Hi Stephane,
On the user side, I was just calling some simple functions which I defined
to do some repetive work. On the RT side, I just have one periodic task
running,
which does a pthread_wait for the next period.
I have now found that the user side seems to hang at other times. Its pretty
random though. I believe it
all has to do somehow with interrupting X calls. Do you have any experience
with
running X under rtlinux? I have work with X many times in a non RT
environment and
have not had these problems. Is there a better alternative to running X for
doing graphical
stuff under RT linux.
Any info would be appreciated.
