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
.. zephyr:board-supported-runners::
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.
The sample application :zephyr:code-sample: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
You can debug an application in the usual way. Here is an example for the
:zephyr:code-sample:hello_world application.
