STM32CubeMX Makefile/CMake generation failure STM32U5*

[audiofish]

Hi,

I am trying to generate a project using STM32CubeMX v6.11.1 Linux using the NUCLEO-U5A5ZJ-Q project template.

I am happy to use either a Makefile or a CMake based build, but unfortunately both have issues.

 

If I select a Makefile build, and click Generate, the project is created, but the stdout log of STM32CubeMX provides this warning:

 

No such linker file: /home/user/STM32Cube/Repository//STM32Cube_FW_U5_V1.5.0//Drivers/CMSIS/Device/ST/STM32U5xx/Source/Templates/gcc/linker/STM32U5a5xx_FLASH.ld

 If I try to build with make, I see this issue reflected in the build:

If I instead select a CMake build, the following warning is shown when I hit Generate:

The log from STM32CubeMX shows a similar fault:

It appears that the upstream STM32Cube repository that should contain these files (https://github.com/STMicroelectronics/cmsis_device_u5/tree/3abe881508869a9eb9dff7efab3638528a9332e3/Source/Templates/gcc/linker) does not contain the corresponding linker scripts for this platform. Do you have an estimate when these support will be complete? I have a development board arriving shortly and it would be a shame to not be able to start development because linker scripts are not available.

Thank you for your help.

Hello @audiofish 

Thank you for posting!

Actually, the support for the CMake toolchain in STM32CubeMX V6.11.1 is only for single-context series (mono-core, without Arm® TrustZone®(a)). However, since NUCLEO-U5A5ZJ-Q is based on Arm Cortex-M33 MCU with TrustZone, CMake is not supported in this case.
The support for this feature will be included in the upcoming release that will be published as soon as possible.

Dear ST,

In our current development context, we are migrating to a CMake + Visual Studio Code based build environment. We are working with USBX and ThreadX on STM32U5A5ZJ-Q (Nucleo-U5A5ZJ-Q board) and would like to rely on official CMake generation support moving forward.

Could you please let us know when official CMake support for STM32U5A5ZJ-Q will be released?

Thank you in advance.

Hello @Abhimanyu 

Starting from version 6.12.0, STM32CubeMX supports the CMake toolchain with multicontext, Arm® TrustZone®(a), and multicore series.

Hello @Souhaib,

Thank you again for the clarification.

I have now tested this using STM32CubeMX v6.14.1 with STM32U5A5ZJTxQ selecting CMake as the toolchain after enabling only USBX and ThreadX (no additional configuration).

Unfortunately, the code generation still fails with the message:

"The code is successfully generated under [path] but CMake project generation have a problem."

Given that you mentioned multicontext and TrustZone support is available from v6.12.0 onward, could you please confirm whether:

CMake support for STM32U5 with USBX + ThreadX is indeed complete?

Or are there known limitations when these middleware components are enabled?

Any guidance on resolving or working around this would be greatly appreciated.

Best regards,
Abhimanyu
