2812的外扩RAM问题



网友abc123在21ic TI DSP技术论坛问以下问题未能解决:

现在遇到一个问题,就是外扩RAM初始化的问题,我的板子是外扩区6
   ZONE6ipcb  : origin = 0x100000, length = 0x001FFF
   ZONE6mag   : origin = 0x102000, length = 0x001FFF
   ZONE6tf    : origin = 0x104000, length = 0x001FFF
   FFTipcb  ALIGN(2048) :{} > ZONE6ipcb  PAGE = 1
   FFTmag               : > ZONE6mag     PAGE = 1
   FFTtf                : > ZONE6tf      PAGE = 1
  这个是我在cmd文件中的写的,不知道有没有错误,还有就是初始化怎么弄,怎么选中6区
