After some disappointing issues with my XC-2, I was able to get the more "complicated" source code working. First, I had to power cycle my XC-2 several times, and when I touched the strain relief, it crumbled into several tiny pieces! I still couldn't get the XC-2 recognized in Win7, so I plugged in my XC-1A, and that worked fine. I could only get the XC-2 to come up with the USB cable from my XC-1A, so I guess the USB cable that came with the XC-2 was also defective.
The issues I had earlier with the ethernet examples were all noob related. I had to dig around in XDE to figure out how to make it find the header files needed for the ethernet server and other classes.
Once I resolved that problem and changed the IP address in the source (for app_ethernet_demo3.1v3), I was able to run the demo, but ping times were very high -- almost 200ms! I removed the printstrs and as expected, ping times went down below 1ms.
I'm going to look over the example code, but I have to say that the tutorial is lacking substance. The beginning of the tutorial is just like the one from the XC-1A, which is great for introducting non-ethernet, basic concepts. The ethernet tutorial literally says, "change the IP address", and then "make an LED blink". I'd like to see a real tutorial, like "this is how you can get a webserver running", or something similar.

Hi all,
I have two XC-2 board, but did not do anything so far with it yet.
It would be nice if somebody could supply a good link, especially
with UDP stuff, because in my case that is the intended use.
Thanks

compared to the TCP/IP stack found on github.
I have used it for UDP.
Probably not the most confused programmer anymore on the XCORE forum.

There is now a simple UDP example in the xtcp Github:

Hi,
In terms of tutorials the github version of the repositories (which have come on a bit since the 1.3 versions). Have more documentation:
http://github.xcore.com/sc_ethernet/index.html
http://github.xcore.com/sc_xtcp/
There are some worked examples in there as well which may help with using the code.
