关于CMD文件

Bruce
Expert 2070 points


是不是每建立一个DSP工程，都要新建一个CMD文件？

   我自己建立了一个工程28335文件，复制官方实例文件中的CMD文件，官方文件夹中给的CMD文件很多，具体怎么使用啊？比如说官方实例文件夹中的：

28335_RAM_lnk.cmd

F28335.cmd

DSP2833x_Headers_BIOS.cmd

DSP2833x_Headers_nonBIOS.cmd

    如果您只是烧写到RAM中仿真，掉电就丢失：

    1) 28335_RAM_lnk.cmd

    2) DSP2833x_Headers_nonBIOS.cmd

    如果你要烧写到Flash中，掉电不丢失：

    1) F28335.cmd

    2) DSP2833x_Headers_nonBIOS.cmd

    前两者都是针对无BIOS的情况，这也是一般的情况。 如果用到BIOS，另当别论。

    可是我复制DSP2833x_Headers_nonBIOS.cmd到我的工程，也包含了其他一些头文件，老是遇到一些错误和报警，比如：

    建议楼主用TI的历程，在历程上修改。

    关键我还是不明白这些错误在哪里，在TI 的例程中都可以通用，建个工程就不能用，有点搞蒙了

    您要跟TI历程一个一个文件比较，到底少添加了哪个文件。

    最好的办法就是直接在TI的历程上修改，复制一个历程，在相同文件夹下改个名字即可。
