Auto-Negotiation FAILED with TSEMAC and PHY Marvell 88E1111

I'm trying to check single socket example in a Cyclone III EP3c40.

I've configured in SOPC in both case:

as 10/100/1000Mbps Ethernet Only

as 1000Mbps Small MAC

result was always the same 


nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster ", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

    The problem could come from the GMII interface. Are you providing the correct clocks in gigabit mode?

    Another cause could be bad timing on the GMII signals. Did you set up the constraints on all the signals? I had to use a pll to delay the clock on the transmit side in order to meet the constraints (unfortunately I don't have the kit here, I cn't check what I did).

    Removing auto negotiation in the network card, I've set 100Mbit full-duplex and now it works.

    Gigabit is not working when I tried to set the network card to 1gbps full duplex.

    The link is established in both cases but in Gigabit never a data was received from host.

    What is strange is that on the other end it says that the interface is active, and even that it received a packet... Is auto-negotiation enabled on the PC?

    Status of LAN is :

    State: On

    Does the PC say anything about the LAN interface status?

    If you can connect an oscilloscope to the LAN connector, you can also check if you see any sync pulses going on the lines.

    there are some things you can check:

    -the MDIO communication with the PHY is working correctly? I suppose yes, otherwise it wouldnt recognize your Marvell PHY.

    -the clock signals you use with both mac and phy are with the correct freq?

    -your host PC NIC is able to auto-negotiate? maybe it worked with the 10/100, because these ones normally dont use autonegotiation.

    - I wouldnt use the 1000 Small MAC config. in the TSE, because this way your are telling him only to connect if there is a Gigabit available on the other side, and it is probable that your PC dont have it

    obviously I always connect a board to a host computer using cross crossing ethernet cable

    But do you connect the two boards together, or do you connect them to a PC?
