Other Parts Discussed in Thread: C2000WARE
我正在学习TMS320F280094，现在运行程序时（RAM与Flash都一样），只有在插着探针（XDS100V2）时才能正常运行，拔下后芯片就会停止运行（板子插着探针时，电流有0.09A，拔下后只有0.02A），重新插上后又能恢复正常运行，此时并没有进CCS的调试模式。
若断电后再上电，或者按下复位键，则需要重新烧录后才能正常工作。
选择的是运行方式选项来烧录。
已经配置为Flash模式（不过RAM模式的问题也一样），并添加宏定义
这是我的InitSysCtrl函数
void
InitSysCtrl(void)
{
//
// Disable the watchdog
//
DisableDog();
#ifdef _FLASH
//
// Copy time critical code and Flash setup code to RAM
// This includes the following functions: InitFlash();
// The RamfuncsLoadStart, RamfuncsLoadSize, and RamfuncsRunStart
// symbols are created by the linker. Refer to the device .cmd file.
//
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);
//
// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
//
InitFlash();
#endif
//
// PLLSYSCLK = (XTAL_OSC) * (IMULT + FMULT) / (PLLSYSCLKDIV)
//
InitSysPll(XTAL_OSC,IMULT_10,FMULT_0,PLLCLK_BY_2);
// InitSysPll(INT_OSC2,IMULT_10,FMULT_0,PLLCLK_BY_2);
#ifndef _FLASH
//
// Call Device_cal function when run using debugger
// This function is called as part of the Boot code. The function is called
// in the InitSysCtrl function since during debug time resets, the boot code
// will not be executed and the gel script will reinitialize all the
// registers and the calibrated values will be lost.
//
Device_cal();
#endif
//
// Turn on all peripherals
//
InitPeripheralClocks();
}这是我的main.c文件
//#include "System_Config.h"
#include "f28x_project.h"
#include "gpio.h"
#include "flash.h"
/**
* main.c
*/
void main(void)
{
// Flash_initModule(ctrlBase, eccBase, waitstates)
InitSysCtrl(); //系统初始化，配置时钟与看门狗，校准ADC与内部时钟
DELAY_US(30); //等待30us，保证3.3V电压轨已经稳定
InitGpio(); //初始化GPIO，将GPIO配置为默认状态，有点奇怪的是TI的示例都跳过的这一步
DINT; //禁用全局中断，开始初始化配置
InitPieCtrl(); //初始化PIE外设中断，配置为默认状态，即禁用所有外设中断，并清除中断标志位
IER = 0x0000; //禁用所有CPU中断
IFR = 0x0000; //清除所有CPU中断标志位
InitPieVectTable(); //初始化中断向量表，将所有中断服务程序（ISR）的入口地址设置为默认的空中断处理函数？（不太确定，反正是初始化为已知的值)
InitCpuTimers(); //初始化CPU定时器，记得在SysCtrl.c里面开时钟
GPIO_SetupPinMux(1, GPIO_MUX_CPU1, 0);
GPIO_SetupPinOptions(1, GPIO_OUTPUT, GPIO_PUSHPULL);
EINT; // 启用全局中断
ERTM; // 启用实时调试
while(1)
{
GPIO_togglePin(1);
DELAY_US(500000);
}
}
官方的C2000ware的文件我没有改动，编写了main.c函数

硬件方面，根据手册配置了BOOT引脚为闪存模式（两组排针均处于断路状态）
晶振方面，插着探针时用示波器测量，测得正常的20MHz正弦波，拔下探针后波形消失（此时探针与我的F280049板子并没有断电，若探针断电后再上电，即使插回我的板子仍然无法让芯片恢复正常工作）
