Serial Port

By default, the STM32F429II-ACA evaluation board has no physical serial port available. The board has up to 8 UARTs, of which none are used.

USB Port

The STM32F429II-ACA evaluation board has a USB HS capable Mini-USB port. It is connected to the on-chip OTG_HS peripheral.

Programming and Debugging

Applications for the stm32f429ii_aca board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

In order to flash this board using west, an external debug probe such as a Segger J-Link has to be connected through the JTAG/SWD connector on the board. By default, the board is set to be flashed using the jlink runner. Alternatively, openocd, or pyocd can also be used as runners to flash the board using the --runner (or -r) option:

$ west flash --runner openocd
$ west flash --runner pyocd

First, connect the STM32F429II-ACA evaluation board to your host computer using your debug probe through the JTAG/SWD connector to prepare it for flashing. Then build and flash your application.

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b stm32f429ii_aca samples/basic/blinky
west flash

LED0 should then begin to blink continuously with a 1-second delay.
