CCS9.2.0新建28335的程序下载到RAM中可以正常运行，当程序下载到FLASH中程序无法正常运行，暂停后发现程序一直在如下FLASH搬运到RAM的程序中运行；
void MemCopy(Uint16 *SourceAddr, Uint16* SourceEndAddr, Uint16* DestAddr)
{
while(SourceAddr < SourceEndAddr)
{
*DestAddr++ = *SourceAddr++;
}
return;
}
该程序在CCS6中建工程也会出现类似的问题，即在RAM中可正常运行，而在FLASH中可能运行有误，但在CCS6中通过调整properties->optimization中speed的大小有时可以正常运行FLASH的程序。
该问题一直没能得到解决，希望各位大神能指点迷津，万分感谢！！！
如下为FLASH部分的程序：
#define FLASH
#ifdef FLASH
#pragma CODE_SECTION(MainISR,"ramfuncs");
#pragma CODE_SECTION(OffsetISR,"ramfuncs");
//#pragma CODE_SECTION(FreeISR,"ramfuncs");
#endif
extern Uint16 *RamfuncsLoadStart, *RamfuncsLoadEnd, *RamfuncsRunStart;
#ifdef FLASH
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
InitFlash();
#endif //(FLASH)
如下为FLASH部分CMD文件的分配：
