STEVAL-STWINBX1 – “Automatic build and run failed” during Validation on Target

Dear ST Technical Support Team,
I am currently developing a voice recognition application on the STEVAL-STWINBX1. I trained a classification model using the notebook:
Utilities\AI_Resources\TrainingScripts\UltrasoundClassification\UltrasoundClassification.ipynb
In the notebook/off-target evaluation, the model achieves >90% accuracy, but after deploying to the MCU the recognition accuracy becomes very low.
To investigate, I used STM32CubeMX → Validation on Target. However, the validation process fails with the message: “Automatic build and run failed” (Automatic Validation on the target)
Thank you for your help. I look forward to your guidance on resolving the validation failure and improving on-MCU accuracy.
Best regards,
