TMS320F280049C: CLA内存配置问题

user6223372

Part Number: TMS320F280049C
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

我在sysconfig tool中将RAMLS3配置为共享区域，将RAMLS4配置为CLA程序区域，其余LS区域配置为CPU区域，生成的board.c相关程序如下：

//*****************************************************************************

//*****************************************************************************

void myCLA0_init(){
	//
    // Configure all CLA task vectors
    // On Type-1 and Type-2 CLAs the MVECT registers accept full 16-bit task addresses as
    // opposed to offsets used on older Type-0 CLAs
    //
#pragma diag_suppress=770
    //
    // CLA Task 1
    //
    CLA_mapTaskVector(myCLA0_BASE, CLA_MVECT_1, (uint16_t)&Cla1Task1);
    CLA_setTriggerSource(CLA_TASK_1, CLA_TRIGGER_SOFTWARE);
#pragma diag_warning=770
	//
    // Enable the IACK instruction to start a task on CLA in software
    // for all  8 CLA tasks. Also, globally enable all 8 tasks (or a
    // subset of tasks) by writing to their respective bits in the
    // MIER register
    //
	CLA_enableIACK(myCLA0_BASE);
    CLA_enableTasks(myCLA0_BASE, CLA_TASKFLAG_1 );

在程序中，定义了结构体strVoltPiCtrl，并将其放到了“CLADataLS1”中，同时在100kHz的PWM中断中使用软件触发的形式触发CLAtask1，

CLA_forceTasks(myCLA0_BASE,CLA_TASKFLAG_1);

并试图在PWM中断中对结构体的某些值进行修改，并在CLA中通过这些值进行进一步的计算，并将结果幅值给结构体中的另外一些元素

#pragma DATA_SECTION(strVoltPiCtrl,"CLADataLS1");
PI_CTRL_MODULE strVoltPiCtrl;

结果在进行Debug时，发现结构体strVoltPiCtrl所处的内存区域为Program区域

导致在Debug模式下，必须先手动connect CLA核，整体程序才能运行，若将程序烧写到Flash，则整体程序将无法运行

经过测试，将100kHz中断中的软件触发CLA屏蔽，或者将PWM中断中屏蔽与该结构体相关的语句，再将程序烧写到FLASH后，则程序又能正常运行，

请问：1.为什么结构体所对应的内存区域为program区域；2.程序为何无法正常运行

另外，使用Debug模式，connect CLA核及load symbol后，在Expressions窗口所监视的变量值均是0，但在CPU核的监视窗口则变量均有变换。监视的变量均已放在message内存区域以及CPU和CLA共享的LS内存区域

您好，

看起来您的 CLAdataLS1部分已分配给链接器 cmd 文件中的 RAMLS3存储器范围。这是故意的吗？ LSRAM3从地址0x009800开始、长度为0x000800、因此如果 strVoltPiCtrl 的长度为0x009900、则这是正常现象、因为它处于该值范围内。是否尝试让 strVoltPiCtrl 成为 CPU 和 CLA 之间的共享变量？如果是、您是否有一个头文件的 strVoltPiCtrl 变量的外部文件在.cla 文件和 main.c 文件中都包含#include？

但是我已经在内存配置时将RAMLS3配置成了MEMCFG_CLA_MEM_DATA，那么这一块区域不应该就是CLA和CPU之间的共享数据内存区域了吗。另外， .cla文件和对应的.c文件都#include了相关的外部变量

您好，

我有点困惑。您是否希望strVoltPiCtrl被放置在LS4中，因为它专用于程序存储器？以下是您选择的sysconfig MEMCFG，是否正确？或者我是否已切换LSRAM3和LSRAM4？

如果希望CPU和CLA都具有strVoltPiCtrl变量的写入访问权限，则需要将其分配给与具有共享访问权限的LSRAM相关的输出部分。 #pragma将告诉编译器将符号放在您指定的输出部分，无论它是否具有共享内存权限。

我建议尝试尽可能少地修改C2000ware中给出的链接程序cmd文件，以避免出现问题。
