So, this means there is no rtnet driver available for beagle bone ? Then it looks like we have to drop Xenomai for beagle bone... :-( However, I found that somebody have ported TI ethernet driver here: https://github.com/hiddeate2m/rtnet/tree/master/drivers https://sourceforge.net/p/rtnet/mailman/message/32523245/ Is it worth to try ?
