FreeBSD would embed reasonably well. You're not to specific about your application, so it's not clear what your platform is or what operational requirements you have. > A friend has turned me on to FreeBSD, and I'm wondering if > anyone has experience in embedding this OS, and in working > with the Mach lites extension. You've already heard from Peter Dufalt; I've done a reasonable amount of embedded work but none with FreeBSD. > QNX or OS9 seem to offer most of what I need, but the > light weight thread possibilities as well as the > avialiable tools make FreeBSD a potentially more > attractive choice. Be sure that you actually need a full operating system; a few other things to consider would be RTEMS (portable realtime executive, see ftp.cygnus.com for a lot of embedded stuff), VxWorks (Wind River, they have some _very_ nice tools, but very expensive), PSOS+ (used by a number of military projects around here) and perhaps surprisingly OS/2. > Thanks for any information you can provide. Some more specifics might be handy; you say "navigation/charting", are we talking GPS-onscreen-map-and-CDROM-database? or just an overpowered compass? For such a mission-critical application, it's always worth remembering the KISS principle. > Paul Bugni. -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] "Who does BSD?"
