Hi Philippe, Why do you say that I try to grab the mutex from non-xenomai thread context ? During porting we had written main() only this main function does pthread_create to call the very first function of VxWorks code which inturn does taskSpawn. All the taskSpawns has to go through Xenomai thread context right ?

You are trying to grab the mutex from a non-Xenomai thread context.
