Re: [Xenomai-help] Very high latencies under stress testing

Thanks, this script sounds like exactly what I need. I downloaded the latest snapshot of mkrootfs from git, but I don't want to install that on my rootfs. I'd just download the script alone, but looking at it I see it would want to run a script in /ltp as well, so I guess I need ltp too. Can you tell me an easier way to set up dohell that might save me sifting through the whole of ltp and mkrootfs to figure it out?

Thanks again,

Edward
