dontium 发表于 2014-3-28 11:37 是的。CMD文件就是联系具体地址的。
elvike 发表于 2014-3-28 12:50 那DSP281x_Headers_nonBIOS.cmd和烧录flash/ram的那个cmd ,这两者是什么关系呢
最多设置5个标签!

这一段是不是就是将寄存器变量对应到物理地址的啊?
那DSP281x_Headers_nonBIOS.cmd和烧录flash/ram的那个cmd ,这两者是什么关系呢
C281x的CPU没有玩过。不过,你看看手册上寄存器、存储器的分配,再看一下CMD文件,会弄清楚它的原理的。
这两个手册非常好。
在网上找的都是不全面的。
