The NUCLEO-32 based F031K6 board STM32CubeMX based drivers

This is a repository that uses the IOC file generated from STM32CubeMX driver generation tool for the Nucleo-F031K6 board.

STM32CubeMX generation options

The following options are used while configuration of STM32CubeMX IOC project:

• generates for STM32CubeIDE (tested on version 1.13.1)
• generate low level drivers (stm32f0xx_hal_...) as links rather than files to make the driver more portable
• use the STM32CubeF0 firmware repository on GitHub as the low level drivers
• enforce the cubemx generated hal configuration file to guide the low level compilation

⚠️ LLVM Fails to find NULL

The auto generated file sysmem.c uses NULL in the source without including string.h header file. This has to be re-introduced each time for a successful build.

CMake definitions

The following CMake definitions are required for a successful build on ARM based llvm.

Type	Name	Value	Description
Environment	CORTEX_TYPE	CM0	Cortex M7 family name of the ARM controller to be used in cross compiler toolchain, always in UPPER_CASE
Environment	LLVM_CLANG_ROOT_FOLDER	toolchain path	absolute path to the folder location of the toolchain as a string
Environment	SEGGER_JLINK_ROOT_FOLDER	debugger tool path	absolute path to the folder location of the Segger JLink tools, used for tests on target hardware
CMake Cache Variable	DEMO	boolean	String value of true sets the build to include blinky application to work that lights up the LD1 and LD3 on the board alternatively at 50ms interval.
CMake Cache Variable	CMAKE_BUILD_TYPE	Debug/Release	String for debug optimised build.
CMake Cache Variable	CMAKE_TOOLCHAIN_FILE	path to cross compiler recepie	String value that provides path where the toolchain recepie is set, usually one of the cmake files in the toolchain repositiory.
CMake Cache Variable	GITHUB_BRANCH_TOOLCHAIN	string	String value of the GitHub branch or tag of the toolchain repoitory.
CMake Variable	STM32_TYPE	f0	String value of STM32 family.
CMake Variable	STM32_DEVICE	STH32F031x6	Case Sensitive string value of STM32 Device.
CMake Variable	JLINK_DEVICE	STM32F031K6	Case Sensitive string value of STM32 Device for Segger tools
CMake Cache Variable	STM32_HAL_CONFIGURATION	path to autogenerated HAL config file	Absolute path to the autogenerated stm32f0xx_hal_conf.h file to be used for correct configuration of the HAL layer, specially the clocks.

CMake presets

The following presets are available at the time of writing this

$ cmake --list-presets
Available configure presets:

  "llvm-target-test" - llvm-target-test
  "llvm-host-test"   - llvm-host-test

CMake Project structure for each preset

llvm-target-test

This is the preset to perform unity based unit tests directly on the target hardware using Segger RTT based JRun.

llvm-host-test

This is the preset to perform unity based unit tests on host machine (Windows/Linux/Darwin)
