#######################
|
||||
|
||||
Overview
|
||||
********
|
||||
|
||||
The 32L4R9IDISCOVERY Discovery kit is a complete demonstration and development platform
|
||||
for STMicroelectronics Arm® Cortex®-M4 core-based STM32L4R9AI microcontroller.
|
||||
|
||||
Leveraging the innovative ultra-low-power oriented features, 640 Kbytes of embedded RAM,
|
||||
graphics performance (Chrom-ART Accelerator), and DSI controller offered by the STM32L4R9AI,
|
||||
the 32L4R9IDISCOVERY Discovery kit enables users to easily prototype applications with
|
||||
state-of-the-art energy efficiency, as well as stunning audio and graphics rendering with direct
|
||||
support for AMOLED DSI round LCD display.
|
||||
|
||||
For even more user-friendliness, the on-board ST-LINK/V2-1 debugger provides out-of-the-box
|
||||
programming and debugging capabilities.

|
||||
Other hardware features are not yet supported on Zephyr porting.
|
||||
|
||||
The default configuration can be found in the defconfig file:
|
||||
|
||||
``boards/arm/stm32l4r9i_disco/stm32l4r9i_disco_defconfig``
|
||||
|
||||
|
||||
Pin Mapping
|
||||
===========
|
||||
|
||||
For mode details, please refer to `STM32L4R9I-DISCOVERY website`_.
|
||||
|
||||
System Clock
|
||||
============
|
||||
|
||||
The STM32L4R9AI System Clock can be driven by an internal or external oscillator,
|
||||
as well as by the main PLL clock. By default, the System clock is driven by
|
||||
the PLL clock at 120MHz. PLL clock is driven by a 4MHz medium speed internal clock.
|
||||
|
||||
Serial Port
|
||||
===========
|
||||
|
||||
The STM32L4R9I Discovery board has up to 6 U(S)ARTs.
|
||||
The Zephyr console output is assigned to UART2, which is connected to the onboard
|
||||
ST-LINK Virtual COM port interface. Default communication settings are 115200 8N1.
|
||||
|
||||
|
||||
Programming and Debugging
|
||||
*************************
|
||||
|
||||
Flashing
|
||||
========
|
||||
|
||||
The STM32L4R9I Discovery board includes an ST-LINK/V2-1 debug tool.
|
||||
|
||||
Applications for the ``stm32l4r9i_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 an application to STM32L4R9I Discovery
|
||||
-----------------------------------------------
|
||||
|
||||
Connect the STM32L4R9I Discovery to your host computer using the ST-LINK
|
||||
USB port, then run a serial host program to connect with the board. For example:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ minicom -b 115200 -D /dev/ttyACM0
|
||||
|
||||
You can then build and flash applications in the usual way.
|
||||
Here is an example for the :ref:`hello_world` application.
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: stm32l4r9i_disco
|
||||
:goals: build flash
|
||||
|
||||
You should see the following message in the serial host program:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ Hello World! stm32l4r9i_disco
|
||||
|
||||
|
||||
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: stm32l4r9i_disco

||||
:goals: debug
