| The board has up to 8 UARTs, of which none are used. |
| |
| USB Port |
| ======== |
| |
| The ``stm32f429ii_aca`` board has a USB HS capable Mini-USB port. |
| It is connected to the on-chip OTG_HS peripheral. |
| |
| Programming and Debugging |
| ************************* |
| |
| The ``stm32f429ii_aca`` board supports the runners and associated west |
| commands listed below. |
| |
| .. zephyr:board-supported-runners:: |
| |
| 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 |
| ======== |
| |
| The IAR STM32F429II-ACA board has a MIPI20 connector to an JTAG/SWD interface |
| that can be used to program the MCU and then debug the application. This |
| interface can be used with an external debug probe such as a Segger J-Link. |
| |
| In preparation for flashing, connect the ``stm32f429ii_aca`` board's MIPI20 |
| DEBUG/TRACE interface to your external debug probe and then connect the debug |
| probe to your host computer. |
| |
| 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 |
| |
| LED1 should then begin to blink continuously with a 1-second delay. |
| |
| By default, the board uses the jlink runner for flashing operations. |
| Alternative runners for openocd or pyocd are also available and they are |
| accessible through the ``--runner`` (or ``-r``) option: |
| |
| .. code-block:: console |
| |
| $ west flash --runner openocd |
| $ west flash --runner pyocd |
