You want to run the latency test. But the latency on a system without load is meaningless. As part of validating Xenomai, we use a test called "dohell" to load the system. We provide a system to build a root filesystem for running these tests called mkrootfs, available through git: http://git.xenomai.org/?p=mkrootfs.git;a=summary It has a README which should help you generate the root filesystem. The procedure to run the test is: - in a telnet session connected to the board, run the latency test - in another telnet session, launch "dohell" - when this scripts displays "Listening on any address 5566" run netcat target 5566 > /dev/null Now wait a few hours. -- Gilles. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
