仿真器和写flash运行结果不同

1万 · 2012-1-26 08:20

楼主做什么东西？不妨详细说说

2万 · 2012-1-26 08:22

我在dsp中做一个滤波，数据在dsp中滤波后将数据发到电脑上，计算机上有单独的软件进行作图处理。

1万 · 2012-1-26 08:23

问题出在哪了

2万 · 2012-1-26 08:24

使用仿真器时，dsp中加滤波后的波形正确的（使用28335_RAM_Lnk.cmd），但是在写进flash后，独立运行运行时波形就成直线啦

1万 · 2012-1-26 08:25

成直线啦？

2万 · 2012-1-26 08:27

使用28335.cmd

1万 · 2012-1-26 08:27

进行滤波写进flash运行呢

2万 · 2012-1-26 08:29

你是说使用同一个cmd（28335.cmd）在把程序中滤波注释掉后?

2万 · 2012-1-26 08:29

正常

1万 · 2012-1-26 08:31

看看你的cmd文件吧

根据sprc095的规则试下把代码从flash　Load到RAM运行试下效果

2万 · 2012-1-26 11:16

下面这段是不是把代码从flash拷贝到ram中运行呢？
ramfuncs          : LOAD = FLASHD,
                     RUN = RAML0,
                     LOAD_START(_RamfuncsLoadStart),
                     LOAD_END(_RamfuncsLoadEnd),

不懂。。。。

2万 · 2012-1-26 11:22

用仿真器做得好好的，波形都是正常的，但是一旦去掉仿真器，写入flash运行就出现波形不正常的现象了

2万 · 2012-1-26 11:22

算了，结贴自己琢磨了

仿真器和写flash运行结果不同
