Thanks for the tip, actually I am trying to simply compile an ISO image to run under VirtualBox at the moment, so latencies are way down on my list. My notes are here: https://sites.google.com/site/bifferboard/Home/boards-with-1mb-flash/buildroot/xenomai It all seems like a bit of a hack, so my next task is to try to create a buildroot package to allow choosing the trivial-periodic demo and installing it from the Buildroot config menu. kind regards, Biff. _______________________________________________ Xenomai mailing list Xenomai@xenomai.org http://www.xenomai.org/mailman/listinfo/xenomai
