Driver for Opencores 10/100 Ethernet MAC

Question

Where can I find the driver for Opencores 10/100 Ethernet MAC?

altera_forum · Answer

What network stack/OS are you planning to use?

A couple of years ago I ported this MAC to work with Nios I and the plugs library. I can post this code but it won't be compatible with LWIP or linux -- some work would be needed to port it.... however it wouldn't surprise me if others here have done such a port or written a new driver from scratch already. Let me know if you're interested.

Hello yaoli

I have written a driver for the Opencores MAC 10/100 and used it to generate a lwip webserver project. Unfirtunately, I don't see how I can add an attachement to this post, so I'll try to send it to you somehow.

The Opencores 10/100 Ethernet MAC seemes to be supported by Linux. You will find it in the kernel configuration, among with some other network device drivers.

Hello,

I had successfully generated the system in Verilog, but in software compilation I found this errors. For now, I'm compiling a "Hello World" example, which don't require any network resource.

Thank you!
