Well, it is an interesting question. Yes, Atom and Geode are more expensive than ARM, for whatever reasons. But an industrial board is about 1000 EUR anyway. The situation is same it was with workstations before PCs broke through. > Vendors: > > I still wonder why not a single vendor sells a Ravenscar run-time > with compiler at a hobbyist price, without support. Why a hobbyist would even look at Ravenscar? IMO, a hobbyist if not obsessed with systems programming, wants full Ada and a "normal" OS. This is quite possible to have today. And this is where Ada shines, because you can develop and test on a PC and then just recompile the code for the embedded target without any changes. At least this is the way we do it. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
