请问TMS28035 ADC例程下载到FLASH出错

cmd文件是官方的，我没有改过，程序单步运行到下面的这句后就进非法中断了 DELAY_US(ADC_usDELAY);         // Delay before converting ADC channels }

void InitAdc(void) {     extern void DSP28x_usDelay(Uint32 Count);

    // *IMPORTANT*     // The Device_cal function, which copies the ADC calibration values from TI reserved     // OTP into the ADCREFSEL and ADCOFFTRIM registers, occurs automatically in the     // Boot ROM. If the boot ROM code is bypassed during the debug process, the     // following function MUST be called for the ADC to function according     // to specification. The clocks to the ADC MUST be enabled before calling this     // function.     // See the device data manual and/or the ADC Reference     // Manual for more information.

        EALLOW;         SysCtrlRegs.PCLKCR0.bit.ADCENCLK = 1;         (*Device_cal)();         EDIS;

    // To powerup the ADC the ADCENCLK bit should be set first to enable     // clocks, followed by powering up the bandgap, reference circuitry, and ADC core.     // Before the first conversion is performed a 5ms delay must be observed     // after power up to give all analog circuits time to power up and settle

    // Please note that for the delay function below to operate correctly the     // CPU_RATE define statement in the DSP2803x_Examples.h file must     // contain the correct CPU clock period in nanoseconds.     EALLOW;     AdcRegs.ADCCTL1.bit.ADCBGPWD  = 1;      // Power ADC BG     AdcRegs.ADCCTL1.bit.ADCREFPWD = 1;      // Power reference     AdcRegs.ADCCTL1.bit.ADCPWDN   = 1;      // Power ADC     AdcRegs.ADCCTL1.bit.ADCENABLE = 1;      // Enable ADC     AdcRegs.ADCCTL1.bit.ADCREFSEL = 0;      // Select interal BG     EDIS;
