For now, I have a simple model in xPC Target that sends/receives data over UDP. The Target communicates with the same network card used to download the model. I have another simple program (written in C++) running on the Host that streams data to the Target over UDP.

If I disable "Multicore CPU support" under the xPC Target Explorer settings, then the model works as expected. However, if Multicore CPU support is enabled, then no communication occurs (neither send nor receive). The model does run as expected in all other regards, however.

I have not found any useful documentation on this issue. Has anyone else experienced similar problems?

Aaron,

You should contact MathWorks tech support about this issue. That will
direct the issue to the correct person in our group to look into it.
There may be something specific about your hardware that's causing
the problem.
