| System Clock |
| ============ |
| |
| OLIMEX-STM32-H405 has two external oscillators. The frequency of |
| the slow clock is 32.768 kHz. The frequency of the main clock |
| is 8 MHz. The processor can setup HSE to drive the master clock, |
| which can be set as high as 168 MHz. |
| |
| Programming and Debugging |
| ************************* |
| The OLIMEX-STM32-H405 board does not include an embedded debug tool |
| interface. You will need to use ST tools or an external JTAG probe. |
| In the following examples a ST-Link V2 USB dongle is used. |
| |
| Flashing an application to the Olimex-STM32-H405 |
| ================================================ |
| |
| The sample application :ref:`hello_world` is being used in this tutorial. |
| |
| Connect the ST-Link USB dongle to your host computer and to the JTAG port of |
| the OLIMEX-STM32-H405 board. |
| |
| Now build and flash the application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: olimex_stm32_h405 |
| :goals: build flash |
| |
| Run a serial host program to connect with your board: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| After resetting the board, you should see the following message: |
| |
| .. code-block:: console |
| |
| *** Booting Zephyr OS build v2.7.99-3008-g2341052abe7c *** |
| Hello World! olimex_stm32_h405 |
| |
| |
| 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: olimex_stm32_h405 |
| :maybe-skip-config: |
| :goals: debug |
