After a couple of hours of work porting the enc26j80 driver from my own mini ipv6 stack to uip, I have my enc28j60 booster pack working with the Stellaris Launchpad.
The current example code is at https://github.com/xpgdk/stellaris-enc28j60-booster and does nothing more than acquiring an IPv4 address and serve a static web-page on port 80. The code is tested using GCC only.
(I apologize for the quality of the video)
I will be improving the driver and the example code in the coming weeks.
