You can also use headless mode to trace a target device using just the target-side components. The main difference between using the host and target-side headless modes is where the trace output is stored. Host-side headless mode can only save traces to the host machine, and target-side headless mode can only save traces onto the target device. The interfaces for each headless mode are also slightly different. For more information, see 5.23 Target-side headless mode.
