Hmmmm Not completely happy with RTAI, just can't seem to get designer to work for qtvcp. If I build the packages myself from git designer is ok, but running a sim config causes the machine to freeze.
I wish Andy would chime in.....maybe he would have an answer as we need a real guru.
And regarding installing without a internet connection.
Booted and installed on VBox with the VBox LAN cable unplugged, install went smoothly. Will try on real hardware over the weekend, work has decided to give me a shift for Friday, thereby interrupting my iso creating.
