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.
