The Tracealyzer needs to know quite a bit about the RTOS. Currently versions are available for FreeRTOS, OpenRTOS, SafeRTOS, RTXC Quadros, and On Time RTOS-32. Prices range from $2k for the most capable version to free for a stripped down product useable with FreeRTOS.

Our applications are getting more complex all of the time, but tools like these make it easier to peer inside the code's behavior.
