我的2812 DSP程序大体是这样的：
1、用SCIB中断接收485数据，接收完后发送一组数据，中断接收周期为200ms；
2、我的中断接收的程序如下，因为这部分涉及到一个数据的转义（一包数据中遇到0x10会转移成0x10 0x10（不包括帧头帧尾及校验），接收到这包数后，要正确解析），之前没有转义的时候，程序一点问题都没有，可能是这段程序不知道哪里出了问题，查了半天也没查到。
3、前两天程序跑个三、四个小时就进非法中断（连仿真器）；从昨天晚上开始跑，跑到今天早晨，一共跑了十几个小时，又死了，但是这次提示一个错误（如附件），貌似是什么堆栈溢出之类的，查了一天也没找到根源，现在急的要命要命的，希望论坛里的朋友能帮忙支支招。
