How do aI specify the .ioc file for X-CUBE-53L3A2?

[charles23]

I have added the X-CUBE-53L3A2 software package to STM32CubeIDE and successfully built and run the SimpleRanging sample application. I now want to make changes to the STM32F401 pin assignements (actually, add a second UART).

When I click on the NucleoF401RE_53LX_Expansion.ioc file I get this error:

Invalid Input: Must be project's active .ioc file.

Project's 'SimpleRanging' active one is 'SimpleRanging.ioc' file

AFAIK there is no file 'SimpleRanging.ioc'

How can I fix this, and where do I look to understand how these .ioc files are used within STM32CubeIDE?

BTW - I am able to create new projects using .ioc files, including a new project using the existing NucleoF401RE_53LX_Expansion.ioc file

Hmmm.... so far I have not found a fix to this. (I would still like an answer!). Instead I have created a new project (File > New > STM32 project from an Existing STM32CubeMX Configuration File) and referenced the NucleoF401RE_53LX_Expansion.ioc file from the X-CUBE-53L3A2 project. That allowed me to open the .ioc file and make changes.

To get the X-CUBE-53L3A2 example running I then had to import a load of files from the X-CUBE-53L3A2 project and mess around with the resulting compiler errors, but I did get it running....

Charles -

That .ioc file is created by the code that configured your Nucleo board.

I really don't know much about it. Granted I use it - but I don't know much about it.

I suggest you post this to the STM32 community page.

They know a lot more than I do.
