Hi, everyone,
I'm using F2812 and CCS3.3
I set the jumper to 'boot to flash' and tried to flash out the example project on to my dsp. Everything works fine.
My project can run in internal memory. In order to let it work in flash memory, i changed the memory map and added memcpy and initflash functions into my c code file.And in order to test my project, i configured the pwm outputs. But I got nothing. It seemed that my project didn't run at all. Why is this? What I did is just a little bit change of memory map.
This is my .c file.
...................................
InitPieVectTable();
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
InitFlash();
...................................
InitPWM();
for(i=0;i<6;i++)
PWM[i]=60;
SetPWMDIR(PWM,DIR);
The following is my .cmd file.

Thanks.
Any help is appreciated!
