Stm32 tools evaluation

Trying out some setup combination with "Ac6 System Workbench" (Eclipse plugin) and Stm32cubemx

Conclusion

Conclusion-01

• create projects using System Workbench (eclipse plugin)
  • Name = Conclusion-01
  • ⦿ Cube Hal
  • ☑ Add low level drivers in this project
  • ⦿ As sources in the application project
  • about the CMSIS, HAL_Driver and Utility directory (and maybe even the startup directory), I think I'll move it later to a central place (e.g. Foundation)
• create CubeMX project with the same name
  • locate it into a subfolder (cubemx) of the System Workbench project
  • Project
    • Name = Conclusion-01
    • Project Location = C:\Papa\git\Joe\Stm32-Tools-Evaluation\Conclusion-01\cubemx
    • Toolchain = SW4STM32
    • and ignore the generated .project / .cproject
    • save → C:\Papa\git\Joe\Stm32-Tools-Evaluation\Conclusion-01\cubemx\Conclusion-01\Conclusion-01.ioc → /D/git/Joe/Stm32-Tools-Evaluation/Conclusion-01/cubemx/Conclusion-01/Conclusion-01.ioc
    • generate code
• add cubemx include path and source path to eclipse project
• main redirect, missing include in gpio.c,
• TODO ...

• the "SW" in the project names below stands for "System Workbench"

• all projects are located locally in /D/git/Joe/Stm32-Tools-Evaluation

• example project created for Stm32F401C-Disco board with STM32F401VCTx (256k Flash, 64k Ram)

• File → new → C++ Project → Ac6 Stm32 Mcu Project

  • Name = Stm32F4-SW-nofw

    • Location = /D/git/Joe/Stm32-Tools-Evaluation/Stm32F4-SW-nofw
    • Chips = Stm32F4, Board = Stm32F401C-Disco
    • Firmware Configuration = ⦿ No Firmware → no main.c

  • Stm32F4-SW-cubehal

    • Firmware Configuration = ⦿ Cube Hal
      • Stm32Cube_FW_F4_V1.9.0 ☐ Extract all firmware in separate folder ☐ Add low level drivers in this project → project looks same as "nofw"

  • Stm32F4-SW-cubehal-sepfolder

    • Firmware Configuration = ⦿ Cube Hal ☑ Extract all firmware in separate folder ☐ Add low level drivers in this project → project looks same as "nofw" and "Stm32F4-SW-cubehal" → cube hal sources were put to to workspace/STM32Cube_FW_F4_V1.9.0 (23608 files, 7288 directories, 1,1 GiB!)
    • including things like "audio_sample.wav", "SetupSTM32CubeUpdater-4.2.0.exe" ... → I'd moved them to my git repo

  • Stm32F4-SW-cubehal-source

    • Firmware Configuration = ⦿ Cube Hal ☐ Extract all firmware in separate folder ☑ Add low level drivers in this project ⦿ As sources in the application project ⦾ As static external libraries → adds 3 directories (CMSIS, HAL_Driver, Utilities) to the project (171 files, 33 directories, 64 MiB) → much more stuff in .cproject → !!! for unknown reason, this generates a project with a linker script differen to e.g. Stm32F4-SW-cubehal
    • Stm32F4-SW-cubehal: Linker script for STM32F401VCTx
    • but here: Linker script for STM32F401CC
    • http://www.openstm32.org/tiki-view_forum_thread.php?comments_parentId=1438 → different things in startup directory
    • Stm32F4-SW-cubehal: startup_stm32.s (author="Ac6")
    • Stm32F4-SW-cubehal-source: versus startup_stm32f401xc.s (author="MCD Application Team") → 32 include paths added (all for 6 times gcc, gxx, asm / debug & release)

  • Stm32F4-SW-cubehal-lib

    • Firmware Configuration = ⦿ Cube Hal ☐ Extract all firmware in separate folder ☑ Add low level drivers in this project ⦾ As sources in the application project ⦿ As static external libraries → adds a project "stm32f401c-disco_hal_lib" to the workspace (default workspace location) with the 3 directories (CMSIS, HAL_Driver, Utilities) (279 files, 37 directories, 65 MiB!) → I'd moved them to my git repo → when creating such project a second time, the .cproject seems to be incomplete (e.g. all of the includepaths, ...)

Setup start with CubeMX

• projects created with CubeMX Version 4.11.0, running on Windows 7, 64 Bit

• File → New Project → Board Selector → Stm32F401C-Disco

• Project Settings

  • see also 05_STM32L4_Putting_All_Together.pdf, page 49ff
  • Project
    • Name = Stm32F4-MX-copyAll
    • Project Location = C:\Papa\git\Joe\Stm32-Tools-Evaluation
    • Toolchain = SW4STM32
  • Code Generator
    • Cube Firmware Library Package
      • ⦾ Copy all used libraries into the project folder → TODO: check the effect
      • ⦿ Copy only the necessary library files → TODO: check the effect
      • ⦾ Add necessary library files as reference in the toolchain project configuration file → TODO: check the effect
    • Generated Files
      • ☑ Generate peripheral initialization as a pair of .c/.h files per IP → TODO: check the effect
      • ☐ Backup previously generated files when re-generating
      • ☑ Keep user code when when re-generating
      • ☑ Delete previously generated files when not re-generated
    • Hal Settings
      • ☐ Set all free pins as analog → TODO: check the effect
      • ☐ Enable full assert → TODO: check the effect

• Save Project, results in a Stm32F4-MX-copyAll/Stm32F4-MX-copyAll.ioc

• removed that "Configuration" postfix from .project (1x) and .cproject (5x) → STM32F401VCTx_FLASH.ld looks close like the LinkerScript.ld in Stm32F4-SW-cubehal-source and Stm32F4-SW-cubehal-lib →

Directory Structure

• ProjectRoot
  • .project, .cproject, .settings → generated by Eclipse Wizard
  • cubemx → generated code from cubemx
  • inc, src → application source
  • Debug, Release → output directories
