28377D 中AD采样的奇怪问题-TI中文支持网

我在调试28377D的过程中遇到了奇怪的问题，描述如下：

1。ADC正常配置，使用了ABCD四路AD，在自制控制板（未接底板）时正常采样，且调试时刷新正常；但接上底板后，采样不正常，A通道有两个数值闪烁，其他通道多数值不变（已经测量控制板上AD的参考电压，各通道输入电压正常）。

2。上述情况中，A通道的采样结果仍然对不上。以上均由CPU1完成；CPU2基本无内容，仅初始化。但问题来了，偶然间发现，CPU1正常运行中，将CPU2编译烧写程序后载入，虽然会有Error setting the GSxMSEL register for Flash operations的错误，但是此时CPU1暂停并继续后，AD采样的数值就都正常了！！但另外一个问题，此时跑马灯闪烁的频率明显比原来小了十几倍。

求救啊，能否明示一下哪里有问题。
