器件型号：TMS320F28P550SJ
主题中讨论的其他器件：SysConfig、 C2000WARE

在 Code Composer Studio 中、我导入了一个 DSP RFFT 示例项目。它附带"RAM"和"flash"构建配置。工程定义了一些存储 RFFT 数据的内存段(例如 RFFTdata1)。 RAM 配置有针对这些区域的定义、如下所示：

    //
    // User Sections
    //
    RFFTdata1 {  }         >  RAMGS3,
                              ALIGN(512)
    RFFTdata2 {  }         >  RAMGS3
    RFFTdata3 {  }         >  RAMGS3
    FPUfftTables {  }      >  RAMGS3
    RFFTdata4 {  }         >  RAMGS3
    FPUmathTables {  }     >  RAMGS2

该工程使用 SysConfig、我也尝试在闪存配置中定义此类存储器区域、因为在那里未定义它们(未定义它们会导致代码行为不正确)。

但是、当我在 SysConfig 中将 RFFTdata1添加到用户定义的段时、我会收到错误

错误：generic_ram_lnk (/utilities/cmd_tool/cmd_syscfg/source/CMD) userSection[0].$name：重复名称："RFFTdata1"也存在于用户定义段的实例上
错误：generic_flash_lnk (/utilities/cmd_tool/cmd_syscfg/source/CMD) userSection[0].$name：重复名称："RFFTdata1"在用户定义段的实例上也存在

SysConfig UI 中和编译代码时都会出现此错误。请注意、生成链接器脚本(device_cmd.cmd)使用预处理器指令来选择要使用的存储器配置、因此不应将 RFFTdata1视为重复、请参阅下面的(为清晰起见而缩短了)：

#ifdef generic_ram_lnk

MEMORY
{
    ...
}


SECTIONS
{
    ...
}

#endif
#ifdef generic_flash_lnk

MEMORY
{
    ...
}


SECTIONS
{
    ...
}

#endif

/*
//===========================================================================
// End of file.
//===========================================================================
*/

如何在闪存配置中将所需的 RFFTdata 段添加到链接器脚本？

谢谢。

您好！

您能否共享工程和 SysConfig 文件以供查看？

此外、在 Project 属性中检查是否为闪存配置定义了预定义符号(GENERAL_FLASH_lnk)。

您好！

当然、该工程与 C2000ware 中的示例工程 dsp_rfft_fpu32_f28p55x 相同。

这是 SysConfig：

我还在项目属性中检查了 GENERAL_FLASH_lnk 是否处于闪存配置中。
