I tried to use rt a while ago but have not yet get rtnet up and running. I have however tried soem Ethercat master and soes Ethercat slave and they work. I run soem Ethercat master within linuxcnc. I should solder and try another board before I continue with the hardware for the Ethercat board. I discovered then using ordinary rt kernel that scheduling is good enough but then logging times of messages sent with Wireshark there sometimes is a delay of up to 5-10 milli seconds. You got rtai and rtnet up and running? > Many thanks for your help No help right now, only new questions.
