    You might consider changing the static IP address from 0.0.0.0 to something useful.

    this " IP address of et1 : 0.1.1.102" why is it different from what i defined?

    There is a bug in the macro that converts the defines to an IP address. I think some parenthesis are missing. There is a thread about that in the Nios forum.

    You should install something like Wireshark on your PC to see what is sent and received on the Ethernet link. Then use some SignalTap probes on the MII interface to see if the packets are correctly sent/received.
