Stm32CubeIDE for Visual Studio Code - The project conversion tool doesn't copy over assembly files, .s files.

As the title describes, the conversion tool to convert Stm32CubeIDE projects over to Visual Studio Code seems to work. Apart from the fact that, at least in my case, it failed to copy over the assembly files, .s files, in the project.

 

Which led to build errors, specifically thumb mode errors.

Just posting this here so that it may help others. Not quite sure how best else to let others know.

Thanks ​@ad101, for your screenshot. It helped a lot in understanding the root cause.

This is only a matter of file extension: the exporter considers only .s files as assembler sources, not .S files.

You can confirm this on your side by simply renaming the assembly sources to *.s.

I created an internal ticket to address this bug. Thanks again for helping improve the robustness of our extensions.
