How to: CubeMX + FreeRTOS + CrossStudio

[KKjel.1]

I am trying to add FreeRTOS support in an STM32CubeMX project, and import into Rowley CrossStudio.

In CubeMX, I have tried all toolchains, and then import them into CrossStudio.

But none of them works, and I get a ton of compiler errors.

When generating an STM32Cube IDE project (GCC/Eclipse), and import into CrossStudio, I get problems with newlib library, which are impossible to solve.

Has anyone experience with generating a CubeMX project with FreeRTOS enabled, and import into Rowley CrossStudio?

I have made projects without FreeRTOS support, and importing into CrossStudio works fine.

But when adding FreeRTOS, things gets messy...

Thanks !

Hello @Kåre Kjeldsen​ ,

Thanks for your feedback,

Did you get any error when you compiled your project using CubeIDE and before importing it to CrossStudio ?, if so could you please share your .ioc file?

Thanks,

Sara.

Hi Sara

Yes, I do get an error when creating an STM32Cube IDE project:

../Core/Src/main.c:156:26: error: 'PWR_DIRECT_SMPS_SUPPLY' undeclared (first use in this function)

When I comment out the line in main.c, it compiles OK.

Hi Sara

I attached the .ioc file to the mail.

But let's try if I can attach it here:

Hello @Kåre Kjeldsen​ ,

Compilation error when using an STM32H730ZBT

../Core/Src/main.c:156:26: error: 'PWR_DIRECT_SMPS_SUPPLY' undeclared (first use in this function)

This is a known issue and it is already reported to the dev team. Please replace 'PWR_DIRECT_SMPS_SUPPLY' with 'PWR_LDO_SUPPLY', it should compile fine.

Sorry for the inconvenience it may cause,

Hi Sara

OK, thanks I will do that.

This was actually a secondary problem, to get to the original problem: To create a CubeMX project with FreeRTOS enabled, and import into Rowley CrossStudio.

When creating a CubeMxIDE project, with FreeRTOS support, there is a warning to enable "USE_NEWLIB_REENTRANT". When I do this, I get deep problems with this newlib, when importing into CrossStudio.

If i do not enable it, I get a bit closer to succes, but then I get some errors because <stddef.h> is not included correctly.

Is this issues you know ?

Hello @Kåre Kjeldsen​ ,

Could you please share your project?

Thanks,

Regarding the missing stddef, I can add #include <stddef.h> in the sysmem.c file, and then it compiles.

I am not sure if this file is a file maintained and distributed by ST ?

"USE_NEWLIB_REENTRANT" problem: I have decided to NOT use this define, and I can now compile OK.

Yes, of course

Hello @Kåre Kjeldsen​ ,

I couldn't reproduce the issue so I advise you to use one of CubeMX supported Toolchains (CubeIDE, EWARM, MDK ARM), it is more guaranteed.
