TI中文支持网28035的ADC_SOC例程，在DEBUG调试下正常，可下载到FLASH后，点进行就会进到非法中断里面去
interrupt void ILLEGAL_ISR(VOID)
{
insert isr code here
next two lines for debug only to halt the processor here
remove after inserting isr code
asm(" ESTOPO);
for(;;);
}
请问一下如何解决这个问题

TI工程师们，怎么没人理我 ！是我说得不清楚？自己顶一下

您好，
请问有没有检查过所使用的 CMD 文件是否有问题？

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.
