程序一旦执行到这一句就会进入死循环，而事实上这个地址不存在，C盘下根本没有ti文件夹。怎么解决？
自己的程序是这样的，应该是作除法时出了问题。
您现在controlSUITE没有安装在默认位置？在我的电脑默认安装路径下可以找到
C:\ti\controlSUITE\libs\math\FPUfastRTS\V100\source

我是没有安装在默认位置，一定要这样做是吗？
我已经重新安装了controlSUITE在默认路径下，可是代码还是会死在0x338490~0x338495这个死循环内。
而且通常在调用函数时会出现这个问题。
DTPMSM.zip
我试了一下，并没有死循环。您现在的死循环是指什么？
我在p->Ek = p->Give- p->Feedback; 打断点，而后向下运行，之后会到main.c文件的 A_Isq1_R.Give = currentref;
有时候也不是在这个地方，就是程序在连续运行时，暂停一下，会发现进入了死循环，您有这个问题吗？
