STM32Cube AI Studio locked .cproject bug

I am trying to generate a program a run using STM32Cube AI Studio and the STM32N6570-Dev Kit, but am running into an issue with the run failing due to a resource busy or locked (the .cproject). 

 

Some steps I’ve already taken:

  1. Closed all other STM programs (IDE, Programmer, MX)
  2. Completely deleted and made a new project
  3. Confirmed all ST programs (IDE, Programmer, MX) are up to date by cleaning and re-installing from ST website
  4. Confirmed all ST programs are linked to the AI Studio and confirmed they’re all downloaded in their default location.
  5. Restarted my PC.

Notes:

  • I am on Windows 11, Version 10.0.26200 Build 26200
  • Model = ST YOLO-X Nano - Person Detection. Source:

    • Pre-trained model from ST Model Zoo

    • Path: stm32ai-modelzoo/object_detection/st_yoloxn/ST_pretrainedmodel_public_dataset/coco_2017_person/st_yoloxn_d033_w025_256/

Hi ​@joel_,

 

This is a strange issue. 

Maybe a STM32 tool has kept the cproject file opened somehow.

Did you try to reboot your pc?

 

Have a good day,

Julian
