Pin Mapping
STM32F469I-DISCO Discovery kit has 9 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.
For more details please refer to 32F469IDISCOVERY board User Manual.
Default Zephyr Peripheral Mapping:
UART_3 TX/RX : PB10/PB11 (ST-Link Virtual Port Com)
UART_6 TX/RX : PG14/PG9 (Arduino Serial)
I2C1 SCL/SDA : PB8/PB9 (Arduino I2C)
SPI2 NSS/SCK/MISO/MOSI : PH6/PD3/PB14/PB15 (Arduino SPI)
SDIO D0/D1/D2/D3/CLK/Detect : PC8/PC9/PC10/PC11/PC12/PG2
USB DM : PA11
USB DP : PA12
USER_PB : PA0
LD1 : PG6
LD2 : PD4
LD3 : PD5
LD4 : PK3
System Clock
STM32F469I-DISCO 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 180MHz, driven by 8MHz high speed external clock.
Serial Port
The STM32F469 Discovery kit has up to 8 UARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.
Programming and Debugging
Applications for the stm32f469i_disco board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
STM32F469I-DISCO Discovery kit includes an ST-LINK/V2 embedded debug tool interface. This interface is supported by the openocd version included in Zephyr SDK.
Flashing an application to STM32F469I-DISCO
First, connect the STM32F469I-DISCO 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 stm32f469i_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 stm32f469i_disco samples/hello_world
west debug
