我是新手,刚学CLA模块,遇到一个问题:为什么28379D的CLA例程cla_fir32_cpu01中的任务cla1Task1只能触发一次,第二次就触发不了,而程序中是循环触发了133次?希望大佬们不吝赐教,跪谢!

还有就是,明明程序中给CLA申请LS5作为程序空间,为什么CLA程序运行时的起始地址是LS4?是例程错了吗?

Susan Yang:

请问您是如何调试的?能否给出相关截图?

请您先参考下:

software-dl.ti.com/…/debugging.html

software-dl.ti.com/…/getting_started.html

在cmd文件中,

RAMLS4_5: origin = 0x00A000,length = 0x001000

/* CLA specific sections */Cla1Prog: > RAMLS4_5, PAGE=0

关于此,您可以看一下数据手册的 表 6-1. C28x Memory Map

多谢解惑,十分抱歉,我用的公司电脑,不能上传图片。。
我采用单步调试,程序采用循环的方式重发触发任务1,第一次任务1运行完成,MIRUN[0]变为0后,第二次触发任务1,对应的MIFR和MIER相应的位都置1了,且CLA处于空闲状态,但是CLA就是不会再次运行任务1.

请问在cmd文件中
RAMLS4_5 : origin = 0x00A000, length = 0x001000

/* CLA specific sections */
Cla1Prog : > RAMLS4_5, PAGE=0
对应的程序存放空间是不是LS4?但是例程中是将LS5分配位CLA的程序空间,我不清楚是例程出错了,还是我理解出错了
例程中相关程序是这样的:
MemCfgRegs.LSxMSEL.bit.MSEL_LS4 = 1;
MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS4 = 1;

Susan Yang:

我测试了一下程序是可以正常运行的,如下图:

所以建议您还是按照之前链接的调试说明来调试一下

user6574429 说:/* CLA specific sections */ Cla1Prog : > RAMLS4_5, PAGE=0 对应的程序存放空间是不是LS4?但是例程中是将LS5分配位CLA的程序空间,我不清楚是例程出错了,还是我理解出错了 例程中相关程序是这样的: MemCfgRegs.LSxMSEL.bit.MSEL_LS4 = 1; MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS4 = 1;

参考程序内说明

//// Select LS4RAM and LS5RAM to be the programming space for the CLA// First configure the CLA to be the master for LS4 and LS5 and then// set the space to be a program block//MemCfgRegs.LSxMSEL.bit.MSEL_LS4 = 1;MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS4 = 1;MemCfgRegs.LSxMSEL.bit.MSEL_LS5 = 1;MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS5 = 1;

在cmd文件内将LS4 LS5合并了,但是在c文件内,LS4 LS5的设置是分开的,如上面的语句

其实均表示使用的地址是 RAMLS4_5定义的地址范围

,

user6574429:

你好,非常感谢你的回复,我想问一下你运行程序的时候CLA的任务1执行了多少次?我的只执行了一次就不执行了,而且例程里只有MemCfgRegs.LSxMSEL.bit.MSEL_LS5 = 1;
MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS5 = 1;
LS5的内存分配。

Susan Yang:

clar任务执行了多次

在cla_fir32_cpu01.c的void CLA_configClaMemory(void)内的341到344行

//
// Select LS4RAM and LS5RAM to be the programming space for the CLA
// First configure the CLA to be the master for LS4 and LS5 and then
// set the space to be a program block
//
MemCfgRegs.LSxMSEL.bit.MSEL_LS4 = 1;
MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS4 = 1;
MemCfgRegs.LSxMSEL.bit.MSEL_LS5 = 1;
MemCfgRegs.LSxCLAPGM.bit.CLAPGM_LS5 = 1;

user6574429:

请问每次进入CLA程序都会停在__mdebugstop()吗?我的是第一次进入时停在这,然后单步调试至MSTOP后就再也没进入CLA的任务1了
但是CLA中的寄存器是这样的

,

user6574429:

您好,能分享一下CMD文件吗?我看一下是否是我的CMD文件有错?

,

Susan Yang:

“请问每次进入CLA程序都会停在__mdebugstop()吗?”

是的
