2810在线仿真和flash操作

我用的DSP2810，在线仿真时需要调用CMD文件，手头上只有对应2812的cmd文件F2812_EzDSP_RAM_lnk.cmd，请问哪里可以下到2810的。如果我自己从2812的cmd上改需要怎么怎么做？另外，我的产品最终在运行时，需要在运行过程中将一些参数存储到片上FLASH里，防止掉电时丢失，要怎么操作？没找到例程。

Ke li2,

不推荐你自己改

你可以到TI官网以下链接下载例程包，“C281x C/C++ Header Files and Peripheral Examples (including F281x)  (ZIP 1308 KB )    2,437 views, 04 Aug 2009  ”

解压后安装setup_DSP281x_v120.exe，选择默认地址，然后在以下地址可以找到所有281X系列的CMD。

C:\TI\c28\DSP281x\v120\DSP281x_common\cmd

里面的F2812.cmd就是跑在FLASH上的CMD文件。里面的有效内容如下，相对RAM的CMD，多加了FLASH的地址分配，你可以对照Memorymap来看怎么分配的。

我用的DSP2810，在线仿真时需要调用CMD文件，手头上只有对应2812的cmd文件F2812_EzDSP_RAM_lnk.cmd，请问哪里可以下到2810的。如果我自己从2812的cmd上改需要怎么怎么做？另外，我的产品最终在运行时，需要在运行过程中将一些参数存储到片上FLASH里，防止掉电时丢失，要怎么操作？没找到例程。

谢谢您，我安装了TI的例程，但在C:\TI\c28\DSP281x\v120\DSP281x_common\cmd里关于2810的cmd文件就一个，就是F2810.cmd，并没有2810在线仿真用的cmd文件啊

F2810.cmd就是可以下载到FLASH去的CMD，你所指的在线仿真用的CMD是增加了哪些段还是有其他设置？
