STM32写华邦w25X16时读正确，却写不进去，用自己的程序可以读出例程写进去的的字符串，但是自己的程序写不进去内容
/*要写入到W25X16的字符串数组*/
const u8 TEXT_Buffer[]={"神州三号 SPI 读写访问程序"};
#define SIZE sizeof(TEXT_Buffer)

SPI_FLASH_Write_Page(chars,100,SIZE);

/*
SPI在一页内写入数据
NumByte:要写入的字节数（《256），不超过该页的剩余字节数
*/
void SPI_FLASH_Write_Page(u8 *pBuffer, u32 WriteAddr,u16 NumByte)
{
                u16 i = 0;
                SPI_FLASH_Write_Enable();
                SPI_FLASH_CS_Low();
       
                SPI_ReadWriteByte(W25X_PageProgram);//发送写页命令
       
                SPI_ReadWriteByte((u8)((WriteAddr)>>16));//24位地址
                SPI_ReadWriteByte((u8)((WriteAddr)>>8));//
                SPI_ReadWriteByte((u8)(WriteAddr));//
       
                for( i= 0;i < NumByte;i++)
                SPI_ReadWriteByte(pBuffer);//
       
                SPI_FLASH_CS_High();
                SPI_FLASH_Wait_Busy();
}

为什么会写不进去

/*
SPI读写
*/
u8 SPI_ReadWriteByte(u8 TxData)
{

  while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);

  /* Send byte through the SPI1 peripheral */
  SPI_I2S_SendData(SPI1, TxData);

  /* Wait to receive a byte */
  while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);

  /* Return the byte read from the SPI bus */
  return SPI_I2S_ReceiveData(SPI1);
