DM8168中DSP如何储存数据在L2中



Hi~我在config_1G_256MLinux.bld文件中看到如下配置:

Build.platformTable["ti.platforms.evmTI816X:plat"]=

{

     ......

    ["DSP_L2_RAM",{

             comment:"DSP_L2_RAM",

             name:"DSP_L2_RAM",

             base:0x10800000,

             len:0x00020000

   }],

   l1PMode:"32K",

   l1DMode:"32K",

   l2Mode:"128K"

}

由此可以看出L2中256K的容量没有全部设为cache,有128K为RAM,如果我想将DSP核计算出来的数据存在L2的RAM中,再从L2中通过EDMA传输到DDR3中该如何做呢?
