Susan Yang：

请您私信/上传完整工程，我们来测试一下，谢谢

回复 Susan Yang:

我单步运行发现本应该顺序执行的程序它会自己陷入循环，很奇怪

Susan Yang：

回复 xiaomemg:

我这边是可以的。请问能具体说一下您是在那个语句会自己进入循环？

xiaomemg：

回复 Susan Yang:

UINT16 CiA402_Init(void)里面的HMEMSET(&LocalAxes[AxisCnt],0,SIZEOF(TCiA402Axis));
你加个断点会发现这个地方会执行好多次 按照程序应该是两次才对

LocalAxes[AxisCnt].ObjDic = (TOBJECT *) ALLOCMEM(SIZEOF(DefCiA402AxisObjDic));
HMEMCPY(LocalAxes[AxisCnt].ObjDic,&DefCiA402AxisObjDic,SIZEOF(DefCiA402AxisObjDic));
在这两句分别加断点 你会发现会在这两个不断循环

Susan Yang：

回复 xiaomemg:

1 在您给出的工程中，下面的语句是被注释的

//HMEMSET(&LocalAxes[AxisCnt],0,SIZEOF(TCiA402Axis));

2 这一句也是注释的

// CiA402_Init();

请问您是参考哪个路径下的TI例程修改的？使用的是TI开发板（型号是什么）？

回复 Susan Yang:

在注释的后面有跟这个一样的函数开发板是28379d
