Hello to all,
I have some problems running HS USB MSC device type on a STM32U5 using AZURE.
After the program is running on my board, I see this new device on the Device Manager of my PC:"Azure RTO USBX storage dev USBdevice".
But there are no hard drives visible in Explorer. I'm using a exFAT formatted SDCard of about 256GByte. The initialization of the SDCard completed well, and I have the IRQ for the DMA transfer fired without problems.
I added this command inside the file usb_otg.c :
void MX_USB_OTG_HS_PCD_Init(void)
{
/* USER CODE BEGIN USB_OTG_HS_Init 0 */
__HAL_RCC_SYSCFG_CLK_ENABLE();
/* USER CODE END USB_OTG_HS_Init 0 */
And I start the USB thread like this:
static VOID app_ux_device_thread_entry(ULONG thread_input)
{
/* USER CODE BEGIN app_ux_device_thread_entry */
TX_PARAMETER_NOT_USED(thread_input);
MX_USB_OTG_HS_PCD_Init();
HAL_PCDEx_SetRxFiFo(&hpcd_USB_OTG_HS, 0x100);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 0, 0x60);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 1, 0x60);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_OTG_HS, 2, 0x60);
/* USER CODE END USB_Device_Init_PreTreatment_1 */
/* initialize the device controller driver*/
_ux_dcd_stm32_initialize((ULONG)USB_OTG_HS, (ULONG)&hpcd_USB_OTG_HS);
/* Start device USB */
HAL_PCD_Start(&hpcd_USB_OTG_HS);
}
And if I put in pause randomly the program, I see that it is always inside this function: _ux_device_stack_transfer_request.
I posted on github some screenshot, files and the complete project: I hope to post the solution too, to help other people.
Someone can help me? Where am I wrong?
TIA
Clemente
