Posted on December 21, 2016 at 16:35When I generate a project with USB CDC Device Class and FreeRTOS, enumeration fails because the clock to the USB peripheral is not enabled before calling MX_USB_DEVICE_Init(). If I insert the code as follows
void StartDefaultTask(void const * argument)
{
/* init code for LWIP */
MX_LWIP_Init();
__HAL_RCC_USB_OTG_FS_CLK_ENABLE(); <----- INSERT THIS LINE
/* init code for USB_DEVICE */
MX_USB_DEVICE_Init();
/* USER CODE BEGIN 5 */
/* Infinite loop */
for(;;)
{
osDelay(1);
}
/* USER CODE END 5 */
}
in the Default Task it works like a charm. Please consider fixing that as it took me quite some time to figure out what was wrong.
