STM32G0316 Discovery

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

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:

  • UART_1 TX/RX : PA9/PB7 (pins 5/1)

  • USER_PB : PA0 (pin 4)

  • LD2 : PA12 (pin 6)

Programming and Debugging

The stm32g0316_disco board supports the runners and associated west commands listed below.

flash debug

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 Building an Application and Run an Application for more details).

Flashing

The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.

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

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

Flashing an application to the STM32G0316-DISCO

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b stm32g0316_disco samples/basic/blinky
west 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 Hello World application.

# From the root of the zephyr repository
west build -b stm32g0316_disco samples/hello_world
west debug
