+Serial Port
+===========
+
+By default, the STM32F429II-ACA evaluation board has no physical serial port available.
+The board has up to 8 UARTs, of which none are used.
+
+USB Port
+========
+
+The STM32F429II-ACA evaluation board has a USB HS capable Mini-USB port. It is connected to the on-chip
+OTG_HS peripheral.
+
+Programming and Debugging
+*************************
+
+Applications for the ``stm32f429ii_aca`` board configuration can be built
+and flashed in the usual way (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+Flashing
+========
+
+In order to flash this board using west, an external debug probe such as a Segger J-Link
+has to be connected through the JTAG/SWD connector on the board.
+By default, the board is set to be flashed using the jlink runner.
+Alternatively, openocd, or pyocd can also be used as runners to flash the board using
+the ``--runner`` (or ``-r``) option:
+
+.. code-block:: console
+
+   $ west flash --runner openocd
+   $ west flash --runner pyocd
+
+First, connect the STM32F429II-ACA evaluation board to your host computer using
+your debug probe through the JTAG/SWD connector to prepare it for flashing.
+Then build and flash your application.
+
+Here is an example for the :zephyr:code-sample:`blinky` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky
+   :board: stm32f429ii_aca
+   :goals: build flash
+
+LED0 should then begin to blink continuously with a 1-second delay.
