Hi, Is it possible to have something like: int main() { vTaskStartScheduler(); . . // some task calls vTaskEndScheduler();

             .
  vTaskStartScheduler();
                  ..
                  ..
  // some task calls  vTaskEndScheduler();

} in an application? That is, after an application calls vTaskStartScheduler and then a task calls vTaskEndScheduler, can the application call vTaskStartScheduler again? We are performing a static data race detection and data flow analysis on FreeRTOSv10.0.0 which assumes that such a situation will never arise. Is our assumption correct or not? Thanks, Nikita

Very few ports implement vTaskEndScheduler(), perhaps only the Windows and DOS ports. I think in the Windows case ending the scheduler terminates the process, so code after vTaskStartScheduler() will never run. I can’t recall what happens in the DOS case as the port is about 15 years old but I think FreeRTOS replaces DOS in memory and then uses a setjmp/lngjmp pair to exit the scheduler – not sure where it goes from there though.
