STM32CubeMX2 Failing to Start

[Martin Jay McKee]

I am running STM32CubeMX2 (1.1.1) on a Mac (Tahoe 26.6.2) and I did (with some difficulty) get it installed and running. I configured a MCU (STM32C552CEUx) and generated an STM32CubeIDE project. No problem.

I went back and copied the .ioc2 file, renamed it, and went to configure a different system. Everything was going fine until I tried to configure some new pins after adding middle ware (FreeRTOS and basic_stdio). I could not select pin functions in the graphic mode, table mode, or through activating the associated peripheral (I2C2) and updating the GPIO there. So, I closed CubeMX2 and restarted. Now I get the splash screens showing fine, but when they go away, I just get the spinning timer in the upper-left of an empty screen.

 

In file, I can click Close Window which it will dutifully do, but then I have nothing. In view, Reload and Force Feload do not seem to do anything.  

 

Any thoughts as to how to debug this would be greatly appreciated.

Hi ​@Martin Jay McKee, and welcome to STCommunity

Thank you for reporting this issue. To help us investigate and reproduce it, could you please share the following if possible?

• Both .ioc2 files if available: the original file and the copied/renamed one
• An Issue Reporter export (logs) for the current project and environment
• Screenshots that may help with further investigation

Any details you can share will be very helpful for us to reproduce the problem and continue the investigation.

Best Regards
