读写函数如下 u32 FSMC_NAND_WriteSmallPage(u8 *pBuffer, NAND_ADDRESS Address, u32 NumPageToWrite) {   u32 index = 0x00, numpagewritten = 0x00, addressstatus = NAND_VALID_ADDRESS;   u32 status = NAND_READY, size = 0x00;   while((NumPageToWrite != 0x00) && (addressstatus == NAND_VALID_ADDRESS) && (status == NAND_READY))   {     /* Page write command and address */     *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_PAGEPROGRAM;     *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;       *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0X00;       *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS);       *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS);            *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS);      /* Calculate the size */     size = NAND_PAGE_SIZE + (NAND_PAGE_SIZE * numpagewritten);     /* Write data */     for(; index < size; index++)     {       *(vu8 *)(Bank_NAND_ADDR | DATA_AREA) = pBuffer[index];     }          *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_PAGEPROGRAM_TRUE;     //    // while( GPIO_ReadInputDataBit(GPIOD, GPIO_Pin_6) == 0 );          /* Check status for successful operation */     status = FSMC_NAND_GetStatus();          if(status == NAND_READY)     {       numpagewritten++;       NumPageToWrite--;       /* Calculate Next small page Address */       addressstatus = FSMC_NAND_AddressIncrement(&Address);         }       }      return (status | addressstatus); } u32 FSMC_NAND_ReadSmallPage(u8 *pBuffer, NAND_ADDRESS Address, u32 NumPageToRead) {   u32 index = 0x00, numpageread = 0x00, addressstatus = NAND_VALID_ADDRESS;   u32 status = NAND_READY, size = 0x00;   while((NumPageToRead != 0x0) && (addressstatus == NAND_VALID_ADDRESS))   {                /* Page Read command and page address */     *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_READ_1;          *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;      *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0X00;      *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS);       *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS);       *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS);      *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_READ_TRUE;          //     //while( GPIO_ReadInputDataBit(GPIOD, GPIO_Pin_6) == 0 );          /* Calculate the size */     size = NAND_PAGE_SIZE + (NAND_PAGE_SIZE * numpageread);          /* Get Data into Buffer */         for(; index < size; index++)     {       pBuffer[index]= *(vu8 *)(Bank_NAND_ADDR | DATA_AREA);     }     numpageread++;          NumPageToRead--;     /* Calculate page address */                                         addressstatus = FSMC_NAND_AddressIncrement(&Address);   }   status = FSMC_NAND_GetStatus();      return (status | addressstatus); } 连续递增填充pBuffer函数： void Fill_Buffer(u8 *pBuffer, u16 BufferLenght, u32 Offset) {   u16 IndexTmp = 0;         for (IndexTmp = 0; IndexTmp < BufferLenght; IndexTmp++ )   {     pBuffer[IndexTmp] =IndexTmp+Offset ;   } 这样可以读写成功 但是当我修改连续填充函数后读写不成功，如： void Fill_Buffer(u8 *pBuffer, u16 BufferLenght, u32 Offset) {   u16 IndexTmp = 0;         for (IndexTmp = 0; IndexTmp < BufferLenght; IndexTmp++ )   {     pBuffer[IndexTmp] =2+Offset ;   } 现在输入都是2后读写不成功

读写函数如下
u32 FSMC_NAND_WriteSmallPage(u8 *pBuffer, NAND_ADDRESS Address, u32 NumPageToWrite)
{
  u32 index = 0x00, numpagewritten = 0x00, addressstatus = NAND_VALID_ADDRESS;
  u32 status = NAND_READY, size = 0x00;

  while((NumPageToWrite != 0x00) && (addressstatus == NAND_VALID_ADDRESS) && (status == NAND_READY))
  {
    /* Page write command and address */
    *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_PAGEPROGRAM;

    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00;  
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0X00;  
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS);  
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS);   
        *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS); 
    /* Calculate the size */
    size = NAND_PAGE_SIZE + (NAND_PAGE_SIZE * numpagewritten);

    /* Write data */
    for(; index < size; index++)
    {
      *(vu8 *)(Bank_NAND_ADDR | DATA_AREA) = pBuffer[index];
    }
    
    *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_PAGEPROGRAM_TRUE;

    //
   // while( GPIO_ReadInputDataBit(GPIOD, GPIO_Pin_6) == 0 );
    
    /* Check status for successful operation */
    status = FSMC_NAND_GetStatus();
    
    if(status == NAND_READY)
    {
      numpagewritten++;

      NumPageToWrite--;

      /* Calculate Next small page Address */
      addressstatus = FSMC_NAND_AddressIncrement(&Address);    
    }    
  }
  
  return (status | addressstatus);
}
u32 FSMC_NAND_ReadSmallPage(u8 *pBuffer, NAND_ADDRESS Address, u32 NumPageToRead)
{
  u32 index = 0x00, numpageread = 0x00, addressstatus = NAND_VALID_ADDRESS;
  u32 status = NAND_READY, size = 0x00;

  while((NumPageToRead != 0x0) && (addressstatus == NAND_VALID_ADDRESS))
  {           
    /* Page Read command and page address */
    *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_READ_1; 
   
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0x00; 
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = 0X00; 
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_1st_CYCLE(ROW_ADDRESS);  
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_2nd_CYCLE(ROW_ADDRESS);  
    *(vu8 *)(Bank_NAND_ADDR | ADDR_AREA) = ADDR_3rd_CYCLE(ROW_ADDRESS); 
    *(vu8 *)(Bank_NAND_ADDR | CMD_AREA) = NAND_CMD_READ_TRUE; 
   
    //
    //while( GPIO_ReadInputDataBit(GPIOD, GPIO_Pin_6) == 0 );
    
    /* Calculate the size */
    size = NAND_PAGE_SIZE + (NAND_PAGE_SIZE * numpageread);
    
    /* Get Data into Buffer */    
    for(; index < size; index++)
    {
      pBuffer[index]= *(vu8 *)(Bank_NAND_ADDR | DATA_AREA);
    }

    numpageread++;
    
    NumPageToRead--;

    /* Calculate page address */                                    
    addressstatus = FSMC_NAND_AddressIncrement(&Address);
  }

  status = FSMC_NAND_GetStatus();
  
  return (status | addressstatus);
}
连续递增填充pBuffer函数：
void Fill_Buffer(u8 *pBuffer, u16 BufferLenght, u32 Offset)
{
  u16 IndexTmp = 0;


  
  
  for (IndexTmp = 0; IndexTmp < BufferLenght; IndexTmp++ )
  {
    pBuffer[IndexTmp] =IndexTmp+Offset ;

  }
这样可以读写成功
但是当我修改连续填充函数后读写不成功，如：
void Fill_Buffer(u8 *pBuffer, u16 BufferLenght, u32 Offset)
{
  u16 IndexTmp = 0;


  
  
  for (IndexTmp = 0; IndexTmp < BufferLenght; IndexTmp++ )
  {
    pBuffer[IndexTmp] =2+Offset ;

  }
现在输入都是2后读写不成功
