lwIP

Altera_Forum · ‎12-23-2013

Hi to all,

I have an Altera DE4 development and education board.

I'm trying to implement an UDP client on my board.

To do this, I tried to follow this guide (http://www.freertos.org/interactive_frames/open_frames.html?http://interactive.freertos.org/forums/216314-altera) to use the lwIP TCP/IP stack. When I build project, the console output is the following:

Why it gives me these errors? I have not changed the code.

Please could someone help me?

Best Regards,

Umberto.

For one thing, you haven't defined TSE_MAC_BASE in your Qsys system (this is one of the things the error messages are telling you). You also might want to track the GIT source (https://github.com/engineeringspirit/freelwip-nios-ii) for this project as it appears there have been recent changes (up to around a month ago).

You should be posting the issues you have to that Github project as well.

Cheers and Good Luck!
