System Clock
------------

By default, the system clock is driven by the external clock supplied by
the ST-LINK interface. Nucleo F722ZE system clock can be driven by internal
or external sources.

Serial Port
-----------

Zephyr console is assigned to UART3 (ST-Link Virtual COM Port) by default,
using 115200 8N1.

Programming and Debugging
*************************

The ``nucleo_f722ze`` can be flashed and debugged in the typical manner.
The Nucleo F722ZE board includes an ST-LINK V2-1 debugger, which can be used
with the OpenOCD version provided with the Zephyr SDK. Refer to
:ref:`build_an_application` and :ref:`application_run` for detailed
instructions.

Flashing
========

Build the :ref:`hello_world` application and flash it using the on-board
ST-LINK interface:

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: nucleo_f722ze
   :goals: build flash

Debugging
=========

.. zephyr-app-commands::
   :zephyr-app: samples/hello_world
   :board: nucleo_f722ze
   :maybe-skip-config:
   :goals: debug

J-Link OB Firmware
------------------

Like many other STM32 evaluation boards, the Nucleo F722ZE's on-board ST-LINK
debug interface may be flashed with `SEGGER J-Link OB firmware`_. This
firmware turns the ST-LINK into a J-Link probe. If the on-board debugger has
been re-flashed with J-Link OB firmware, simply append ``--runner jlink`` to
all flashing/debugging commands.
