Hello : For those of you who tried/looked at the rt_tulip.c written by Alex Bernal -- does anyone gets the workstation that is a receiver hanging after 1-2 seconds of receiving packets? Any ideas why does this happen ? Another question that I have is -- how to determine what critical sections are in a rt_application? How do I know that this operation should be done without interruptions? I know this question is way too general, but may be, someone could give me hints.
