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

Supported Features
The Zephyr stm32g0316_disco board configuration supports the following hardware features:
Interface |
Controller |
Driver/Component |
|---|---|---|
NVIC |
on-chip |
nested vector interrupt controller |
UART |
on-chip |
serial port-polling; serial port-interrupt |
PINMUX |
on-chip |
pinmux |
GPIO |

Other hardware features are not currently supported by the port.
The default configuration can be found in the defconfig file: boards/st/stm32g0316_disco/stm32g0316_disco_defconfig
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 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
