STM32F469 FMC NANDFLASH读取ID故障

dengzh2367

使用F469操作nandflash（16bit）时，在读取ID时，执行读命令时，出现如下图片故障。使用cubemx生成nandflash代码和更改F407代码都不行，都出现图片故障。


读取ID代码如下；
  /* Send Read ID command sequence */   
  *(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA))  = NAND_CMD_READID;
  *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U;

  /* Read the electronic signature from NAND flash */  
  data = *(__IO uint32_t *)deviceaddress;

  /* Return the data read */
  pNAND_ID->Maker_Id   = ADDR_1ST_CYCLE(data);
  pNAND_ID->Device_Id  = ADDR_2ND_CYCLE(data);
  pNAND_ID->Third_Id   = ADDR_3RD_CYCLE(data);
  pNAND_ID->Fourth_Id  = ADDR_4TH_CYCLE(data);

初始化代码如下：
  FMC_NAND_PCC_TimingTypeDef ComSpaceTiming;
  FMC_NAND_PCC_TimingTypeDef AttSpaceTiming;

  /** Perform the NAND1 memory initialization sequence
  */
  hnand1.Instance = FMC_NAND_DEVICE;
  /* hnand1.Init */
  hnand1.Init.NandBank = FMC_NAND_BANK3;
  hnand1.Init.Waitfeature = FMC_NAND_WAIT_FEATURE_ENABLE;
  hnand1.Init.MemoryDataWidth = FMC_NAND_MEM_BUS_WIDTH_16;
  hnand1.Init.EccComputation = FMC_NAND_ECC_DISABLE;
  hnand1.Init.ECCPageSize = FMC_NAND_ECC_PAGE_SIZE_256BYTE;
  hnand1.Init.TCLRSetupTime = 0;
  hnand1.Init.TARSetupTime = 0;
       


        /* hnand1.Info */
  hnand1.Info.PageSize = NAND_PAGE_SIZE;
  hnand1.Info.SpareAreaSize = NAND_SPARE_AREA_SIZE;
  hnand1.Info.BlockSize = NAND_BLOCK_SIZE;
  hnand1.Info.BlockNbr = NAND_MAX_ZONE;
  hnand1.Info.ZoneSize = NAND_ZONE_SIZE;
  /* ComSpaceTiming */
  ComSpaceTiming.SetupTime = 1;
  ComSpaceTiming.WaitSetupTime = 3;
  ComSpaceTiming.HoldSetupTime = 2;
  ComSpaceTiming.HiZSetupTime = 1;
  /* AttSpaceTiming */
  AttSpaceTiming.SetupTime = 1;
  AttSpaceTiming.WaitSetupTime = 3;
  AttSpaceTiming.HoldSetupTime = 2;
  AttSpaceTiming.HiZSetupTime = 1;

  if (HAL_NAND_Init(&hnand1, &ComSpaceTiming, &AttSpaceTiming) != HAL_OK)
  {
    Error_Handler();
  }

GPIO初始化：
/* Peripheral clock enable */
  __HAL_RCC_FMC_CLK_ENABLE();

各位大神，帮帮看看，已经纠结我两天了，接近崩溃了，先谢了！

大神们帮忙看看，重金回报！

正点原子

参考下我们的例程吧

Joofee_Elec

[mw_shl_code=c,true]hnand1.Init.Waitfeature = FMC_NAND_WAIT_FEATURE_ENABLE;[/mw_shl_code]
修改为
[mw_shl_code=c,true]hnand1.Init.Waitfeature = FMC_NAND_WAIT_FEATURE_DISABLE;[/mw_shl_code]

下午调试时发现不是wait的原因，。
建立项目的时候将FMC全部配置为Pull up。
