This is the third time you post this incomplete report. See: http://www.xenomai.org/index.php/Request_for_information If you want to receive an answer. Because in xenomai 2.5 branch, each process maps a shared memory when starting. So, if shared memory were not working, no xenomai process would work, not even the latency test. -- Gilles. _______________________________________________ Xenomai-core mailing list [email protected] https://mail.gna.org/listinfo/xenomai-core
