Stuck at USB Core Soft Reset

[smartinez]

I am trying to get USB High Speed running on my board, In the USB Core Soft Reset function, my code keeps on getting stuck in the do while loop that I have shown below. I have went through all the forum posts related to this and there has been no solution that has resolved this issue. The microcontroller series on this board is STM32U5A5RJT6. I would appreciate any guidance. Thank you!

  /* Core Soft Reset */
  USBx->GRSTCTL |= USB_OTG_GRSTCTL_CSRST;

  do
  {
    count++;

    if (count > HAL_USB_TIMEOUT)
    {
      return HAL_TIMEOUT;
    }
  } while ((USBx->GRSTCTL & USB_OTG_GRSTCTL_CSRST) == USB_OTG_GRSTCTL_CSRST);

  return HAL_OK;
}

Hi @smartinez 

Did you take a look to this FAQ: Troubleshooting a USB core soft reset stuck?

Hello, 

Thank you for your response. Yes, we have taken a look at that article and have tried all of the solutions mentioned, but we will try again. Is there anything else that could be causing the issue?

Thank you so much!

I have attached the exported STM32 project below, hopefully it can help us determine the root cause of the issue.

Hi @smartinez 

I suggest you start with this example.

Hi @smartinez 

Based on your firmware, it seems you have multiple changes in your hardware setup you need to consider before.
