你好,请问cmd文件table(_prginRAM)的含义及用法,谢谢。
是我司产品上的一个文件,完整的配置文件如下。标红色部分的 table(_prginRAM)不知道是啥意思?大概功能是在InitFlash之前把flash中的部分程序复制到RAM中。
主程序初始化部分包含下面两个子程序:
copy_prg (&prginRAM); // Move the program from FLASH to RAM
InitFlash (); // Initializes the Flash Control registers

是的,ramfuncs这个分区确实是用来将flash部分的程序复制到ram运行的,但是table()确实没有看到过,我搜索到的资料也是显示这个函数是用在数据库中的,没在CCS工程中找到这个函数的定义
