The “Generate under Root” option is grayed out and cannot be changed.

Hi 

I created a new project in STM32CubeIDE, but in Project Manager → Project, the “Generate under Root” option is grayed out and cannot be changed. What’s the reason for this?

Hello @Adams ,

First let me thank you for posting.

When you create or open a project directly in STM32CubeIDE, it automatically manages the code generation paths and structure.
CubeIDE integrates CubeMX internally, so it locks the [Generate Under Root] option to maintain consistent folder management.

You will only see it enabled if you run standalone STM32CubeMX

Thanks.

Mahmoud
