Hardware
--------

Platform :ref:`platform_openhw`: OpenHW Group is a not-for-profit, global organization that provides an infrastructure for hosting high quality open-source HW developments in line with industry best practices. The OpenHW CV32E40P RISC-V core is the first open-source core for high-volume chips verified with the state-of-the-art process required for high-integrity, commercial SoCs.

Configuration
-------------

Please use ``nexys_a7`` ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

.. code-block:: ini

  [env:nexys_a7]
  platform = openhw
  board = nexys_a7

You can override default Digilent Nexys A7 settings per build environment using
``board_***`` option, where ``***`` is a JSON object path from
board manifest `nexys_a7.json <https://github.com/platformio/platform-openhw/blob/master/boards/nexys_a7.json>`_. For example,
``board_build.mcu``, ``board_build.f_cpu``, etc.

.. code-block:: ini

  [env:nexys_a7]
  platform = openhw
  board = nexys_a7

  ; change microcontroller
  board_build.mcu = 

  ; change MCU frequency
  board_build.f_cpu = 320000000L

Debugging
---------

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

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

You can switch between debugging :ref:`debugging_tools` using
:ref:`projectconf_debug_tool` option in :ref:`projectconf`.

Digilent Nexys A7 has on-board debug probe and **IS READY** for debugging. You don't need to use/buy external debug probe.
