TCP/IP stck for Ethernet applications on MCF5234BCC?

net11 — Sun, 16 May 2010 07:53:18 GMT

Hi,

I will be working on building an Ethernet application on Codewarrior for the MCF5234BCC KIT. I have been suggested to use the Interniche Lite. Does Interniche have a version for the particular board that I am using ? Where can I find the software and the documentation ?

Also, since I am working on an Ethernet project for the first time, I will probably need a lot of help and clear documentation. Does anyone suggest a better(easier to learn) stack to work with for newbies ?

Even though I use Interniche Lite myself, I would suggest not to use it. It's kinda buggy and it hasn't been updated by Freescale for more than a year now. The official version isn't compatible with the latest version (v7.2) of Codewarrior either. Also, there's no support for the MCF5234 CPU in Interniche Lite, although it shouldn't be too hard to adapt it.

In case you still want to look into Interniche Lite, I have made my own package that contains some fixes for bugs that I found and some functional improvements. I have also made it compatible with Codewarrior 7.2. You can find my version here:

Hi Marc,

Thanks for the links to the code. Also thanks for letting me know about what to be careful about while using the Interniche stack. What I need to do is much simpler than using the functionalities of the complete stack. For now, I just need to be able to send a packet from one board to the other and vice-versa. Later I intend to build on this. I figure I need to learn how to work the FEC for this. Two specific questions :

Which files (in the stack patched by you) do I have to look at to be able to achieve this simple task, and which won't be necessary to look at?

How to run this code on my board?

It is very hard to say which files are required and which aren't because there are a lot of dependancies.

Maybe you could also look into the FNET - TCP/IP stack. There's a thread on this subject, see:
