idle task not number 0 in vTaskStartTrace

Posted by Chris on May 26, 2011
Does it make since for the idle task to not show up as number zero as stated on the FreeRTOS site? I create two tasks and then start the scheduler. When I do a task trace the results were very puzzling at first. I've confirmed the ordering by using vTaskList.

The idle task is the last task to be created (unless timers are also being used). I would therefore not expect it to every have a task number of 0.

Originally, in very old versions of FreeRTOS, the idle task was the first to be created. Then, it would be number 0. I suspect the web page you are referring to was correct at that time, but is no longer correct. I would be grateful if you could post the URL of the offending page so I can ensure it gets updated. Thanks.

Just below the task chart.
