| Programming and Debugging |
| ************************* |
| |
| Flashing |
| ======== |
| |
| STM32F3DISCOVERY Discovery kit includes a ST-LINK/V2 or ST-LINK/V2-B embedded |
| debug tool interface. |
| |
| Applications for the ``stm32f3_disco`` board configuration can be built and |
| flashed in the usual way (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Flashing an application to STM32F3DISCOVERY |
| ------------------------------------------- |
| |
| First, connect the STM32F3DISCOVERY Discovery kit to your host computer using |
| the USB port to prepare it for flashing. Then build and flash your application. |
| |
| Here is an example for the :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: stm32f3_disco |
| :goals: build flash |
| |
| Run a serial host program to connect with your board. For PCB version A or B a |
| TTL(3.3V) serial adapter is required. For PCB version C and newer a Virtual Com |
| Port (VCP) is available on the USB ST-LINK port. |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/<tty device> |
| |
| Replace <tty_device> with the port where the STM32F3DISCOVERY board can be |
| found. For example, under Linux, /dev/ttyUSB0. |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| Hello World! arm |
| |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: stm32f3_disco |
| :goals: debug |
