Other Parts Discussed in Thread: TMS320C6678

您好！

      我在CCS v5中新建工程，然后将csl里自带的EDMA例子拷进去编译，结果出现了如下的16个错误，好像是同一个原因，请问是什么问题呢？谢谢！

errors encountered during linking; "edmatest_6678.out" not built

Linking failed. Check the Console window for details.

    您好，

    需要在properties->linker->file search path 中添加相应的csl lib库。

         您好！请问是添加\ccsv5\tools\compiler\c6000\lib 这个路径吗？如果是的话我已经添加了，可是还是出现上面这些问题，而且现在又多了以下的问题：This project was created using a version of Code Generation tools that is not currently installed: 7.2.1 [C6000]. Please install the Code Generation tools of this version, or migrate the project to one of the supported versions.请问是什么原因呢？我将工程文上传了，请您帮忙看一下是什么问题，非常感谢！

    您好，

    需要在include options中添加PDK_INSTALL_PATH\packages\ti\csl及PDK_INSTALL_PATH\packages；

    在file search path的include library file窗口中添加PDK_INSTALL_PATH\packages\ti\csl\lib\ti.csl.ae66

       您好！上面提到的问题用您给的方法解决了，非常感谢！现在编译没错误了，只是还有一个警告：Invalid project path: Duplicate path entries found (/edmatset_C6678 [Include path] isSystemInclude:true includePath:D:/TMS320C6678/CCS_5.0.3/CCSsetupfolder/ccsv5/tools/compiler/c6000/include), path: [/edmatset_C6678].请问这个警告对程序的运行有影响吗？谢谢！

    您好，

    请查看一下include path中是否有无效的路径，不会对程序运行产生影响。

             您好！上面与遇到的问题用您给的方法都解决了，现在编译已经没错误！非常感谢！接下来的问题就是在EVM板上进行仿真，我建好配置文件——launch——connect target——load program之后，在console里面显示如下信息C66xx_0: GEL Output: Setup_Memory_Map...

    C66xx_0: GEL Output: Setup_Memory_Map... Done.

    C66xx_0: GEL Output:

    Connecting Target...

    C66xx_0: GEL Output: DSP core #0

    C66xx_0: GEL Output: No initialization performed since bootmode = 0x00000005

    C66xx_0: GEL Output: You can manually initialize with GlobalDefaultSetup

    C66xx_0: GEL Output: Invalidate All Cache...

    C66xx_0: GEL Output: Invalidate All Cache... Done.

    C66xx_0: GEL Output: DSP Reset CPU...

    C66xx_0: GEL Output: DSP Reset CPU... Done.

    C66xx_0: GEL Output: Disable all EDMA3 interrupts and events.

    接下来要对EDMA功能进行测试应该怎么进行呢？我如何才能知道EDMA功能测试成功了呢？谢谢!

    您好，

    请先结合EDMA user guide及source code学习一下，然后再进行测试。
