HAL_UART_Receive_IT is not working

Originally a reply in this thread - split as a separate question.

Hello 

My blocking mode is working with "HAL_UART_Receive(&huart4, temp, 1, 100);"

Nonblocking mode is not working

Can you suggest anything to check?

I have defined as said

/* USER CODE BEGIN 2 */

HAL_UART_Receive_IT(&huart4, temp, 1);

/* USER CODE END 2 */

and

/* USER CODE BEGIN 4 */

void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
  HAL_UART_Receive_IT(&huart4, temp, 1);
  HAL_UART_Transmit(&huart4, temp, 1, 100);
}

/* USER CODE END 4 */

Andrew Sir,

Apologies from my side and its been my pleasure for your valuable feedbacks.

Actual Problem is my BOOT mode pin it was not connected properly to the ground, somehow I got wrong short-link which has case but no short-link inside.

Things are working perfectly fine. Again thanks
