I saw one reference for lwIP (http://savannah.nongnu.org/projects/lwip/) in this forum.
Anyone trying to make a port?

Thanks. Regards, Arjan

Given that IP runs, by necessity, over USB on the Pi, it's gonna have to wait until there's a fully working USB implementation up and running.

Actually, LWiP does not need usb.

The only thing LWiP needs is a way to pass on and receive bits. the fysical layer doesn't matter.

You can use for example GPIO to send the ethernet packages to another RPi.

Hi Joris,

The Ethernet controller used on the Raspberry Pi is connected to the SoC via USB. So I really need to wait for full USB implementation.

Grt, Arjan

Oh well , i'd be interested in Ethernet over GPIO :D
Where would be the technical speed limit on that ?

• Don't like the board ? Missing features ? Change to the prosilver theme ! You can find it in your settings.
• Don't like to search the forum BEFORE posting 'cos it's useless ? Try googling : yoursearchtermshere site:raspberrypi.org

Ethernet over GPIO, has some one be thinking about the Xerox Alto:-) ? That is definately doable . Heck if we are delving into sof hardware what about VGA over GPIO?
