Getting a little off topic, I wonder, who are these "Ethercat folks" of whom you speak? I do know of a few open source implementations, but none are based Xenomai: * IgH etherlab This is a complete stack in the kernel. Although they claim it works with Xenomai, in fact it does not, since it uses regular kernel spin locks, etc. However, it could be adapted to work with Xenomai. * SOEM This is a user space (really simple) stack based on normal raw sockets. It could also be adapted to use Xenomai, by adding some sort of raw RT socket. * OSADL This was withdrawn because of license concerns. I never saw the code, but I do beleive it was a user space solution using standard sockets. * Another? There once was some C++ program from some institute in the Netherlands (or Belgium? can't remember), but it was also withdrawn. So, did you mean any of these, or yet another implementation?
