Tools & Debug Probes
~~~~~~~~~~~~~~~~~~~~

Supported debugging tools are listed in "Debug" column. For more detailed
information, please scroll table by horizontal.
You can switch between debugging :ref:`debugging_tools` using
:ref:`projectconf_debug_tool` option in :ref:`projectconf`.

.. warning::
    You will need to install debug tool drivers depending on your system.
    Please click on compatible debug tool below for the further instructions.


External Debug Tools
^^^^^^^^^^^^^^^^^^^^

Boards listed below are compatible with :ref:`piodebug` but **DEPEND ON**
external debug probe. They **ARE NOT READY** for debugging.
Please click on board name for the further details.
