How to configure SDRAM in STM32H747i-DISCO discovery board?

[Pavankumar1_]

I am using STM32H747i-DISCO board, I am trying to configure external SDRAM and board is having IS42S32800G-6BLI external SDRAM. But it will show hard fault error. Below shown code will be my configuration.

void MX_FMC_Init(void)
{

/* USER CODE BEGIN FMC_Init 0 */

/* USER CODE END FMC_Init 0 */

FMC_SDRAM_TimingTypeDef SdramTiming = {0};

/* USER CODE BEGIN FMC_Init 1 */

/* USER CODE END FMC_Init 1 */

/** Perform the SDRAM1 memory initialization sequence
*/
hsdram1.Instance = FMC_SDRAM_DEVICE;
/* hsdram1.Init */
hsdram1.Init.SDBank = FMC_SDRAM_BANK2;
hsdram1.Init.ColumnBitsNumber = FMC_SDRAM_COLUMN_BITS_NUM_8;
hsdram1.Init.RowBitsNumber = FMC_SDRAM_ROW_BITS_NUM_13;
hsdram1.Init.MemoryDataWidth = FMC_SDRAM_MEM_BUS_WIDTH_32;
hsdram1.Init.InternalBankNumber = FMC_SDRAM_INTERN_BANKS_NUM_4;
hsdram1.Init.CASLatency = FMC_SDRAM_CAS_LATENCY_1;
hsdram1.Init.WriteProtection = FMC_SDRAM_WRITE_PROTECTION_DISABLE;
hsdram1.Init.SDClockPeriod = FMC_SDRAM_CLOCK_DISABLE;
hsdram1.Init.ReadBurst = FMC_SDRAM_RBURST_DISABLE;
hsdram1.Init.ReadPipeDelay = FMC_SDRAM_RPIPE_DELAY_0;
/* SdramTiming */
SdramTiming.LoadToActiveDelay = 16;
SdramTiming.ExitSelfRefreshDelay = 16;
SdramTiming.SelfRefreshTime = 16;
SdramTiming.RowCycleDelay = 16;
SdramTiming.WriteRecoveryTime = 16;
SdramTiming.RPDelay = 16;
SdramTiming.RCDDelay = 16;

if (HAL_SDRAM_Init(&hsdram1, &SdramTiming) != HAL_OK)
{
Error_Handler( );
}

/* USER CODE BEGIN FMC_Init 2 */

/* USER CODE END FMC_Init 2 */
}

is there anything to configure please someone suggest how to configure SDRAM.

Hello @Pavankumar1_ 

According to the user manual, the U7 8M x 32bit SDRAM is connected to SDRAM Bank1 of the STM32H747XIH6 FMC interface.

Hello @Pavankumar1_ ,

Simply try to use BSP as reference: stm32h747i_discovery_sdram.c located under \Drivers\BSP\STM32H747I-DISCO in STM32CubeH7
