Using GCC Compiler

By default the Board Layers are configured for the Arm Compiler 6 (AC6). Using STM32CubeMX it can be reconfigured for a different compiler. To configure it for the GCC compiler execute these steps:

  • In the <solution_name>.csolution.yml project file select compiler: GCC.
  • Launch the STM32CubeMX generator with this CMSIS-Toolbox command: csolution <solution_name>.csolution.yml run -g CubeMX -c <context>
  • In STM32CubeMX:
  • Open from the menu Project Manager - Project - Toolchain/IDE:
  • Select STM32CubeIDE and disable Generate Under Root.

  • Click GENERATE CODE to recreate the CubeMX generated files for the GCC compiler.

  • In the Board.clayer.yml file, update linker: node configuration to reference appropriate GCC linker script. The GCC linker script is typically generated in the STM32CubeMX/STM32CubeIDE folder. Customize the GCC linker script file to your project's requirements.

  • Rebuild the project using the CMSIS-Toolbox command cbuild <solution_name>.csolution.yml.
