我编写了一个程序，原来都在RAM里面跑都正常，后来程序大了，就想烧写到FLASH里面进行调试，不过无论怎么修改，当烧写成功后，重新上电都没法启动，不知道是什么原因，而且当烧写完之后，如果不下电，只是把仿真器拔掉是可以正常运行的。不知大家是否有遇到过这种问题？是不是只是在RAM里面运行，而程序没把代码烧写到FLASH里面？或者没调用？
附上CMD代码：

主程序为：
void main(void)
{
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
InitFlash();
DINT;
InitSysCtrl(); //系统初始化

InitGpio(); //IO初始化

IFR = 0x0000;
InitPieVectTable();//外部中断初始化
InitCpuTimers(); //CPU时钟初始化
InitAdc(); //init the ADC
InitSci(); //SCI通信初始化
