Using C++ in TMS320 DSP....

Dear all:
         I've a problem about TMS320F2812 DSP using C++. I could run
my code correctly at the first time. When i pressed CCS "Debug->Rest
CPU",the code stuff at "new memory". what's wrong?? Could you help
me??

                                         Patrick Yu

int main()
{

    for(;;)
	{
		Initial();
		while(!CtrData->Reset)
		{	MainProcess();}
		End();
	}

}

void Initial(void)
{
	CtrData     = new CCtrSysData;  //Stuff when Reset CPU???
        ReadFifo    = new CFifo<U16>(300); //Stuff when Reset CPU???
	DecSendData = new CComData(3);
	CtrSendData = new CComData(1000);
	Decoder     = new CDecode(ReadFifo,DecSendData,CtrSendData,CtrData);
	CtrSys      = new CCtrSys(CtrData,CtrSendData);
	TimerTriger = new CTimerTriger;
	SendMsg     = new CSendMsg(DecSendData,CtrSendData);
	TimerTriger->DecodeTrgTime = DECODER_TRIG_RATE;
	CtrData->Reset = false;
	EINT;   // Enable Global interrupt INTM

}

void End(void)
{

  delete SendMsg;
  delete CtrSys;
  delete Decoder;
  delete CtrSendData;
  delete DecSendData;
  delete ReadFifo;
  delete CtrData;
  delete TimerTriger;
}

Are you running your code from RAM, internal or external, for testing?
If so, Debug->Reset CPU does not do the entire job.  It sets the
processor to pick up the start address from flash, not from your
downloaded image.

After the reset, do Debug->Restart.  This will set the processor to
start at the address specified in the image you loaded into RAM, not
at whatever is or is not in the flash.

Personally, I always use Debug->Reset CPU and then File->Reload
Program, since the reload only takes a few seconds.
