I worked on some echosounders a few years ago that were bare metal, and before that some power management equipment. Though if I was doing it again I'd probably have a bare-metal chip running the timing critical, and throw a cheap arm core on there running linux just to make life easier. And I'm pretty sure I could probably do away with the bare-metal and just pin some userspace code to a core and it'd work just as well. Edit: *'days' -> 'years'
