A goes for I/O . … WebMay 4, 2016 · Any two RTOS tasks that operate at different priorities and coordinate via a mutex, create the opportunity for priority inversion. The risk is that a third task that does not need that mutex—but operates at a priority between the other tasks—may from time to time interfere with the proper execution of the high priority task. rock hill movers https://fkrohn.com
