为什么c5416不能访问外部flash？我要烧写程序到外部flash，如下程序运行时出错

void main()
{
BYTE *FlashPtr;
int i;
int FlashData=0xAAAA;

FlashPtr=(BYTE *)0x8000;
while(1)
{
//WriteFlash(FlashPtr,FlashData);
i=*FlashPtr; //去掉这句就没问题

printf("%X\n",i);
}

错误如下

Error 0x80000020/-1058
Fatal Error during:Execution,
Device driver: Emulator Controller not responding
It is recommended to RESET EMULATOR . This will disconnect each target from the emulator. .
