| |
| Programming and Debugging |
| ************************* |
| |
| Flashing |
| ======== |
| |
| Nucleo F411RE board includes an ST-LINK/V2-1 embedded debug tool interface. |
| This interface is supported by the openocd version included in Zephyr SDK. |
| |
| Flashing an application to Nucleo F411RE |
| ---------------------------------------- |
| |
| The sample application :ref:`hello_world` is being used in this tutorial: |
| |
| .. code-block:: console |
| |
| $<zephyr_root_path>/samples/hello_world |
| |
| 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=nucleo_f411re |
| |
| Connect the Nucleo F411RE to your host computer using the USB port. |
| Then, enter the following command: |
| |
| .. code-block:: console |
| |
| $ make BOARD=nucleo_f411re flash |
| |
| Run a serial host program to connect with your Nucleo board. |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| You should see the following message: |
| |
| .. code-block:: console |
| |
| $ Hello World! arm |
| |
| |
| Debugging |
| ========= |
| |
| Access gdb with the following make command: |
| |
| .. code-block:: console |
| |
| $ make BOARD=nucleo_f411re debug |
