It is the way to go, if you want to run OSEK over Xenomai. Note that the OSEK API is really lightweight, so going directly to an initial implementation of this API would take somewhere around two weeks to someone who knows the job. There is no need to turn around the problem and ask useless questions, if something is missing, you can add it to Xenomai core. > We just want to compare the tasks from OSEK and the one from > Xenomai (version 3 is preferred).

The Alchemy API is an API equivalent to the OSEK API. This is not what you should be looking at, if you want to implement an OSEK skin. You should look at the implementation itself, not the Alchemy API. > Especially a conceptual description how Xenomai sees tasks, > e.g. which states are available, when are transitions firing? There is an explanation of all this in Xenomai white paper. Have you not skimmed all the available documentation at: https://www.xenomai.org ? Please do not top-post. Regards. -- Gilles.
