Pin Mapping
STM32F769I Discovery kit has 9 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.
For more details please refer to 32F769I-DISCO board User Manual.
Default Zephyr Peripheral Mapping:
UART_1 TX/RX : PA9/PA10 (ST-Link Virtual Port Com)
UART_6 TX/RX : PC6/PC7 (Arduino Serial)
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
I2C4 SCL/SDA : PD12/PB7 (Touchscreen FT6202, PI13 Interrupt Pin)
SPI2 SCK/MISO/MOSI : PA12/PB14/PB15 (Arduino SPI)
ETH : PA1, PA2, PA7, PC1, PC4, PC5, PG11, PG13, PG14
LD1 : PJ13
LD2 : PJ5
LD3 : PA12
LD4 : PD4
System Clock
The STM32F769I 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 216MHz, driven by a 25MHz high speed external clock.
Serial Port
The STM32F769I Discovery kit has up to 8 UARTs. The Zephyr console output is assigned to UART1 which connected to the onboard ST-LINK/V2 Virtual COM port interface. Default communication settings are 115200 8N1.
Programming and Debugging
STM32F769I Discovery kit includes an ST-LINK/V2 embedded debug tool interface.
Applications for the stm32f769i_disco board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
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
$ west flash --runner jlink
Flashing an application to STM32F769I
First, connect the STM32F769I 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 Hello World application.
# From the root of the zephyr repository
west build -b stm32f769i_disco samples/hello_world
west flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0
You should see the following message on the console:
Hello World! arm
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 stm32f769i_disco samples/hello_world
west debug
