Unable to access QuadSPI Flash 2 with stm32h747i

[ujwal_kumar_N_L]

Hi im currently using STM32H747I EVK board and working on QSPI ,im able to perform all the QSPI operations in FLASH1 but when u configure it as the FLASH2 nothing works .

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 = 25;
hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_8_CYCLE;
hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;
hqspi.Init.FlashID = QSPI_FLASH_ID_2;
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 */

}

System clock is 64MHz i have also configured the Pins.

Hello @ujwal_kumar_N_L and welcome to STCommunity 🙂,

Could you please specify which STM32CubeMX version are you using? Please try with the latest version: STM32CubeMX 6.10.0

Do you have the same issue when you using  QSPI_MemoryMappedDual example, without generating the code with STM32CubeMx? 

Thank you.

Do you mean the STM32H747I-EVAL board of the STM32H747I-DISCO board?

What MICRON part is populated on the board? What pins are you using? Is SB6 open or closed?
