Overview
|
||||||
|
********
|
||||||
|
|
||||||
|
The STM32H745I-DISCO Discovery kit is a complete demonstration and development

|
eMMC, USART, SAI audio DAC stereo with audio jack input and output, MEMS digital microphone, SDRAM,
|
||||||
|
Quad-SPI flash memory, and RGB interface LCD with capacitive multi-touch panel). ARDUINO |reg| Uno V3
|
||||||
|
connectors provide easy connection to extension shields or daughterboards for specific applications.

System Clock
|
||||||
|
------------
|
||||||
|
|
||||||
|
STM32H745I-DISCO System Clock could be driven by an internal or external
|
||||||
|
oscillator, as well as the main PLL clock. By default, the System clock is
|
||||||
|
driven by the PLL clock at 480MHz, driven by an 25MHz high-speed external clock.
|
||||||
|
|
||||||
|
Serial Port
|
||||||
|
-----------
|
||||||
|
|
||||||
|
STM32H745I-DISCO board has 4 UARTs and 4 USARTs. The Zephyr console output is
|
||||||
|
assigned to UART3. Default settings are 115200 8N1.
|
||||||
|
|
||||||
|
Resources sharing
|
||||||
|
-----------------
|
||||||
|
|
||||||
|
The dual core nature of STM32H745 SoC requires sharing HW resources between the
|
||||||
|
two cores. This is done in 3 ways:
|
||||||
|
|
||||||
|
- **Compilation**: Clock configuration is only accessible to M7 core. M4 core only
|
||||||
|
has access to bus clock activation and deactivation.
|
||||||
|
- **Static pre-compilation assignment**: Peripherals such as a UART are assigned in
|
||||||
|
devicetree before compilation. The user must ensure peripherals are not assigned
|
||||||
|
to both cores at the same time.
|
||||||
|
- **Run time protection**: Interrupt-controller and GPIO configurations could be
|
||||||
|
accessed by both cores at run time. Accesses are protected by a hardware semaphore
|
||||||
|
to avoid potential concurrent access issues.
|
||||||
|
|
||||||
|
Programming and Debugging
|
||||||
|
*************************
|
||||||
|
|
||||||
|
Applications for the ``stm32h745i_disco`` board should be built per core target,
|
||||||
|
using either ``stm32h745i_disco/stm32h745xx/m7`` or ``stm32h745i_disco/stm32h745xx/m4`` as the target
|
||||||
|
(see :ref:`build_an_application` and :ref:`application_run` for more details).
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
Check if the on-board ST-LINK V3 has the latest firmware version. It can be done with either `STM32CubeIDE`_ or `STM32CubeProgrammer`_
|
||||||
|
|
||||||
|
Flashing
|
||||||
|
========
|
||||||
|
|
||||||
|
STM32H745I-DISCO board includes an ST-LINK/V3 embedded debug tool interface.
|
||||||
|
|
||||||
|
Flashing operation will depend on the target and the SoC
|
||||||
|
option bytes configuration.
|
||||||
|
|
||||||
|
By default:
|
||||||
|
|
||||||
|
- CPU0 (Cortex-M7) boot address is set to 0x80000000 (OB: BOOT_CM7_ADD0)
|
||||||
|
- CPU1 (Cortex-M4) boot address is set to 0x81000000 (OB: BOOT_CM4_ADD0)
|
||||||
|
|
||||||
|
Also, the out of the box default board configuration enables CM7 and CM4 boot when
|
||||||
|
board is powered (Option bytes BCM7 and BCM4 are checked).
|
||||||
|
In that configuration, Kconfig boot option ``STM32H7_BOOT_CM4_CM7`` should be selected.
|
||||||
|
Zephyr flash configuration has been set to meet these default settings.
|
||||||
|
|
||||||
|
Alternatively, west `STM32CubeProgrammer`_ runner can be used, after installing
|
||||||
|
it, to flash applications for both cores. The target core is detected automatically.
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ west flash --runner stm32cubeprogrammer
|
||||||
|
|
||||||
|
Flashing an application to STM32H745XI M7 Core
|
||||||
|
----------------------------------------------
|
||||||
|
First, connect the STM32H745I-DISCO 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.
|
||||||
|
|
||||||
|
Run a serial host program to connect with your STM32H745I-DISCO board.
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ minicom -b 115200 -D /dev/ttyACM0
|
||||||
|
|
||||||
|
or use screen:
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ screen /dev/ttyACM0 115200
|
||||||
|
|
||||||
|
Build and flash the application:
|
||||||
|
|
||||||
|
.. zephyr-app-commands::
|
||||||
|
:zephyr-app: samples/hello_world
|
||||||
|
:board: stm32h745i_disco/stm32h745xx/m7
|
||||||
|
:goals: build flash
|
||||||
|
|
||||||
|
You should see the following message on the console:
|
||||||
|
|
||||||
|
.. code-block:: console
|
||||||
|
|
||||||
|
$ Hello World! stm32h745i_disco
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
Sometimes, flashing does not work properly. It is necessary to erase the flash
|
||||||
|
(with STM32CubeProgrammer for example) to make it work again.
|
||||||
|
|
||||||
|
Similarly, you can build and flash samples on the M4 target. For this, please
|
||||||
|
take care of the resource sharing (UART port used for console for instance).
|
||||||
|
|
||||||
|
Here is an example for the :zephyr:code-sample:`blinky` application on M4 core.
|
||||||
|
|
||||||
|
.. zephyr-app-commands::
|
||||||
|
:zephyr-app: samples/basic/blinky
|
||||||
|
:board: stm32h745i_disco/stm32h745xx/m7
|
||||||
|
:goals: build flash
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
Flashing both M4 and M7 and pushing RESTART button on the board leads
|
||||||
|
to LD1 and LD2 flashing simultaneously.
|
||||||
|
|
||||||
|
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: stm32h745i_disco/stm32h745xx/m7
|
||||||
|
:maybe-skip-config:
|
||||||
|

Debugging with west is currently not available on Cortex M4 side.
|
||||||
|
In order to debug a Zephyr application on Cortex M4 side, you can use
|
||||||
|
`STM32CubeIDE`_.
