hello, Thank you for helping me solve my problem.
You recommend me to update to a more recent version. But I think the xenomai version 2.6.0 is the lastest version over http://www.xenomai.org site. By the way, i have a short question. When i make run cross-link program, i don't understand why there is a leak memory. Even if, i try to remove all parasite in while loop, but the leak memory is always constant. i think the problem comes from rt_dev_write() or rt_dev_read() which don't release the memory buffer. im wrong?
