FLASH.ld syntax error when upgrading to CubeMX v6.12.1

[OmidES]

Hello,

Since the latest release of CubeMX (6.12.1), I have been encountering syntax errors related to the "FLASH.ld" file. This issue only arises when I generate code while setting the Toolchain/IDE to CMake. I am using STM32H753IIKx. It seems that CubeMX does not specify which RAM to use when setting the Toolchain/IDE to CMake.

I have also included the FLASH.ld file that was generated for your reference.

 

Thanks for your help.

It's been at least TWO MONTHS since this major, show-stopping bug was reported. WTF ST? Get your act together. This is appalling.

Hello @OmidES 

Issue has been solved on the STM32CubeMX V6.13.0.

Best Regards.

Hi,

I still get the same error even with STM32CubeMX V6.13.0.

 

Thanks

Have you created a new project from the beginning? Please try this.

Still not fixed for me on Version 6.13.0

I get the following error when trying to build blank project for STM32F407ZGT

 

c:/program files (x86)/gnu arm embedded toolchain/10 2021.10/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe:stm32f407zgtx_flash.ld:56: syntax error
collect2.exe: error: ld returned 1 exit status

Issue has been fixed after creating NEW project from the beggining

Hello @OmidES @streb2001 @RichardS1 @LPetr.1 @luoqi 

It seems to be solved on my side. I've migrated the file shared by the @OmidES (the one using the STM32CubeMX VB6.12.1) and it seems to be working fine.

Best Regards.

If it compiles but chooses the wrong RAM then surely it is not fixed?

[OmidES]

Hard to say. In my case, DTCMRAM is not the right RAM for my application.

 

[OmidES]

I think I found a solution to also choose the desired RAM in CubeMX. This has been added in CubeMX v6.13.

To do this, navigate to Tools > Memory Management, where you can select the type of RAM you want to use.

Make sure to enable the following options:
- "Apply Application Regions to Peripherals"
- "Apply Application Regions to Linker Files"
- and check the "Default Data Region" box.

Also, ensure that you delete the existing .ld file in your project folder. Otherwise, the .ld file will not be updated.

I have highlighted the important steps for your attention in the figure below:
