MCSDK v6.41 - Keep getting "The following has evaluated to null or missing" error during code generation

Hello and good day.

When using my custom board, I am facing "The following has evaluated to null or missing" errors during code generation. I have tried a few variation of custom boards but I can't seem to solve the issue. FYI, this doesn't happen when generating code using ST evaluation boards.

Is this an issue from my side?

I am using the latest MCSDK v6.41 and STM32CubeMX 6.15.

I have attached my project file for reference.

Edit: I am using STMC Board Designer Version: 1.2.1 and I just uploaded the board design.

Hi fmariz, as described into the "known Limitations/For 6Step algorithm" section of the "Release Notes" for the ST MCSDK 6.4.1, the supported series for the 6step algorithm are the following:

  • Supported series are: STM32C0xx, STM32F0xx. STM32F3xx, STM32F4xx, STM32G0xx and STM32G4xx.

Please refer to Release Note available through "Workbench tool">About>Documentations>Release Notes> link

Best regards.

Thanks for the confirmation. I hope ST will remove the limitation in the next release. Also I hope that STM32H523 series will be added into the supported MCU list in the Board Designer.
