| The default configuration can be found in the defconfig file: |
| :zephyr_file:`boards/st/nucleo_g0b1re/nucleo_g0b1re_defconfig` |
| |
| Connections and IOs |
| =================== |
| |
| Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as |
| input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the |
| GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current |
| capable except for analog inputs. |

| |
| Programming and Debugging |
| ************************* |
| |
| Nucleo G0B1RE board includes an ST-LINK/V2-1 embedded debug tool interface. |
| |
| Applications for the ``nucleo_g0b1re`` board configuration can be built and |
| flashed in 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, JLink, or pyOCD 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 |
| $ west flash --runner pyocd |
| |
| For STM32G0 support pyocd needs additional target information, |
| which can be installed by adding "pack" support with the following pyocd command: |
| |
| .. code-block:: console |
| |
| $ pyocd pack --update |
| $ pyocd pack --install stm32g0 |
| |
| Flashing an application to Nucleo G0B1RE |
| ---------------------------------------- |
| |
| Here is an example for the :zephyr:code-sample:`blinky` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: nucleo_g0b1re |
| :goals: build 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 |
| :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nucleo_g0b1re |
| :maybe-skip-config: |
| :goals: debug |
