28335，仿真器是100v3，做EXRAM写入外部SRAM实验提示上图错误，折磨我两天了，试过打开cl2000.exe，试过修改主函数为最简单的写入函数，试过降低写入值，都没能解决，求大神帮帮我这个新手！
下面是主函数：
#include "DSP2833x_Device.h"    // DSP2833x HeadeRFile Include File
#include "DSP2833x_Examples.h" // DSP2833x Examples Include File

Uint16 *ExRamstart = (Uint16 *)0x180000;

void main(void)
{
Uint16       i;
// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral clocks
// This example function is found in the DSP2833x_SysCtrl.c file.
InitSysCtrl();

// Step 2. Initalize GPIO:
// This example function is found in the DSP2833x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio();  // Skipped for this example
InitXintf16Gpio();       //zq

// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;

// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabLED and flags
// are cleared.
// This function is found in the DSP2833x_PieCtrl.c file.
InitPieCtrl();

// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;

// Step 4. Write Data to SRAM:

      for(i = 0; i < 0xFFFF; i++)
      {
            *(ExRamStart + i) = 0x5555;
            if(*(ExRamStart + i) != 0x5555)
            {
                     while(1);
            }
      }

      for(i = 0; i < 0xFFFF; i++)
      {
            *(ExRamStart + i) = 0xAAAA;
            if(*(ExRamStart + i) != 0xAAAA)
            {
                     while(1);
            }
      }

      for(i = 0; i< 0xFFFF; i++)
      {
            *(ExRamStart + i) = i;
            if(*(ExRamStart + i) != i)
            {
                     while(1);
            }
            if(*ExRamStart == 0x4000)
               {
         while(1);
               }
      }
i=0;
for(;;)
{

}

}
