Using SEGGER SystemView

SEGGER SystemView is another software tool that can be used with SEGGER debug probes. It provides a means to visualize the flow of tasks and interrupts in a system.

Unlike Ozone, SystemView doesn't have any programming or debugging capabilities, it is only a viewer.

Installing SystemView

There are two main steps required for making your system visible with SystemView. The software needs to be installed and source code must be instrumented so it will communicate its status over the debug interface.
