C2000 运行就进入RTOSINT_ISR中断 [复制链接]

下载到flash后 仿真界面上点运行，就进入RTOSINT_ISR中断了，而直接下载到内存中不会出现这种情况。这是怎么回事？？？？
用的TMS320F28031      XDS100 v2   
请大神指教

elvike

把文件列表晒出来，可能是没有nonBIOS文件，或者是没有codestart那个文件。反正是flash启动的文件不全。应该是缺少nonBIOS文件，因为你进入的是RTOS中断，这个是实时操作系统中断

anananjjj

相关的CMD 配置不对吧？

dontium

没烧好。CMD分配不正确。

至少来个工程截图，便于分析。什么都没有，大家只能想当然的猜了

我添加了这些文件、


我试了一下。官方的LED闪烁工程  main.c  一切正常。自己改的教程就不能在下载到FLASH是正常工作。

官方的例程：
#include "DSP28x_Project.h"     // Device Headerfile and Examples Include File

// Prototype statements for functions found within this file.
interrupt void cpu_timer0_isr(void);

void main(void)
{

// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP2803x_SysCtrl.c file.
   InitSysCtrl();

// Step 2. Initalize GPIO:
// This example function is found in the DSP2803x_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 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 DSP2803x_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 DSP2803x_DefaultIsr.c.
// This function is found in DSP2803x_PieVect.c.
   InitPieVectTable();

// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.
   EALLOW;  // This is needed to write to EALLOW protected registers
   PieVectTable.TINT0 = &cpu_timer0_isr;
   EDIS;    // This is needed to disable write to EALLOW protected registers

// Step 4. Initialize the Device Peripheral. This function can be
//         found in DSP2803x_CpuTimers.c
   InitCpuTimers();   // For this example, only initialize the Cpu Timers
// Configure CPU-Timer 0 to interrupt every 500 milliseconds:
// 60MHz CPU Freq, 50 millisecond Period (in uSeconds)
   ConfigCpuTimer(&CpuTimer0, 60, 500000);


// To ensure precise timing, use write-only instructions to write to the entire register. Therefore, if any
// of the configuration bits are changed in ConfigCpuTimer and InitCpuTimers (in DSP2803x_CpuTimers.h), the
// below settings must also be updated.

   CpuTimer0Regs.TCR.all = 0x4001; // Use write-only instruction to set TSS bit = 0

// Step 5. User specific code, enable interrupts:

// Configure GPIO34 as a GPIO output pin
   EALLOW;
   GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;
   GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;
   EDIS;

// Enable CPU INT1 which is connected to CPU-Timer 0:
   IER |= M_INT1;

// Enable TINT0 in the PIE: Group 1 interrupt 7
   PieCtrlRegs.PIEIER1.bit.INTx7 = 1;

// Enable global Interrupts and higher priority real-time debug events:
   EINT;   // Enable Global interrupt INTM
   ERTM;   // Enable Global realtime interrupt DBGM

// Step 6. IDLE loop. Just sit and loop forever (optional):
   for(;;);
}


interrupt void cpu_timer0_isr(void)
{
   CpuTimer0.InterruptCount++;
   GpioDataRegs.GPBTOGGLE.bit.GPIO34 = 1; // Toggle GPIO34 once per 500 milliseconds
   // Acknowledge this interrupt to receive more interrupts from group 1
   PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
}
