FreeRTOS and USB givers Hard Fault in H743 MCU

[RAbdu.1542]

Dear Sirs

I am having a problem using FreeRTOS and USB on H7 series MCU. The IDE gives “Hard Fault” when I debug the project. See image below.

The environments are :

STM32CubeIDE:  Version: 1.14.0, Build: 19471_20231121_1200 (UTC)

Target: NUCLEO-H743ZI2

Enclosed herewith are the two “ioc” files.

FreeRTOS_USB1.ioc is for the project without initialization to the USB and it is working fine.

FreeRTOS_USB.ioc is for the project with the initialization to the USB and it is giving my Hard Fault.

Your help and assistance are highly appreciated.

Best Regards

Hi @RAbdu.1542 

Do you still have the same issue if yes, please consider attaching your IOC file.

Hi FBL

Thank you for the reply. Yes, I am still having the problem. I already attached the IOC files above.

Increasing the MINIMA_STACK_SIZE can solve the problem.

Hi @RAbdu.1542 

To address the issue you're facing, I recommend the following steps:

1. Update CubeMX to latest version.
2. Compare generated code from working and not working IOC file.
3. This issue might be linked to CMSIS V1 as you may not increase the stack size for USB task.
