TI中文支持网我的DSP程序运行DDR3，开始使用SPI boot，大部分上电是正常的，有时上电加载后程序出现出现异常，后来我用load的方式调试，发现了异常，打印信息如下：

从第二句开始是异常打印信息，这段打印是什么意思？什么情况下会出现这种打印？大家帮忙分析。
Andy Yin1：
提示出现内部异常，执行到非法代码段导致取指异常，应该是代码跑飞到数据段了，check一下是否跟DDR有关，将代码放在LL2是否有问题，还有check是否存在memory改写导致执行异常。

谢谢，我尽快在L2上试试看会不会有问题。

回复 Andy Yin1:
Andy,您好，我在移到L2试了一下，L2没有问题，可能还是DDR的问题；您还有其他联系方式么？方便的话给我邮箱发一下？我还有几个问题需要请教您一下，都比较急，在论坛上讨论有点麻烦，希望可以得到你的帮助，我的邮箱：416582723@qq.com
