How to instrument your favorite RTOS kernel to display real-time task switch activity?


August 4, 2021

One of the important features of an RTOS used by an embedded system is that the kernel manages separate tasks as if they were independent, complete programs running on the processor. A natural result of this is the fact that each task is switched on and off as the RTOS kernel sees fit, making the task itself unaware of when it is not running on the CPU. Being able to observe this task switching behavior, which is only visible to the RTOS kernel, can be invaluable in debugging incorrect behavior caused by interactions between the different tasks running in a system.

In this on-demand webinar, you will learn how to instrument your code, with very low overhead calls, so that accurate graphical displays of task switch activity can be displayed in real time.
