Task has Stalled

My application uses 9 tasks - one of which is what I referr to as a general Mananagement task. It controls time related functions.

This task is linked to the RTOS via a call to xQueueReceive with a timeout of 1.

Within the the overall xQueueReceive loop – it may also call a vTaskDelay.

This task has stopped running and my issue is I don’t know where it is. — most likely wating in a QueueReceive - which should return every tic as long as no higher priority task is running – which I know time is available since I can break into the idle task…

I can break on another task and walk it into the FreeRtos tsak manager – but I not sure the best way to see/identify where my task in question is and why it’s not running.

Any debugging advice is welcome.

Thanks.

Joe

Have you tried running with FreeRTOS+Trace?
(http://www.freertos.org/trace) You will be able to look in the time
trace view to see what the task is blocked on. Alternatively, if you
are using an IDE that has a StateViewer plug-in you will be able to see
the handle of the object the task is blocked on. Which IDE are you
using? Some have more sophisticated thread aware capabilities.
