eth0 device not found

I am running a uClinux kernel (2.6.16) from DDR2 SDRAM on an Altera Cyclone II DSP Board. I have a Microtronix USB/Ethernet daughter card connected.

I enabled the Davicom DM9000 ethernet and TCP support in my kernel configuration.

I am using a crossover ethernet cable to connect the board to a laptop. The LED on the ethernet daughter card does not light (indicates that there is no link) and the laptop does not recognize the ethernet connection ("Network cable unplugged") (firewalls are disabled).

I am able to ping the ethernet card from the Altera board in a local loopback.

I can change the ip address when referencing "lo" (What is lo?) but recieve errors ("no such device") when referencing "eth0".

The following is bootup and the commands i have tried:

What have I missed? How can I connect to the Ethernet card?

    According to other posts and tutorials I have found, I have added DHCP support to my kernel. I also placed the DM9000 on a seperate tristate bridge in the SOPC builder.

    Still I have not been able to connect to the ethernet card...Anyone have any ideas???

    Maybe you have to add the correct ethernet drivers to the kernel. Someone similar happened to me before adding them. Yo have to go to kernel configuration, and then device drivers, Network device support. I don&#39;t know which eth driver will suit your eth device. Mine was Ethernet (10 or 100Mb) -> SMC 91111.

    I am using the Microtronix USB/Ethernet Daughter Board which has the DM9000 ethernet chip. So I have added Ethernet 10/100Mbit , Davicom DM9000 10_100 Ethernet chip support in my kernel.

    --EDIT--

    Although I have added the DM9000 support in my kernel I am not seeing the driver during bootup. Shouldn&#39;t I see it sometime in the boot script? Is there a step I&#39;m missing?

    shouldn’t there be a DM9000 driver or something that references DM9000 about here???

    I think dmfe_probe has something to do with your DM9000 driver. In my system, I have smc_probe (which has to do with DM91111) and after:

     SMSC LAN91C111 DRIVER 
     eth0: SMC91C11xFD (rev:1) 
     NET: Registered protocol family 2

    So it seems that dmf_probe does not succeed looking for devices ... ¿?
