280049 cla内核 与.c核共用变量使用问题

user4513027

Other Parts Discussed in Thread: TMS320F280049

定义一个数组变量，如何在在cla内核中和.c核中都能够使用？我以下操作，发现给数组变量赋值经常出现问题，会把给数组0赋值的变量莫名其妙的给数组1赋值，请问有什么问题？

CMD文件数据空间:

   RAMLS0           : origin = 0x008000, length = 0x000800

   DqDataRam        : > RAMLS0,     PAGE = 1

设置 RAMLS0 为cla内核使用数据空间

MemCfgRegs.LSxMSEL.bit.MSEL_LS0 = 1;
MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS0 = 0;

#pragma DATA_SECTION(fClaView, "DqDataRam ");
float fClaView[21];

在cla内核中给变量

fClaView[0] = 1001;

结果 fClaView[0]未等于1001  fClaView[0]等于1001,fClaView[0]还是等于0，fClaView[3]程序中从未使用过

    1.1平台描述

    使用TMS320F280049芯片 

    编译器平台ccs8.3.0  

    编译器版本:TI v18.1.4.LTS

    1.2 Cla内核CMD内存分配

              Cla核数据空间:

           RAMLS0_1         : origin = 0x008000, length = 0x001000

                RAMLS2_3         : origin = 0x009000, length = 0x001000

    Cla核程序空间:

       RAMLS4_5_6_7       : origin = 0x00A000, length = 0x002000

         程序空间寄存器配置:

        MemCfgRegs.LSxMSEL.bit.MSEL_LS4 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS4 = 1;

        MemCfgRegs.LSxMSEL.bit.MSEL_LS5 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS5 = 1;

        MemCfgRegs.LSxMSEL.bit.MSEL_LS6 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS6 = 1;

        MemCfgRegs.LSxMSEL.bit.MSEL_LS7 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS7 = 1;

     

         数据空间寄存器配置:

                  MemCfgRegs.LSxMSEL.bit.MSEL_LS0 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS0 = 0;

        MemCfgRegs.LSxMSEL.bit.MSEL_LS1 = 1;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS1 = 0;

        MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS3 = 0;

    1.3问题描述

       在Cla内核中定义结构体变量

      Struct_SourceVector              strBypVoltageVector;

              在.c文件中给这个结构体变量的元素赋值：

                  strBypVoltageVector.phaseA         = 1;

                  strBypVoltageVector.alpha          = 2;

                  strBypVoltageVector.alphaPos       = 3;//strBypVoltageVector.phaseA;

                  strBypVoltageVector.beta            = 4;

                  strBypVoltageVector.betaPos        = 5;//strFifoOutputVoltAlpha.beforeOneFourthData;

             程序烧录并调试(通过SCI串口方式把DSP数据用电脑显示，用这种方式查看变量目前为止并未出现过错误，故可以排除通讯与显示造成的问题)

              但是发现变量strBypVoltageVector.alphaPos 和 strBypVoltageVector.betaPos的值并不等于3和5，而是等于0，通过Map文件往结构体strBypVoltageVector变量地址附近查找，发现strBypVoltageVector结构体变量地址000081b4上面的地址 fGridVoltAxisQFliterInteg1  00008186与fGridVoltAxisDFliterInteg1 00008188变量改变并等于3和5(这两个变量程序中从来没有用到), 

           具体结构体定义与相关变量地址如下:

    //电压数据结构体

    typedef struct

    {

        float phaseA;

        float phaseB;
