I managed to compile Xenomai for Ubuntu 10.10, but it did require many more steps, than you have documented so far. I documented my approach here: http://www.kieltech.de/uweswiki/Xenomai The two main problems, that remain are: 1. The clocktest program sometimes shows a time offset of +- 500 =B5s, bu= t this problem disappears by itself after some minutes. 2. The minimal and average time, that is measured by the latency test is sometimes negative (-1 to -2.2 micro seconds). Any suggestions, how to tackle these problems?
