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??

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.
