标题: dsp的cmd问题（仿真器和写flash运行结果不同） [打印本页]

作者: charlie1982 时间: 2011-8-9 15:40 标题: dsp的cmd问题（仿真器和写flash运行结果不同）

求助：
我在我的dsp中做一个滤波，使用仿真器时，滤波后的波形正确的（使用28335_RAM_Lnk.cmd），但是在写进片子中运行时波形就成直线啦(使用28335.cmd)
使用同一个cmd（28335.cmd）在把程序中滤波注释掉后，也就是不进行滤波写进片子运行，波形正常
哪位大侠帮我找找原因！！
谢谢！！！
28335.cmd：

/* Define the memory block start/length for the F28335
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections

Notes:
      Memory blocks on F28335 are uniform (ie same
      physical memory) in both PAGE 0 and PAGE 1.
      That is the same memory region should not be
      defined for both PAGE 0 and PAGE 1.
      Doing so will result in corruption of program
      and/or data.

      L0/L1/L2 and L3 memory blocks are mirrored - that is
      they can be accessed in high memory or low memory.
      For simplicity only one instance is used in this
      linker file.

      Contiguous SARAM memory blocks can be combined
      if required to create a larger memory block.
