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
The IAR STM32F429II-ACA board has a MIPI20 connector to an JTAG/SWD interface that can be used to program the MCU and then debug the application. This interface can be used with an external debug probe such as a Segger J-Link.
In preparation for flashing, connect the stm32f429ii_aca board’s MIPI20
DEBUG/TRACE interface to your external debug probe and then connect the debug
probe to your host computer.
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
LED1 should then begin to blink continuously with a 1-second delay.
By default, the board uses the jlink runner for flashing operations.
Alternative runners for openocd or pyocd are also available and they are
accessible through the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner pyocd
