|
|
|
|
|
|
Pin Mapping
|
|
===========
|
|
|
|
STM32F469I-DISCO Discovery kit has 9 GPIO controllers. These controllers are responsible for pin muxing,
|
|
input/output, pull-up, etc.
|
|
|
|
For mode details please refer to `32F469IDISCOVERY board User Manual`_.
|
|

Programming and Debugging
|
|
*************************
|
|
|
|
Applications for the ``stm32f469i_disco`` board configuration can be built and
|
|
flashed in the usual way (see :ref:`build_an_application` and
|
|
:ref:`application_run` for more details).
|
|
|
|
Flashing
|
|
========
|
|
|
|
STM32F469I-DISCO Discovery kit includes an ST-LINK/V2 embedded debug tool interface.
|
|
This interface is supported by the openocd version included in Zephyr SDK.
|
|
|
|
Flashing an application to STM32F469I-DISCO
|
|
-------------------------------------------
|
|
|
|
First, connect the STM32F469I-DISCO Discovery kit to your host computer using
|
|
the USB port to prepare it for flashing. Then build and flash your application.
|
|
|
|
Here is an example for the :ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32f469i_disco
|
|
:goals: build flash
|
|
|
|
Run a serial host program to connect with your board:
|
|
|
|
.. code-block:: console
|
|
|
|
$ minicom -D /dev/ttyACM0
|
|
|
|
You should see the following message on the console:
|
|
|
|
.. code-block:: console
|
|
|
|
Hello World! arm
|
|
|
|
|
|
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: stm32f469i_disco
