Tip

When using this board with RIOT, set the BOARD variable to stm32f469i-disco in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= stm32f469i-disco

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Reference Manual	Dev-Kit Reference Manual (pdf)

Connectors and Pinout

• 1 USB Mini-B used by the On-board ST-LINK debugger (Ref.CN1)
• 1 USB Micro-AB Full speed (Ref. CN13)
• Arduino(R) Uno expansion connectors (Refs. CN5/6/7/8)
• microSD(tm) card receptacle.
• Audio 3.5 mm stereo jack

Through 2 connector we have available:

CN11

• I2C1
• Reset

Also provides power pins, 3V3 and GND

CN12

This extension connector gives access to:

• CAN2
• USART6 (Tx, Rx)
• I2S2
• SPI1
• 7 timers channels
• Speaker output (1W)

Also provides some system signals and power.

Important! note than some pins are shared between peripherals.

Buttons, LEDS and other devices

• 1 Button for reset
• 1 User button
• 4 LEDs
• 3 Digital microphones
• 1 LCD Color 4 inches

Working with this Dev-Kit

To start the gcc-arm-embedded toolchain have to be installed, we can follow the usual process here.

Flashing the device

Flashing the Board using OpenOCD

The start install OpenOCD, also we can follow the usual process here

Once everything is installed and ready to work just connect the board through the USB Mini-B connector try to compile and flash some code, type:

make flash BOARD=stm32f469i-disco

Flashing the Board Using ST-LINK Removable Media

On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command:

make BOARD=stm32f469i-disco PROGRAMMER=cpy2remed flash

Note: This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware update s could be found on [this STM webpage](https://www.st.com/en/development-tools/sts w-link007.html).
