Hi
well unfortunately I am not deeply involved in RTLinux anymore. I haven't
even used anything like CAN or RTLinux lately (will soon change I guess :-)) )
But spin lock leads to a smp machine. Was there any change in RTLinux lately?
I have never heard about that. And btw is the card a c200 compatible one?
Sorry, I don't even have the source handy right now.
