Software Requirements

This toolchain leverages the following software tools:

• CMake (Build system)
• ARM GCC (Code generation toolchain)
• STM32CubeG4 (STM microcontroller header files)
• OpenOCD (Open source on-chip debugger)

For installation instructions see the developers guide

Quickstart

Clone this repository and navigate to the repository root:

git clone git@github.com:dronectl/stm32g431-toolchain.git
cd stm32g431-toolchain

Initialize the build system using cmake. Export compile commands to configure Intellisense:

mkdir build
cd build
# pass the basepath of the STM32CUBEG4 install directory
cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DSTM32CUBEG4_BASE=/Applications/stm/g4/STM32CubeG4
...

Compile the firmware

make -j
...

Plugin the evaluation board to your PC over mini USB and flash the microcontroller over UART:

make flash

OpenOCD automatically detects STLINK debugger interfaces over USB.
