Thanks for the good ideas. I have now replaced the accesses to the internal thread structure (real_priority, current_priority) with API - calls. One of the calls is from the pthread-library and therefore needs --enable-posix when creating the BSP. Calls used pthread_getschedparam rtems_task_set_priority
