Nucleo-H7S3L8 USB HS Timeout on USB_CoreReset function

Hello,

I am trying to use the USB HS on the Nucleo-H7S3L8 dev board.

I was using the USB HS on the STM32H7A3ZI, it was using the physical layer but limited to FS, and it was easy to configure, but i need to change boards to have the HS USB.

The ioc is configured with basics only:

Rcc - HSE - Crystal/ceramic resonator

USB_OTG_HS - Device_only

USB_Device - Virtual COM Port

The clock configuration does not show conflicts and USBOHS is 60MHz.

The project was imported from a template and has Boot project only.

When debugging the code the function  MX_USB_DEVICE_Init() gives timeout, more specifically on the USB_CoreReset function.

Thanks for your help!

    @FBL I am still not able to compile/flash the cdc_standalone. I am still failing to understand how to flash both elf files and debug the application one.
    Nevertheless, i was able to crate a project with USB HS working!
    My project only has the Boot subproject.

    I will leave the IOC file attached for future reference.

    It has SBS activated with -  HSLV for XSPIM2 enabled
    PWR activated - with USB regulator ticked and USB_HS_REGEN enabled
    USB_DEVICE is activated and configured as VCP
    I also changed some settings on RCC and on Cortex M7 Boot

    After applying these changes the USB code was not timing out. Right now i only have some issues when debugging because the VCP is not showing on the device manager. But when running the code without the debug the VCP shows and i can communicate with the device.

    Hello @andr3 

    Have you tried the following example STM32CubeH7RS/Projects/NUCLEO-H7S3L8/Applications/USB_Device/CDC_Standalone at main · STMicroelectronics/STM32CubeH7RS (github.com)

    Otherwise, I suggest you share your project. Remember, to guarantee a correct operation for the USB OTG_HS peripheral, the AHB frequency must be higher than 30 MHz.

    Hello @FBL i edited my post to include project on attachment. I have tried to import the cdc standalone to the STM32CubeIDE but it kept giving me an error copying(image). So i opened it manually. I am still not sure how to compile this multi project and upload to the board eve following the um3294 steps. Thanks for your help!

    Hi @andr3 

    This is known issue, similar issue in this post Fail to perform local copy - STMicroelectronics Community

    Try to run the example manually from direct path

    Yes i can import it manually, but can you help me upload both boot and application to the board? It is build each one individually and running each one? Or is there a command to build and upload both at the same time?

    @andr3 Check HSLV1 and HSLV2 option bytes. They should be enabled.

    Then, depending on your toolchain follow the readme to flash the code.
