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

.. zephyr:board-supported-runners::

The nucleo_f722ze can be flashed and debugged in the typical manner. The Nucleo F722ZE board includes an ST-LINK V2-1 debugger.

Refer to :ref:build_an_application and :ref:application_run for detailed instructions.

Flashing

The board is configured to be flashed using west STM32CubeProgrammer_ runner, so its :ref:installation <stm32cubeprog-flash-host-tools> is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

.. code-block:: console

$ west flash --runner openocd $ west flash --runner jlink

Build the :zephyr:code-sample: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
