USB HS doesn't work with TouchGFX ?

Hello,

I am using an STM32F769I-DISCO board to implement USB HS in my TouchGFX project, but it is not working as expected. I have already tested USB functionality with FreeRTOS CMSISv2 without TouchGFX, and it works fine. However, when I try to run both TouchGFX and USB HS host (MSC) together, the application state remains stuck at APPLICATION_START when the USB disk is connected and never make transition to APPLICATION_READY.

I have tried adjusting the priorities of the USB and TouchGFX tasks and increased the stack size for the USB task, but the issue persists.

Any suggestions to help get both working together properly would be greatly appreciated ?

Best regards.
