/** @defgroup boards_nucleo-g431rb STM32 Nucleo-G431RB @ingroup boards_common_nucleo64 @brief Support for the STM32 Nucleo-G431RB ## Overview The Nucleo-G431RB is a board from ST's Nucleo family supporting a ARM Cortex-M4 STM32G431RB microcontroller with 32KiB of RAM and 128KiB of Flash. ## Flashing the device ### Flashing the Board Using OpenOCD The ST Nucleo-G431RB board includes an on-board ST-LINK V3 programmer. The easiest way to program the board is to use OpenOCD. Once you have installed OpenOCD (look [here](https://github.com/RIOT-OS/RIOT/wiki/OpenOCD) for installation instructions), you can flash the board simply by typing ``` make BOARD=nucleo-g431rb flash ``` and debug via GDB by simply typing ``` make BOARD=nucleo-g431rb debug ``` ### Flashing the Board Using ST-LINK Removable Media On-board ST-LINK programmer provides via composite USB device removable media. Copying the HEX file causes reprogramming of the board. This task could be performed manually; however, the cpy2remed (copy to removable media) PROGRAMMER script does this automatically. To program board in this manner, use the command: ``` make BOARD=nucleo-g431re PROGRAMMER=cpy2remed flash ``` @note This PROGRAMMER was tested using ST-LINK firmware 2.37.26. Firmware updates could be found on [this STM webpage](https://www.st.com/en/development-tools/stsw-link007.html). ## Supported Toolchains For using the ST Nucleo-G431RB board we recommend the usage of the [GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded) toolchain. */
