Simple UART problem STM32H753

Hi,
I'm relatively new to the STM32 world and I'm becoming frustrated that I can't make a simple UART work. No DMA, no interrupts just trying to send bytes out of the UART and then receive them. Here is my setup code:

void UART7_Init(void)
{

	GPIO_InitTypeDef GPIO_InitStruct;

		HAL_Init();


	 /* Peripheral clock enable */
 __HAL_RCC_UART7_CLK_ENABLE();
 __HAL_RCC_GPIOF_CLK_ENABLE();

 /**UART7 GPIO Configuration
 PF6 ------> UART7_RX
 PF7 ------> UART7_TX
 PF8 ------> UART7_RTS
 PF9 ------> UART7_CTS
 */
 GPIO_InitStruct.Pin = U7_PAY_RX_SPI5_NSS_Pin|U7_PAY_TX_SPI5_SCK_Pin;
 GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
 GPIO_InitStruct.Pull = GPIO_NOPULL;
 GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
 GPIO_InitStruct.Alternate = GPIO_AF7_UART7;
 HAL_GPIO_Init(GPIOF, &GPIO_InitStruct);


 huart7.Instance = UART7;
 huart7.Init.BaudRate = 115200;
 huart7.Init.WordLength = UART_WORDLENGTH_8B;
 huart7.Init.StopBits = UART_STOPBITS_1;
 huart7.Init.Parity = UART_PARITY_NONE;
 huart7.Init.Mode = UART_MODE_TX_RX;
 huart7.Init.HwFlowCtl = UART_HWCONTROL_NONE;
 huart7.Init.OverSampling = UART_OVERSAMPLING_16;
 huart7.Init.OneBitSampling = UART_ONEBIT_SAMPLING_DISABLED;
 huart7.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;

 	if(HAL_UART_Init(&huart7) != HAL_OK)
 	{
 		asm("bkpt 255"); // Just for degugging
 		Error_Handler();
 	}

 /* UART7 interrupt Init */
 //HAL_NVIC_SetPriority(UART7_IRQn, 5, 0);
 //HAL_NVIC_EnableIRQ(UART7_IRQn);
 /* USER CODE BEGIN UART7_MspInit 1 */

 /* USER CODE END UART7_MspInit 1 */
 }

And here is the actual transmit code:

do
	{
	drv_led_toggle(DRV_LED_ID_AMBER);
	HAL_UART_Transmit(&huart7, receiveBuffer, sizeof(receiveBuffer), TIMEOUT);
	HAL_Delay(300);
	//HAL_UART_Receive(&huart7, receiveBuffer, 1, TIMEOUT);
	drv_led_toggle(DRV_LED_ID_AMBER);
	HAL_Delay(300);

	if(UART7->ISR & (1<<5))
	 {
		HAL_UART_Receive(&huart7, receiveBuffer , 1 /*sizeof(receiveBuffer)*/, TIMEOUT);
	 }

	if(i%2)drv_led_toggle(DRV_LED_ID_AMBER);


	} while(i<5);

I'm pretty sure that it's something simple and I'm just missing it. Any advice is appreciated.

Thanks.
