| ################# |
| |
| Overview |
| ******** |
| |
| Zephyr applications use the olimex_stm32_e407 board configuration |
| to run on the OLIMEX-STM32-E407 open source hardware. It is based on |
| the STMicroelectronics STM32F407ZG ARM Cortex-M4 CPU. |

| System Clock |
| ============ |
| |
| OLIMEX-STM32-E407 has two external oscillators. The frequency of |
| the slow clock is 32.768 kHz. The frequency of the main clock |
| is 12 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-E407 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-E407 |
| ================================================ |
| |
| The sample application :ref:`hello_world` is being used in this tutorial. To |
| build the Zephyr kernel and application, enter: |
| |
| .. code-block:: console |
| |
| $ cd <zephyr_root_path> |
| $ source zephyr-env.sh |
| $ cd $ZEPHYR_BASE/samples/hello_world/ |
| $ make BOARD=olimex_stm32_e407 |
| |
| Connect the ST-Link USB dongle to your host computer and to the JTAG port of |
| the OLIMEX-STM32-E407 board. |
| Then, enter the following command: |
| |
| .. code-block:: console |
| |
| $ make BOARD=olimex_stm32_e407 flash |
| |
| Run a serial host program to connect with your board: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| After reseting the board you should see the following message: |
| |
| .. code-block:: console |
| |
| ***** BOOTING ZEPHYR OS v1.8.99 - BUILD: May 29 2017 22:31:53 ***** |
| Hello World! arm |
| |
| Debugging |
| ========= |
| |
| Access gdb with the following make command: |
| |
| .. code-block:: console |
| |
| $ make BOARD=olimex_stm32_e407 debug |
