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. Ini
tialize 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(;;)
{
}
}
