System Clock

STM32N6570_DK System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 400MHz, driven by 64MHz high speed internal oscillator.

Serial Port

STM32N6570_DK board has 10 U(S)ARTs. The Zephyr console output is assigned to USART1. Default settings are 115200 8N1.

Programming and Debugging

STM32N6570_DK board includes an ST-LINK/V3 embedded debug tool interface. This probe allows to flash and debug the board using various tools.

Flashing or loading

The board is configured to be programmed using west STM32CubeProgrammer runner, so its :ref:`installation <stm32cubeprog-flash-host-tools>` is needed. Version 2.18.0 or later of STM32CubeProgrammer is required.

Note

Firmware is run in secure mode of execution, which requires a signature. After build, the build system will automatically generate a signed version of the binary using STM32CubeProgrammer utility STM32_SigningTool_CLI. This utility is installed along with STM32CubeProgrammer, but make sure it is available in your PATH variable.

To program the board, there are two options:

  • Program the firmware in external flash. At boot, it will then be loaded on RAM and executed from there.
  • Optionally, it can also be taken advantage from the serial boot interface provided by the boot ROM. In that case, firmware is directly loaded in RAM and executed from there. It is not retained.

Programming an application to STM32N6570_DK

Here is an example to build and run :zephyr:code-sample:`hello_world` application.

First, connect the STM32N6570_DK to your host computer using the ST-Link USB port.

.. tabs::

   .. group-tab:: ST-Link

      Build and flash an application using ``stm32n6570_dk`` target.

      .. zephyr-app-commands::
         :zephyr-app: samples/hello_world
         :board: stm32n6570_dk
         :goals: build flash

      .. note::
         For flashing, before powering the board, set the boot pins in the following configuration:

         * BOOT0: 0
         * BOOT1: 1

         After flashing, to run the application, set the boot pins in the following configuration:

         * BOOT1: 0

         Power off and on the board again.

   .. group-tab:: Serial Boot Loader (USB)

      Additionally, connect the STM32N6570_DK to your host computer using the USB port.
      In this configuration, ST-Link is used to power the board and for serial communication
      over the Virtual COM Port.

      .. note::
         Before powering the board, set the boot pins in the following configuration:

         * BOOT0: 1
         * BOOT1: 0

      Build and load an application using ``stm32n6570_dk/stm32n657xx/sb`` target (you
      can also use the shortened form: ``stm32n6570_dk//sb``)

      .. zephyr-app-commands::
         :zephyr-app: samples/hello_world
         :board: stm32n6570_dk//sb
         :goals: build flash

Run a serial host program to connect with your Disco board:

$ minicom -D /dev/ttyACM0

You should see the following message on the console:

Hello World! stm32n6570_dk/stm32n657xx

Debugging

For now debugging is only available through STM32CubeIDE:

  • Go to File > Import and select C/C++ > STM32 Cortex-M Executable.
  • In Executable field, browse to your <ZEPHYR_PATH>/build/zephyr/zephyr.elf.
  • In MCU field, select STM32N657X0HxQ.
  • Click on Finish.
  • Finally, click on Debug to start the debugging session.

Note

For debugging, before powering on the board, set the boot pins in the following configuration:

  • BOOT0: 0
  • BOOT1: 1

Running tests with twister

Due to the BOOT switches manipulation required when flashing the board using stm32n6570_dk board target, it is only possible to run twister tests campaign on stm32n6570_dk/stm32n657xx/sb board target which doesn't require BOOT pins changes to load and execute binaries. To do so, it is advised to use Twister's hardware map feature with the following settings:

- platform: stm32n6570_dk/stm32n657xx/sb
  product: BOOT-SERIAL
  pre_script: <path_to_zephyr>/boards/st/common/scripts/board_power_reset.sh
  runner: stm32cubeprogrammer
