vtaskdelay blocks my task indefinitely

Hi vTaskdelay API is blocking my task indefinitely . I have inserted vTaskDelay( 1 ) ; in my code and the task gets suspended. I know that the tick ISR is getting generated still this wont work , what could be the problem ?.

Have you tried whether vTaskDelay(100) works (or any number greater than 1)  – ‘1’ means 1 TICK – this is generally not useful as the time taken to enter and exiting the function may be approaching 1 TICK anyway Try a bigger number report back. HTH Ivan Vernot

Hi Ivan , Tried with 10 , still the same problem . The problem could be that I am working on the Skyeye simulator for Samsung S3C4510 processor and not the real hardware. Also, I have observed for the simulator that one tick takes a long time to elapse . I need to check on the hardware shortly. Regards

If you are sure the tick is still running then check also for stack overflows.  This is the most common cause of problems. http://www.freertos.org/Stacks-and-stack-overflow-checking.html http://www.freertos.org/uxTaskGetStackHighWaterMark.html Regards.
