Default Zephyr Peripheral Mapping:

The Nucleo H7S3L8 board features a ST Zio connector (extended Arduino Uno V3) and a ST morpho connector. Board is configured as follows:

UART_3 TX/RX : PD8/PD9 (ST-Link Virtual Port Com)
USER_PB : PC13
LD1 : PD10
LD2 : PD13
LD3 : PB7
I2C : PB8, PB9
SPI1 NSS/SCK/MISO/MOSI : PD14PA5/PA6/PB5 (Arduino SPI)

System Clock

Nucleo H7S3L8 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 600MHz, driven by an 24MHz high-speed external clock.

Serial Port

Nucleo H7S3L8 board has 4 UARTs and 3 USARTs plus one LowPower UART. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.

Backup SRAM

In order to test backup SRAM you may want to disconnect VBAT from VDD. You can do it by removing SB13 jumper on the back side of the board.

Programming and Debugging

Nucleo H7S3L8 board includes an ST-LINK/V3 embedded debug tool interface.

Note

Check if your ST-LINK V3 has newest FW version. It can be done with STM32CubeProgrammer

Flashing

The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

$ west flash --runner openocd

Flashing an application to Nucleo H7S3L8

First, connect the NUCLEO-H7S3L8 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 Hello World application.

Run a serial host program to connect with your NUCLEO-H7S3L8 board.

$ minicom -b 115200 -D /dev/ttyACM0

or use screen:

$ screen /dev/ttyACM0 115200

Build and flash the application:

# From the root of the zephyr repository
west build -b nucleo_h7s3l8 samples/hello_world
west flash

You should see the following message on the console:

$ Hello World! nucleo_h7s3l8

Blinky example can also be used:

# From the root of the zephyr repository
west build -b nucleo_h7s3l8 samples/basic/blinky
west flash

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b nucleo_h7s3l8 samples/hello_world
west debug
