Well based on the list above, the answer appears to be none of them. The cpsw is one of the weirdest network designs I have ever encountered. It is a network interface missing a bunch of standard features (like mac filtering) connected to a switch chip which is responsible for the mac filtering and such while also being a switch. It can be quite annoying to deal with. On the design I worked on we ended up using a PRU ethernet port for xenomai instead because the cpsw was just not sane to work with. Don't have that option on the beagle though. -- Len Sorensen _______________________________________________ Xenomai mailing list Xenomai@xenomai.org https://xenomai.org/mailman/listinfo/xenomai
