在运行28035提供的例程 Example_2803xHRPWM_PrdUpDown_SFO_V6实验中
程序逐步执行没有问题,但是点击RUN之后再点Suspend,会再弹出一个页面有警告如下:
Can't find a source file at "C:\tidcs\c28\DSP2802x\INT3\DSP2802x_testing\SFO_v6_lib_build\source/SFO.c"Locate the file or edit the source lookup path to include its location.
请问这是什么问题?该如何解决。
Victor Zheng:
感觉象是编译的时候没有找对SFO.C的路径。看你的路径是2802x的
点击SFO.c 右键选择properties。重新选一下路径。在弹出的对话框中点Resouce 右边的loaction一栏重选路径。

回复 Victor Zheng:
是弹出的路径是2802x的,但是实际工程我用的是28035的,我在我的电脑里面都没有找到SFO.C这个文件,是不是另外需要装什么东西啊?

回复 Eric Ma:
我也遇到了同样的问题,不采用仿真的时候发现不了,一旦用仿真,按下暂停键就会提示如楼上的错误,有些工程有没有这个问题,请问需要做什么特殊设置嘛,我仿真的时候,发现程序无法正常往下执行了,卡在了PWM初始化这个地方了。

我按照原来的CLA工程进行一步步修改测试,发现当修改CMD文件的内存分配的时候,会出现这个错误:
Can't find a source file at "C:\tidcs\c28\DSP2802x\INT3\DSP2802x_testing\SFO_v6_lib_build
并且程序会停留在如下函数段。TI的工程师大神们,能帮忙解释下原因嘛,一旦出现后该如何修复,需要把CMD文件更改回去嘛,可能我添加了部分文件,原来的CMD文件已经不满足需求了,必须要更改CMD文件才能进行开发。// 查询MEP是否自动更新完成while(uiMEP == SFO_INCOMPLETE)// Call until complete{uiMEP = SFO();if(uiMEP == SFO_ERROR){error();// SFO function returns 2 if an error occurs & # of MEP steps/coarse step}// exceeds maximum of 255.}
附上CMD文件,帮忙分析下原因:

// by the CLA compiler for local symbols and temps
