2810在线仿真和flash操作

Other Parts Discussed in Thread: TMS320F2812

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。

  • 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?
