ST 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.

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 | on-chip | gpio |
|
|
+-----------+------------+-------------------------------------+
|
|
| CLOCK | on-chip | reset and clock control |
|
|
+-----------+------------+-------------------------------------+
|
|
| WATCHDOG | on-chip | independent watchdog |
|
|
+-----------+------------+-------------------------------------+
|
|
|
|
Other hardware features are not currently supported by the port.
|
|
|
|
The default configuration can be found in the defconfig file:
|
|
``boards/arm/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:
|
|
----------------------------------
|
|
|
|
.. 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
|
|
*************************
|
|
|
|
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 STM32G0316-DISCO board includes an ST-LINK/V2-1 embedded debug tool
|
|
interface. This interface is not yet supported by the openocd version included in
|
|
the Zephyr SDK. Instead, support can be enabled on pyocd by adding "pack" support with
|
|
the following pyocd command:
|
|
|
|
.. code-block:: console
|
|
|
|
$ pyocd pack --update
|
|
$ pyocd pack --install stm32g031j6
|
|
|
|
Flashing an application to the STM32G0316-DISCO
|
|
-----------------------------------------------
|
|
|
|
Here is an example for the :ref:`blinky-sample` 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
|
|
:ref:`hello_world` application.
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: samples/hello_world
|
|
:board: stm32g0316_disco
|
|
:maybe-skip-config:
|
|
:goals: debug
