Question

Import entire hierarchical project structure?

 Hello, 

When I try to create a project, I get a message saying that the project already exists in the workspace.
However, I don't have such a project anywhere on my PC.

 

 

 

 

 

 

 

 

When I select Yes, I am asked if I want to delete an old project (which doesn't actually exist). When I check the box and select OK, I get a success message, but it looks different from other healthy projects in Explorer and I can't build it.

 

 

 

 

 

 

 

 

 

 

I uninstalled CubeMX and CubeIDE and deleted as many related folders as possible.


C:\Users\<UserFolder>\.stm32cubeide
C:\Users\<UserFolder>\.stm32cubemx
C:\Users\<UserFolder>\.stm32cubeup
C:\Users\<UserFolder>\.stmcufinder
C:\Users\<UserFolder>\STM32Cube
C:\Users\<UserFolder>\STM32CubeIDE
C:\Users\<UserFolder>\STMicroelectronics
C:\Users\<UserFolder>\AppData\Local\Programs\STM32CubeMX
C:\ST

 

Reinstalling CubeMX and CubeIDE and creating a project again resulted in the same problem.
Where is the information for this non-existent project stored?

Best regards, 
Gotoda

Hello ​@gocchan 

Thanks for reporting this issue in STCommunity,

Could you click  ”NO” when you get the message saying that the project already exists in the workspace, and check if the project is imported correctly?
