I'm kinda surprised not to have seen discussion here of the Flash memory/OSproblems suffered by the Spirit rover. It seems noteworthy that several $100million's worth of kit was crippled for so long by what was reported as apriority-inversion issue. And you can't get much more hard-realtime than theSpirit rover.NASA have said that their biggest problem with the WindRiver OS iscomprehension. For me, this neatly underlines the problems I've had withRTOSs... and why I avoid them as far as possible.Discuss ;).Steve
