STM32CubeIDE empty STM32 project MCU change

[markorman]

How can I change the MCU used in the project which was created as STM32 projct and "empty project" not CUBEMX.

The Option fo MCU is greyed out in Tool Settings.

Even when choosing empty project in the "New -> STM32 project" flow you still use the MCUFinder to choose a target.

It's listed under known problems (RN0114) that "STM32CubeIDE does not support switching from one MCU to another once the project is created".

If you have resources you want to move then you'll need to create a new empty project and do it manually.

It's still possible but by manual editing of the project (.cproject, .project and some files unter .settings subdir) files and knowing what to replace.
