This is another STM32F3Discovery example Project.

It uses the STM32Cube-F3-meson repo which is optimised for the meson build system.

STM32Cube-f3-meson

For myself: I hate using eclipse. And also I hate writing Makefiles. So I had to find another build system to program my precious microcontrollers.

I read about the mesonbuild system and though that could be an interesting solution.

Meson is an open source build system meant to be both extremely fast, and, even more importantly, as user friendly as possible.

Meson uses the so called ninja back-end.

Ninja is a small build system with a focus on speed. It differs from other build systems in two major respects: it is designed to have its input files generated by a higher-level build system, and it is designed to run builds as fast as possible.

Both are optimized for speed.

And also I can configure meson to use llvm. Which is also just a personal preference of mine. If I got the time I will also make this script workable with an arm-none-eabi-gcc compiler.

create the build folder, create the meson project and start compilation

  mkdir llvmbuild
  meson --cross-file=cross_file.build
  cd llvmbuild
  ninja

now connect your target and run openocd in a new terminal

  openocd -f interface/stlink-v2.cfg -f target/stm32f3x.cfg

goto your first terminal and start the gdb session

  arm-none-eabi-gdb -q llvmbuild/main.elf

Type the following command into the gdb console

  continue

enjoy!

take a look here : Toochain.md

go to your destination folder and clone the repo in

  git clone https://github.com/hwengineer/STM32F3Discovery-meson-example.git
  cd STM32F3Discovery-meson-example
  git submodule update --init --recursive

And no use the commands above for compilation and testing.

• blink frequency is way below what is to be expected. Maybe a configuration problem
