StarterWare "enet_echo" example

Hi,

I use "enet_echo" example to test Ethernet but I don't have PHY into my board. Instead of my emac communicates directly with FPGA.

Can I use this example by doing some modifications? If yes, what are these modifications? It's just to test functionnality of this one.

Is there another example to use without PHY?

Thanks

My board : cpu4 (custom board based to omapl138_lcdk)
