28035 CPU中断与CLA中断冲突？

Other Parts Discussed in Thread: TMS320F28035

大家好！我现在用TMS320F28035做一个电源的控制，其中CLA处理闭环程序，由ADC触发，ADC采样由EPWM触发，这些调试中都没问题。现在想加一个Timer0的1kHz中断用来做定时，但是调试中发现使能PieCtrlRegs.PIEIER1.bit.INTx7 = 1之后（下面程序中标***部分），程序一运行就停止，且显示“No source available for "0x3ff599" ”，再运行还是马上停止显示同样的内容，我查了一下0x3ff599是属于Boot ROM。如果把使能中断那一行屏蔽掉，则运行正常（不产生Timer0中断）。我试过其他的中断，比如让CPU处理一个ADC中断，也会发生同样的问题。请问这是什么原因呢？

main()的内容为：

DeviceInit(); // Device Life support & GPIO

memcpy((Uint16 *)&RamfuncsRunStart,(Uint16 *)&RamfuncsLoadStart, (unsigned long)&RamfuncsLoadSize);

InitFlash();

CLA_Init();

InitEPwmGpio();

InitCpuTimers();

ConfigCpuTimer(&CpuTimer0, 60, 50000);

CpuTimer0Regs.PRD.all = mSec0_5;

EPWM_CNF();

DPL_CLAInit(); // Digital Power (DP) library initialization

// INTERRUPT & ISR INITIALISATION

PieVectTable.TINT0 = &TimerIsr0; // 1 KHz ISR from CPU Timer 2

PieVectTable.EPWM1_TZINT = &EpwmTZ1;

EALLOW;

PieCtrlRegs.PIEIER1.bit.INTx7 = 1; // PIE level enable, Grp1 / Int7 TINT0*******************

PieCtrlRegs.PIEIER2.bit.INTx1 = 1; // PIE level enable, Grp2 / Int1 EPWM1_TZINT

EDIS;

IER |= M_INT1|M_INT2; // Enable CPU INT1&2 connected to EPWM1-6 INTs:

EINT; // Enable Global interrupt INTM

ERTM; // Enable Global realtime interrupt DBGM

// Background Loop
for (;;);

Timer0中断处理程序为：

#pragma CODE_SECTION(TimerIsr0,"ramfuncs");
__interrupt void TimerIsr0(void) // 2kHz
{
Counter_500us++;
if (Counter_500us > 9)
Counter_5ms++;

PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
}

考虑一下PIE有没有正确初始化？

谢谢您的回复。应该不是PIE的配置问题，因为我把CLA相关的程序注释掉后，Timer0的中断就很正常。请问还可能是什么原因呢？
