Problem reading or writing to NAND Flash with FSMC

Hello All,

I am working on STM32F407ZGT6 and HY27UF081G2A NAND Flash. You can find schematics and data sheets in the attached file. I am using CubeMX to generate codes on Keil U5. You can find initialization codes below.

/** Perform the NAND1 memory initialization sequence*/

hnand1.Instance = FSMC_NAND_DEVICE;

/* hnand1.Init */

hnand1.Init.NandBank = FSMC_NAND_BANK2;

hnand1.Init.Waitfeature = FSMC_NAND_PCC_WAIT_FEATURE_ENABLE;

hnand1.Init.MemoryDataWidth = FSMC_NAND_PCC_MEM_BUS_WIDTH_8;

hnand1.Init.EccComputation = FSMC_NAND_ECC_DISABLE;

hnand1.Init.ECCPageSize = FSMC_NAND_ECC_PAGE_SIZE_512BYTE;

hnand1.Init.TCLRSetupTime = 0x2;

hnand1.Init.TARSetupTime = 0x2;

/* hnand1.Info */

hnand1.Info.PageSize = 0x00000800; // 2048 Bytes/Page

hnand1.Info.SpareAreaSize = 0x00000040; // 64 Bytes Spare

hnand1.Info.BlockSize = 0x00000040; // 64 Pages/Block

hnand1.Info.BlockNbr = 0x00000400; // 1024 Blocks

hnand1.Info.ZoneSize = 0x00000400; // 1024 Blocks/Zone

/* ComSpaceTiming */

ComSpaceTiming.SetupTime = 0x5;

ComSpaceTiming.WaitSetupTime = 0x3;

ComSpaceTiming.HoldSetupTime = 0x2;

ComSpaceTiming.HiZSetupTime = 0x5;

/* AttSpaceTiming */

AttSpaceTiming.SetupTime = 0x5; //0;

AttSpaceTiming.WaitSetupTime = 0x3; //2;

AttSpaceTiming.HoldSetupTime = 0x2; //1;

AttSpaceTiming.HiZSetupTime = 0x5; //4;

if (HAL_NAND_Init(&hnand1, &ComSpaceTiming, &AttSpaceTiming) != HAL_OK)

{

Error_Handler();

}

When I try to readID (HAL_NAND_Read_ID) it looks like the CPU is stuck. It doesn't go further after the first line of the command sequence. 

/* Send Read ID command sequence */

*(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA)) = NAND_CMD_READID;

(it looks like it is in an infinite loop here)

*(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U;

I would appreciate it if someone help me with the issue.

Regards.

hnand1.Init.Waitfeature = FSMC_NAND_PCC_WAIT_FEATURE_ENABLE;

to 

hnand1.Init.Waitfeature = FSMC_NAND_PCC_WAIT_FEATURE_DISABLE;

solved the problem

Hi Tugrul Matras, 

I am new to ST and am using the same config to read the Nand flash. Did your profiled on how quickly you can read from the flash. I see that the reads using processor are extremely slow. 

Thanks, 

AQ

Hi

Regarding

Matras.Tugrul

'spost, you can change the value of

hnand1.Init.Waitfeature in the pinout view/FSMC/Nand Flash1/ Ready or busy (I am working on the lastest CubeMX release 4.24) :

it will automatically generate the following code :
