TI中文支持网基于CCS6.2的平台上针对DSP2812进行的代码测试，关于ADC模块的初始化代码如下：
void F281X_ileg2_dcbus_drv_init(ILEG2DCBUSMEAS *p)
{
DELAY_US(ADC_usDELAY);
AdcRegs.ADCTRL1.all = ADC_RESET_FLAG;
asm(" NOP ");
asm(" NOP ");
AdcRegs.ADCTRL3.bit.ADCBGRFDN = 0x3;
DELAY_US(ADC_usDELAY);
AdcRegs.ADCTRL3.bit.ADCPWDN = 1;
AdcRegs.ADCTRL3.bit.ADCCLKPS = 6;
DELAY_US(ADC_usDELAY);
AdcRegs.ADCTRL1.all |= ADCTRL1_INIT_STATE;
AdcRegs.ADCTRL2.all |= ADCTRL2_INIT_STATE;
AdcRegs.ADCMAXCONV.bit.MAX_CONV1|= 0x0007;
AdcRegs.ADCCHSELSEQ1.all = p->ChSelect;
EvaRegs.GPTCONA.bit.T1TOADC = 1;
}
当屏蔽其中两条语句（AdcRegs.ADCTRL3.bit.ADCBGRFDN = 0x3;和AdcRegs.ADCTRL3.bit.ADCPWDN = 1;）时，程序可以正常的进行Debug调试（不过此时AD功能等于未启用）；当开通上述两条语句的时候不能正常进入EV定时中断（现象上中断中设置的用户计数器显示异常，为0或2989）;并且会在console界面中报出如下故障信息：
C28xx: Failed CPU Reset: (Error -1137 @ 0x6) Device is held in reset. Take the device out of reset, and retry the operation.

上述问题查了良久不得要领，请TI的工程师及各位江湖高手帮助分析，谢谢了。

首先给你个TI的例程你先对一下初始化代码有没不同的。其次，ADC启动导致芯片工作异常，你看看关中断行不行，查看ADC结果寄存器。还有电源没问题吧？

Eric，你好，谢谢你提供的例程；
基于你的例程，我通过CCS6.2进行导入。编译过程中更改如下配置界面：
到如下配置界面：
同时去掉C2000编译器中如下所示的路径设置：
全编译通过后下载到我的一块单板2812上（管脚基本都是悬空的，电源的稳定性今天因为在家里没法测试），编译没有错误，正常下载到DSP2812芯片上并且可以完成DSP的初始化过程，只是ADC的中断却一直没有进入，而且ConversionCount的数据也是0或者2989，如果在AD中断中打断点的话直接就跳出程序运行了，不知道怎么分析这个事情了？

补充一下，打了断点后程序跳出运行并报出错的信息如下：
