I can not get usart2 working in asynchronous mode on STM32f767zi-nucleo.


My clock configuration function contains


PeriphClkInitStruct.Usart2ClockSelection = RCC_USART2CLKSOURCE_PCLK1;


In main() I call 


static void MX_USART2_UART_Init(void)

huart2.Instance = USART2;
huart2.Init.BaudRate = 115200;
huart2.Init.WordLength = /*UART_WORDLENGTH_7B*/UART_WORDLENGTH_8B;
huart2.Init.StopBits = UART_STOPBITS_1;
huart2.Init.Parity = UART_PARITY_NONE;
huart2.Init.Mode = UART_MODE_TX_RX;
huart2.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart2.Init.OverSampling = UART_OVERSAMPLING_16;
huart2.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart2.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
if (HAL_UART_Init(&huart2) != HAL_OK)
_Error_Handler(__FILE__, __LINE__);



When I try to send something to USART2 with HAL_UART_Transmit I get return code HAL_OK, but I can't  see anything on serial port.


Can you give me an advice?


Thank you
