Just stable releases. There are no "stable releases" of Linux any more. Active development is being done in the "stable" tree. There are no more stable and development versions of Linux like there used to be. > I guess, you are not from the world of the commercial products > development. On the contrary, we are all from the world of commercial products development. That's what eCos is used for: developing commercial products. I've been using eCos to develop commercial products for 7+ years, and the lack of "releases" hasn't been even the least bit of a problem. If you feel you're not capable of working from a CVS repository and really want a "released" version, then that's what eCosPro is: http://www.ecoscentric.com/ecos/ecospro.shtml > The considerations here are a bit different than that in the > world of open-source software community.

MMU usage is Ok in real-time if you use it properly (no > page swapping, page locking, etc.). Perhaps one of those RTOSes will meet your privilege management requirement better than eCos. -- Grant -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
