向LM3S615debug程序时需要将里边的原有程序擦除吗？debug上的程序出现cannot load from non-primitive location
#include "inc/hw_ints.h"
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "gpio.h"
#include "sysctl.h"
#define PINS GPIO_PIN_5

void delay(int d)
{
for(;d;--d);
}
//void SysCtlClockSet(unsigned long ulConfig)
//{}

//void SysCtlPeripheralEnable (unsigned long ulPeripheral)
//{}

//void GPIODirModeSet(unsigned long ulPort,unsigned char ucPins,unsigned long ulPinIO)
//{}

//void GPIOPinWrite(unsigned long ulPort, unsigned char ucPins, unsigned char ucVal)
//{}

int main(void)
{
unsigned int i;

   SysCtlClockSet(SYSCTL_SYSDIV_1|SYSCTL_USE_OSC|SYSCTL_OSC_MAIN|SYSCTL_XTAL_6MHZ);//直接使用外部晶振
   SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);//使能GPIO的PA模块
   GPIODirModeSet(GPIO_PORTA_BASE,PINS,GPIO_DIR_MODE_OUT);//设置PA5输出
   for(i=0;i<10;i++);
   {
   GPIOPinWrite(GPIO_PORTA_BASE,PINS,0x0);//置PA5低电平
   delay(20000);
   GPIOPinWrite(GPIO_PORTA_BASE,PINS,0x1);//置PA5高电平
   delay(20000);
   }
   SysCtlClockSet(SYSCTL_SYSDIV_1|SYSCTL_USE_PLL|SYSCTL_OSC_MAIN|SYSCTL_XTAL_6MHZ);//使用PLL
   for(i=0;i<10;i++)
   {GPIOPinWrite(GPIO_PORTA_BASE,PINS,PINS);
   delay(20000);
   GPIOPinWrite(GPIO_PORTA_BASE,PINS,PINS);
   delay(20000);
   }

   return 0;

}
