Project Explorer icons - what does slash mean?

Likely a multi-core project where you've selected the M4 core as the build target..​

Thanks - that makes sense.

The problem is that STM32CubeH7 example projects does not exist for CubeIDE.

The package only contains example projects targeting EWARM / MDK-ARM / SW4STM32.

For single-core STM32 devices, CubeIDE offers an import/convert wizard that does the job of converting the build configurations in the SW4STM32 project files into CubeIDE equivalent build configurations. If customer has set very specific options/customizations the wizard will not be able to translate these options. But a log-file is produced mentioning all options that the wizard was not able to translate so that it should be simple to manually make the appropriate fixes.

The wizard actually does a pretty good job in 95% of the cases!

Here comes the but. But, the example projects for H7 dual-core targeting SW4STM32, was setup as "one single Eclipse project" containing both "core projects".

Another approach was chosen in CubeIDE where any dual-core or TZEN=1 project is setup as a hierarchical project:

• Project_shared_code
  • Project_CM4
  • Project_CM7

The import/convert wizard cannot translate one single SW4STM32 project into multiple STM32CubeIDE project structure.

The wizard will not generate any error, but multiple issues in the convert log-file. And the converted project will only contain a build configuration for the CM4.

Could you add a CM7 build configuration manually to target another core with the same project?

Nope, unfortunately not. Maybe you could if you hack the "natures" in the .project-file, but now we are clearly moving into unsupported areas.

What would be the recommendation to proceed?

• Option1: Either rely on this app note, chapter 2.3 to port the project manually from SW4STM32 to CubeIDE:
  • https://www.st.com/resource/en/application_note/an5361-getting-started-with-projects-based-on-dualcore-stm32h7-microcontrollers-in-stm32cubeide-stmicroelectronics.pdf
• Option2: Wait until later this year (November-ish) when the STM32CubeH7 package will contain STM32CubeIDE projects for all examples.

I hope that at least clarifies the dead-ends, the options and the status moving forward.

Thanks for your answer. I have enough at this point I should be able to port to a new project. If you create a project without selecting an example, the project gets created correctly and from there it should be possible to move files around in the new project, I would think.
