STM32F030 DEMO BOARD

This board has the bare minimum components required to power on the STM32F030F4P6 MCU. Most of the GPIOs on the STM32 SoC have been exposed in the external headers with silk screen labels that match the SoC’s pin names.

For practical use, you’ll need to add additional components and circuits using a breadboard, for example.

Programming and Debugging

Applications for the stm32f030_demo 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 can be flashed by using ST-LINKV2 in-circuit debugger and programmer. This interface is supported by the openocd version included in the Zephyr SDK.

Flashing an application to STM32F030 DEMO BOARD

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b stm32f030_demo samples/basic/blinky
west flash

You will see the LED blinking every second.

Debugging

You can debug an application in the usual way. Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b stm32f030_demo samples/basic/blinky
west debug
