ST32F469I AU1 Serial port issue on Cube IDE

[Chris1001Z]

Hi All 

I am having difficulty getting the serial to work through the STlink on the STM32F469I AU1 (MB1189B) version. 

I have tried all the suggestions in the previous posts on the forms. The uart is set with the correct pins according to the schematic of the MB1189B (Uart3 PB10, PB11). I have tried numerous serial monitors all settings were correct and still nothing. Is there something different in the configuration of this version of the PCB that I am missing?  I am really at a loss as to why this isn't working any suggestions Would be appreciated.

Also, find attached Code below were i try every port on the PCB. 

main.c

/* USER CODE BEGIN PV */

uint8_t tx_buffer1[10] = "UART1!!\n\r";

uint8_t tx_buffer2[10] = "UART2!!\n\r";

uint8_t tx_buffer3[10] = "UART3!!\n\r";

uint8_t tx_buffer4[10] = "UART4!!\n\r";

uint8_t tx_buffer5[10] = "UART5!!\n\r";

uint8_t tx_buffer6[10] = "UART6!!\n\r";

/* USER CODE END PV */

int main(void)

{

  /* USER CODE BEGIN 1 */

  HAL_UART_Transmit(&huart1, tx_buffer1, 10, HAL_MAX_DELAY);

  HAL_UART_Transmit(&huart2, tx_buffer2, 10, HAL_MAX_DELAY);

  HAL_UART_Transmit(&huart3, tx_buffer3, 10, HAL_MAX_DELAY);

  HAL_UART_Transmit(&huart4, tx_buffer4, 10, HAL_MAX_DELAY);

  HAL_UART_Transmit(&huart5, tx_buffer5, 10, HAL_MAX_DELAY);

  HAL_UART_Transmit(&huart6, tx_buffer6, 10, HAL_MAX_DELAY);
