我是用的是TMS320F2808开发板，软件是CCS3.3，用的研旭的LED闪烁例程，直接下载到RAM里仿真是没问题的，然后按照教程替换cmd文件，烧写到Flash里，led就不闪烁了，只亮第一盏，不知道到底是什么问题，代码如下：
#include "DSP280x_Device.h" // DSP280x Headerfile Include File
#include "DSP280x_Examples.h" // DSP280x Examples Include File
// Select the example to compile in. Only one example should be set as 1
// the rest should be set as 0.
#define led1 GpioDataRegs.GPADAT.bit.GPIO0
#define led2 GpioDataRegs.GPADAT.bit.GPIO1
#define led3 GpioDataRegs.GPADAT.bit.GPIO2
#define led4 GpioDataRegs.GPADAT.bit.GPIO3
#define led5 GpioDataRegs.GPADAT.bit.GPIO4
#define led6 GpioDataRegs.GPADAT.bit.GPIO5
#define led7 GpioDataRegs.GPADAT.bit.GPIO6
#define led8 GpioDataRegs.GPADAT.bit.GPIO7
void Gpio_init(void);
void main(void)
{
// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP280x_SysCtrl.c file.
InitSysCtrl();
// Step 2. Initalize GPIO:
// This example function is found in the DSP280x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio(); Skipped for this example
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;
// Initialize 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 DSP280x_PieCtrl.c file.
InitPieCtrl();
// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in DSP280x_DefaultIsr.c.
// This function is found in DSP280x_PieVect.c.
InitPieVectTable();
Gpio_init();
// Step 4. Initialize all the Device Peripherals:
// This function is found in DSP280x_InitPeripherals.c
// InitPeripherals(); // Not required for this example
// Step 5. User specific code:
led1=1;
DELAY_US(500);
led2=1;
DELAY_US(500);
led3=1;
