STM32CubeMX incorrectly generates different .ld files depending on selected Toolchain / IDE

[thernstig]

STM32CubeMX generates a different .ld file depending on the selection under Project Manager -> Toolchain/IDE, when it should not.

Here are two examples, the first for CMake, and the second for STM32CubeIDE. I added them both to a .zip file.

STM32C071RBTX_FLASH.ld was generated when selecting STM32CubeIDE.

STM32C071RBTx_FLASH.ld was generated when selecting CMake.

Problem

The files should not have been regenerated. IT should have been the same name, with the same content. That two different files are generated shows for a bad implementation in STM32CubeMX for how it generates the .ld file.

[thernstig]

Adding a git diff for reference, see below. I also noticed that the STM32C071RBTx_FLASH.ld file generated by CMake does not work, see e.g. https://community.st.com/t5/stm32cubemx-mcus/f303-generated-ld-missing-ram-symbol-won-t-compile-includes-fix/m-p/722915.

@STTwo-32  How can this not have been fixed yet? It was 3 months ago it was reported, and it completely breaks building for CMake.

This is a known issue. For new Cmake build system they use a different way to generate .ld files. This is intentional unless new files are too broken or buggy. like missing  RAM  in "> RAM" and 

ORIGIN() + LENGTH()

[thernstig]

@Pavel A. I cannot see how that is true. If you diff the files properly you can see the are identical for the most part, but the one for CMake does not build due to bugs. Even simpler parts like the @brief description, and many other parts contain white space differences etc. The copyright dates are very different (the CMake one even says a date far before CMake support was added etc). I thus think your statement is incorrect. This is not intentional.

Do you have references showing this is intentional, and why some differences are there?

The reason I think it is not intential is because because the .ld file generated for STM32CubeIDE works great to use when building with CMake,

[Pavel A.]

I don't have references, just seen someone from ST commented earlier on CMake and VS Code support.  IIRC the difference is that the "legacy" way is just to copy a pre-made .ld file from library of templates. The new way is to generate the ld script from a database of STM32 models (where it gets sizes of flash and RAM blocks). This process still is a bit buggy. That's how I understood from that explanation.  The bug in Cmake .ld files has been reported here several times, should be in work.

Now to the point whether the [good] .ld file should not be clobbered when user switches to/from CMAKE build system... A good question. Generally, every time the Cube re-generates the project, it can cause damage and user should make backups and review changes in generated stuff.

[thernstig]

Then I think we all wish for ST to solve this soon, if it is known since far back. It is very strange to me the way this has been implemented, and a very large oversight to not even have it build. I am unsure how it got past code review/QA internally at ST.

CMake is paramount to enable developers to work in their own IDE of choice, which in 2024 is far from a big ask. It is the norm to let users use their own toolchain, be that a Jetbrains IDE, VS Code, VS, Eclipse (as-is), STM32CubeMX etc.

Note that even STM32CubeIDE supports CMake. So using CMake as the output Toolchain/IDE is always best.

Hello @thernstig 

This issue has been fixed in the latest CubeMX 6.13.0 , please download it from this LINK

Hi @Ghofrane GSOURI ,

There is a similar problem that using STM32cubemx and STM32cubeide to generate code for the same ioc may have two different ld files.

for example, for STM32H745, cubemx-cmake will generate stm32h745xx_flash_CM7.ld and stm32h745xx_sram1_CM7.ld

cubeide will generate STM32H745IIKX_FLASH.ld and STM32H745IIKX_RAM.ld

The file content is also different; for example, the cubemx-clion-generated ld file has the wrong RAM configurations.

cubeide generated ram ld file:

@hangx05 For Clion, please see here: "The following board configurations are not supported at the moment: ... dual-core lines of STM32H7".

Different .ld files generated for CMake and plain gcc toolchain are a feature, not bug.

Anyway if you use software provided/packaged with Clion, they are the address for support.
