For STM32H563IIK6 USB Virtual configuration hanging in the code.

[gatadivijay]

On Cubex Generated code, we added Virtual Com Port code.

But the code is going to Hard fault handler in USB_ActivateEndpoint. 

HAL_StatusTypeDef USB_ActivateEndpoint(USB_DRD_TypeDef *USBx, USB_DRD_EPTypeDef *ep)
{
HAL_StatusTypeDef ret = HAL_OK;
uint32_t wEpRegVal;

wEpRegVal = PCD_GET_ENDPOINT(USBx, ep->num) & USB_EP_T_MASK;

Please can you suggest any thing is wrong.

Hi @gatadivijay Can you please share with us endpoint PMA configuration ??.

This is the PMA Configuration.

void MX_USB_PCD_Init(void)

{

/* USER CODE BEGIN USB_Init 0 */

hpcd_USB_DRD_FS.pData = &hUsbDeviceFS;

/* USER CODE END USB_Init 0 */

/* USER CODE BEGIN USB_Init 1 */

/* USER CODE END USB_Init 1 */

hpcd_USB_DRD_FS.Instance = USB_DRD_FS;

hpcd_USB_DRD_FS.Init.dev_endpoints = 8;

hpcd_USB_DRD_FS.Init.speed = USBD_FS_SPEED;

hpcd_USB_DRD_FS.Init.phy_itface = PCD_PHY_EMBEDDED;

hpcd_USB_DRD_FS.Init.Sof_enable = DISABLE;

hpcd_USB_DRD_FS.Init.low_power_enable = DISABLE;

if (HAL_PCD_Init(&hpcd_USB_DRD_FS) != HAL_OK)

{

Error_Handler();

}

Error_Handler();

Error_Handler();

Error_Handler();

Error_Handler();

/* USER CODE END USB_Init 2 */

}

USBD_StatusTypeDef USBD_LL_Init(USBD_HandleTypeDef *pdev)

{

pdev->pData = &hpcd_USB_DRD_FS;

HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData , 0x00 , PCD_SNG_BUF, 0x40);

HAL_PCDEx_PMAConfig((PCD_HandleTypeDef*)pdev->pData , 0x80 , PCD_SNG_BUF, 0x80);

return USBD_OK;

}

I recommande you to put the snippet code in (Insert/Edit code sample) to be more lisible for other user in community.

Secand you can try with endpoints PMA config of STM32G0 since it is the same DRD IP.

I tried second one but it still hangs at same point. I will try fist one now and let you know.
