N25Q128A13EF840F External Flash read write example

Hi,

I am new to QSPI. I working with stm32f469 disco that comes with external flash N25Q128A13EF840F. I had done the GUI part now I need to store data to external flash but I don't know how to do it. I had initialized qspi with STMCUBE default initialization. Any help

below is the way i had initialized

static void MX_QUADSPI_Init(void)
{
 
 /* USER CODE BEGIN QUADSPI_Init 0 */
 
 /* USER CODE END QUADSPI_Init 0 */
 
 /* USER CODE BEGIN QUADSPI_Init 1 */
 
 /* USER CODE END QUADSPI_Init 1 */
 /* QUADSPI parameter configuration*/
 hqspi.Instance = QUADSPI;
 hqspi.Init.ClockPrescaler = 1;
 hqspi.Init.FifoThreshold = 1;
 hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_HALFCYCLE;
 hqspi.Init.FlashSize = 24;
 hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_5_CYCLE;
 hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;
 hqspi.Init.FlashID = QSPI_FLASH_ID_1;
 hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE;
 if (HAL_QSPI_Init(&hqspi) != HAL_OK)
 {
 Error_Handler();
 }
 /* USER CODE BEGIN QUADSPI_Init 2 */
 
 /* USER CODE END QUADSPI_Init 2 */
 
}
