FSMC设置问题谁能帮我看一下程序急求谢谢

我的程序是这样的
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC,ENABLE);    打开时钟

void FSMC_Configuration(void)  //初始化
{

  FSMC_NORSRAMInitTypeDef  FSMC_NORSRAMInitStructure;

  FSMC_NORSRAMTimingInitTypeDef WriteTiming;
  FSMC_NORSRAMTimingInitTypeDef readWriteTiming;

  FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM4;//  ?aà??ò??ê1ó?NE4 ￡?ò2?í??ó|BTCR[6],[7]?￡
  FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable; // 2??′ó?êy?Yμ??·
  FSMC_NORSRAMInitStructure.FSMC_MemoryType =FSMC_MemoryType_SRAM;// FSMC_MemoryType_SRAM;  //SRAM
  FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;//′?′￠?÷êy?Y?í?è?a16bit
  FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode =FSMC_BurstAccessMode_Disable;// FSMC_BurstAccessMode_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;
  FSMC_NORSRAMInitStructure.FSMC_AsynchronousWait=FSMC_AsynchronousWait_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WrapMode = FSMC_WrapMode_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;
  FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable; //  ′?′￠?÷D′ê1?ü
  FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable; // ?áD′ê1ó?2?í?μ?ê±Dò
  FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &readWriteTiming; //?áD′ê±Dò
  FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &WriteTiming;  //D′ê±Dò

  WriteTiming.FSMC_AddressSetupTime = 15;    //μ??·?¨á￠ê±??￡¨ADDSET￡??a1??HCLK
  WriteTiming.FSMC_AddressHoldTime = 15;    //μ??·±￡3?ê±??￡¨A
  WriteTiming.FSMC_DataSetupTime = 255;    ////êy?Y±￡′?ê±???a4??HCLK
  WriteTiming.FSMC_BusTurnAroundDuration= 15;
  WriteTiming.FSMC_CLKDivision =16;
  WriteTiming.FSMC_DataLatency = 17;
  WriteTiming.FSMC_AccessMode = FSMC_AccessMode_A;    //?￡ê?A

  FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);  //3?ê??ˉFSMC????

  FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM4, ENABLE);  // ê1?üBANK1

}

我目的是让 FSMC_D1位置1
#define Bank1_SRAM4_ADDR ((uint32_t)(0x6C000000))
#define GSM_POWER_ON FSMC_SRAM_WriteBuffer((uint32_t *)Bank1_SRAM4_ADDR,(uint16_t *)0x0002,1)
#define GSM_POWER_OFF FSMC_SRAM_WriteBuffer((uint32_t *)Bank1_SRAM4_ADDR,(uint16_t *)0x0000,1)

void FSMC_SRAM_WriteBuffer( uint32_t *pAddress,uint16_t* pBuffer,uint32_t n)
{
for(;n!=0;n--)
  {
   *(uint16_t*)(pAddress)=*pBuffer;
   pAddress++;
   pBuffer++;
}
}

这是所有的初始化和用到的函数，但是FSMC_D1不能够输出高电平不知道哪里设置有问题，或者遗漏什么了，请大神指教
