Overview
|
|
********
|
|
|
|
The tracing feature provides hooks that permits you to collect data from
|
|
your application and allows enabled backends to visualize the inner-working of
|
|
the kernel and various subsystems.
|
|
|
|
Applications and supported tools can define empty macros declared in
|
|
:zephyr_file:`include/tracing.h` that are called across the kernel in key spots.

SEGGER SystemView Support
|
|
*************************
|
|
|
|
Zephyr provides built-in support for `SEGGER SystemView`_ that can be enabled in
|
|
any application for platforms that have the required hardware support.
|
|
|
|
To enable tracing support with `SEGGER SystemView`_ add the configuration option
|
|
:option:`CONFIG_SEGGER_SYSTEMVIEW` to your project configuration file and set
|
|
it to *y*. For example, this can be added to the
|
|
:ref:`dining-philosophers-sample` to visualize fast switching between threads.
