.. zephyr:board:: stm32g0316_disco

Overview

The STM32G0316-DISCO Discovery kit helps to discover features of STM32G0 in SO8 package. This discovery kit offers an SO8 to DIL8 module designed with the STM32G031J6 microcontroller and allows the user to develop applications. It includes an on-board ST-LINK/V2-1 to debug and program the embedded STM32 microcontroller.

Hardware

STM32G031J6 Arm® Cortex®-M0+ core-based microcontroller, featuring 32 Kbytes of Flash memory and 8 Kbytes of SRAM, in an SO8 package
1 user LED
1 reset/user push-button
Individual and breakable STM32 SO8 to DIL8 module
ST-LINK Micro-B USB connector
DIL8 socket to ease programming of the STM32 MCU
On-board ST-LINK/V2-1 debugger/programmer

Supported Features

.. zephyr:board-supported-hw::

Connections and IOs

Due to the small number of I/O pins on the SO8 package, multiple die I/Os are bonded to the same package pins to maximize the number of peripherals which can be used. Care must be taken not to set two I/Os which are connected together to conflicting states (e.g. both as outputs, one low, the other high).

Default Zephyr Peripheral Mapping:

.. rst-class:: rst-columns

UART_1 TX/RX : PA9/PB7 (pins 5/1)
USER_PB : PA0 (pin 4)
LD2 : PA12 (pin 6)

Programming and Debugging

.. zephyr:board-supported-runners::

The STM32G0316-DISCO board includes an ST-LINK/V2-1 embedded debug tool interface.

Applications for the stm32g0316_disco board configuration can be built the usual way (see :ref:build_an_application and :ref:application_run for more details).

Flashing

The board is configured to be flashed using west STM32CubeProgrammer_ runner, so its :ref:installation <stm32cubeprog-flash-host-tools> is required.

Alternatively, OpenOCD or JLink can also be used to flash the board using the --runner (or -r) option:

.. code-block:: console

$ west flash --runner openocd $ west flash --runner jlink

Flashing an application to the STM32G0316-DISCO

Here is an example for the :zephyr:code-sample:blinky application.

.. zephyr-app-commands:: :zephyr-app: samples/basic/blinky :board: stm32g0316_disco :goals: build flash

You should see the LED blinking every second.

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: stm32g0316_disco :maybe-skip-config: :goals: debug
