IDK Andy. Has the current rtai kernel been tried on stretch? Nah, its 32 bit, claims PAE but is not. Stretch is 64 bit. > If that is the case then perhaps it is time to abandon RTAI > altogether? Might be, I have only 1 preempt-rt versions running here, not on software stepping though, both on mesa cards, a 7i90HD+3 ea 7i42TA's running the Sheldon, and the 5i25/7i76D running the G0704. But I've not changed the kernel on the 6040, that machine WAS formerly softstepping the old HF micro so its still running the live iso's kernel. But I've no clue if software stepping would run on it. If I software step it, it would be buckets slower, 10 ipm or so rapids, where its doing 200 now. And I'd have to share all my home switches for lack of i/o. I hope at the end of the day, that we don't have to abandon software stepping as thats the lowest cost entry point. But for my uses, today I'd have to figure on at least a 5i25 as a driver card, and that unavoidably raises the entry bar for new users by what, 80 bucks? A sad state of affairs. Your call.
