| The default configuration can be found in the defconfig and dts files: |
| |
| - Common: |
| |
| - :zephyr_file:`boards/st/stm32l562e_dk/stm32l562e_dk_common.dtsi` |
| |
| - Secure target: |

| |
| Zephyr board options |
| ==================== |
| |
| The STM32L562e is an SoC with Cortex-M33 architecture. Zephyr provides support |
| for building for both Secure and Non-Secure firmware. |
| |
| The BOARD options are summarized below: |
| |
| +------------------------------+-------------------------------------------+ |
| | BOARD | Description | |
| +==============================+===========================================+ |
| | stm32l562e_dk | For building Trust Zone Disabled firmware | |
| +------------------------------+-------------------------------------------+ |
| | stm32l562e_dk/stm32l562xx/ns | For building Non-Secure firmware | |
| +------------------------------+-------------------------------------------+ |
| |
| Here are the instructions to build Zephyr with a non-secure configuration, |
| using :zephyr:code-sample:`tfm_ipc` sample: |
| |
| .. code-block:: bash |
| |
| $ west build -b stm32l562e_dk/stm32l562xx/ns samples/tfm_integration/tfm_ipc/ |
| |
| Once done, before flashing, you need to first run a generated script that |
| will set platform option bytes config and erase platform (among others, |
| option bit TZEN will be set). |
| |
| .. code-block:: bash |
| |
| $ ./build/tfm/api_ns/regression.sh |
| $ west flash |
| |
| Please note that, after having run a TFM sample on the board, you will need to |
| run ``./build/tfm/api_ns/regression.sh`` once more to clean up the board from secure |
| options and get back the platform back to a "normal" state and be able to run |
| usual, non-TFM, binaries. |
| Also note that, even then, TZEN will remain set, and you will need to use |
| STM32CubeProgrammer_ to disable it fully, if required. |
| |
| Connections and IOs |
| =================== |
| |
| STM32L562E-DK Discovery Board has 8 GPIO controllers. These controllers are responsible for pin muxing, |
| input/output, pull-up, etc. |
| |
| For more details please refer to `STM32L562E-DK Discovery board User Manual`_. |
| |

| |
| STM32L562E-DK System Clock could be driven by internal or external oscillator, |
| as well as main PLL clock. By default System clock is driven by PLL clock at |
| 110MHz, driven by 4MHz medium speed internal oscillator. |
| |
| Serial Port |
| ----------- |
| |
| STM32L562E-DK Discovery board has 6 U(S)ARTs. The Zephyr console output is |
| assigned to USART1. Default settings are 115200 8N1. |

| |
| Programming and Debugging |
| ************************* |
| |
| STM32L562E-DK Discovery board includes an ST-LINK/V3E embedded debug tool interface. |
| |
| Applications for the ``stm32l562e_dk`` 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 board is configured to be flashed using west `STM32CubeProgrammer`_ runner, |
| so its :ref:`installation <stm32cubeprog-flash-host-tools>` is required. |
| |
| Alternatively, OpenOCD can also be used to flash the board using |
| the ``--runner`` (or ``-r``) option: |
| |
| .. code-block:: console |
| |
| $ west flash --runner openocd |
| |
| Support can also be enabled for pyOCD by adding "pack" support with the |
| following pyOCD commands: |
| |
| .. code-block:: console |
| |
| $ pyocd pack --update |
| $ pyocd pack --install stm32l562qe |
| |
| Flashing an application to STM32L562E-DK Discovery |
| -------------------------------------------------- |
| |
| Connect the STM32L562E-DK Discovery to your host computer using the USB port. |
| Then build and flash an application. Here is an example for the |
| :zephyr:code-sample:`hello_world` application. |
| |
| Run a serial host program to connect with your Nucleo board: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| Then build and flash the application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: stm32l562e_dk |
| :goals: build flash |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| Hello World! stm32l562e_dk |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: stm32l562e_dk |
| :maybe-skip-config: |
