I have created a ui to that i am able to upload on the custom board(STM32H750VBT6) which i can successfully Debugging using IDE but display is empty.I dont know where I am wrong.
I attached the library that I am using below.I have taken library from this GitHub

with this pinout

int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MPU Configuration--------------------------------------------------------*/
MPU_Config();
/* MCU Configuration--------------------------------------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_DMA_Init();
MX_SPI1_Init();
MX_TIM3_Init();
MX_CRC_Init();
MX_TouchGFX_Init();
/* USER CODE BEGIN 2 */
// SCB_DisableICache();
// SCB_DisableDCache();
Displ_Init(Displ_Orientat_0); // initialize display controller - set orientation parameter as per TouchGFX setup
touchgfxSignalVSync(); // ask display syncronization
Displ_BackLight('I');
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
if(Touch_GotATouch(0))
touchgfxSignalVSync();
/* USER CODE END WHILE */
MX_TouchGFX_Process();
/* USER CODE BEGIN 3 */
HAL_GPIO_WritePin(GPIOE, GPIO_PIN_3,GPIO_PIN_SET);
HAL_Delay(1000);
HAL_GPIO_WritePin(GPIOE, GPIO_PIN_3,GPIO_PIN_RESET);
HAL_Delay(1000);
}
/* USER CODE END 3 */
}
