使用FSMC来刷新LCD，在使用bank1.sector4已经能成功刷屏，想要修改为使用bank1.sector1，修改下面的地方却不能实现刷屏，麻烦帮忙看看是有那里没设置好。
typedef struct{
    u16 CMD;
    u16 DATA;
}LCDType;

#define    AHDDR_BASE    (u32)(0x60000000)        //#define    AHDDR_BASE    (u32)(0x6C000000)
#define    LCD          ((LCDType *)(AHDDR_BASE | ((0x01 << 11) - 2)))


static void LCD_FSMCInit(void)
{
    FSMC_NORSRAMInitTypeDef FSMC_NORSRAMInitStruct;
    FSMC_NORSRAMTimingInitTypeDef FSMC_ReadWriteTimingStruct;

    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);
   
    FSMC_ReadWriteTimingStruct.FSMC_AddressHoldTime = 0x00;               
    FSMC_ReadWriteTimingStruct.FSMC_AddressSetupTime = 0x01;               
    FSMC_ReadWriteTimingStruct.FSMC_BusTurnAroundDuration = 0x00;            
    FSMC_ReadWriteTimingStruct.FSMC_CLKDivision = 0x00;                    
    FSMC_ReadWriteTimingStruct.FSMC_DataLatency = 0x00;                    
    FSMC_ReadWriteTimingStruct.FSMC_DataSetupTime = 0x01;   
    FSMC_ReadWriteTimingStruct.FSMC_AccessMode = FSMC_AccessMode_B;
   
    FSMC_NORSRAMInitStruct.FSMC_Bank = FSMC_Bank1_NORSRAM1;   //FSMC_NORSRAMInitStruct.FSMC_Bank = FSMC_Bank1_NORSRAM4;
    FSMC_NORSRAMInitStruct.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable;
    FSMC_NORSRAMInitStruct.FSMC_ExtendedMode = FSMC_ExtendedMode_Enable;
    FSMC_NORSRAMInitStruct.FSMC_WriteOperation = FSMC_WriteOperation_Enable;
    FSMC_NORSRAMInitStruct.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;
    FSMC_NORSRAMInitStruct.FSMC_MemoryType = FSMC_MemoryType_SRAM;
    FSMC_NORSRAMInitStruct.FSMC_ReadWriteTimingStruct = &FSMC_ReadWriteTimingStruct;
    FSMC_NORSRAMInitStruct.FSMC_WriteTimingStruct = &FSMC_ReadWriteTimingStruct;
    FSMC_NORSRAMInit(&FSMC_NORSRAMInitStruct);
    FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM1,ENABLE);     //FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM4,ENABLE);
}

PS：注释部分是原来使用bank1.sector4可以实现刷屏的，红 {MOD}部分是打算使用bank1.sector1而做出的修改，但改修改不能刷屏成功。
麻烦各位大神指点一下是哪里没修改好从而导致使用bank1.sector1刷屏失败。
