TI中文支持网我运行TI自带的edma3数据搬移的例子， 搬移2个数组（src1，src2）到2个数组（dst1，dst2）可以成功，但当我再加一个数组，想尝试搬移三个数组（src1,2,3）到dst1,dst2，dst3，就失败了， 该怎么做
Zhan Xiang：
您的描述不太清楚，麻烦说明使用的是哪个用例？操作方式相关信息。

就是TI自带的edma_test.c
myParamSetup.option = CSL_EDMA3_OPT_MAKE(CSL_EDMA3_ITCCH_DIS, \ CSL_EDMA3_TCCH_DIS, \ CSL_EDMA3_ITCINT_DIS, \ CSL_EDMA3_TCINT_EN, \ 0, CSL_EDMA3_TCC_NORMAL,\ CSL_EDMA3_FIFOWIDTH_NONE, \ CSL_EDMA3_STATIC_DIS, \ CSL_EDMA3_SYNC_A, \ CSL_EDMA3_ADDRMODE_INCR, \ CSL_EDMA3_ADDRMODE_INCR ); myParamSetup.srcAddr = (Uint32)srcBuff1; myParamSetup.aCntbCnt = CSL_EDMA3_CNT_MAKE(256,1); myParamSetup.dstAddr = (Uint32)dstBuff1; myParamSetup.srcDstBidx = CSL_EDMA3_BIDX_MAKE(1,1); myParamSetup.linkBcntrld= CSL_EDMA3_LINKBCNTRLD_MAKE(hParamPong,0); myParamSetup.srcDstCidx = CSL_EDMA3_CIDX_MAKE(0,1); myParamSetup.cCnt = 1;
/* Ping setup */ if (CSL_edma3ParamSetup(hParamPing,&myParamSetup) != CSL_SOK) { printf ("Error: EDMA Parameter Entry Setup failed\n"); return -1; }; /* Pong setup */ myParamSetup.linkBcntrld = CSL_EDMA3_LINKBCNTRLD_MAKE(hParamPing,0); myParamSetup.option = CSL_EDMA3_OPT_MAKE(CSL_EDMA3_ITCCH_DIS, \ CSL_EDMA3_TCCH_DIS, \ CSL_EDMA3_ITCINT_DIS, \ CSL_EDMA3_TCINT_EN,\ 1, CSL_EDMA3_TCC_NORMAL,\ CSL_EDMA3_FIFOWIDTH_NONE, \ CSL_EDMA3_STATIC_EN, \ CSL_EDMA3_SYNC_A, \ CSL_EDMA3_ADDRMODE_INCR, \ CSL_EDMA3_ADDRMODE_INCR ); myParamSetup.srcAddr = (Uint32)srcBuff2; myParamSetup.dstAddr = (Uint32)dstBuff2; if (CSL_edma3ParamSetup(hParamPong,&myParamSetup) != CSL_SOK) { printf ("Error: EDMA Parameter Entry Setup failed\n"); return -1; };

我加了一组类似的链接，
myParamSetup.linkBcntrld = CSL_EDMA3_LINKBCNTRLD_MAKE(hParamOut,0); myParamSetup.option = CSL_EDMA3_OPT_MAKE(CSL_EDMA3_ITCCH_DIS, \CSL_EDMA3_TCCH_DIS, \CSL_EDMA3_ITCINT_DIS, \CSL_EDMA3_TCINT_EN,\1, CSL_EDMA3_TCC_NORMAL,\CSL_EDMA3_FIFOWIDTH_NONE, \CSL_EDMA3_STATIC_EN, \CSL_EDMA3_SYNC_A, \CSL_EDMA3_ADDRMODE_INCR, \CSL_EDMA3_ADDRMODE_INCR );myParamSetup.srcAddr = (Uint32)srcBuff3;myParamSetup.dstAddr = (Uint32)dstBuff3; if (CSL_edma3ParamSetup(hParamPong,&myParamSetup) != CSL_SOK) {printf ("Error: EDMA Parameter Entry Setup failed\n"); return -1;} ;
其他的没改，前两组数据可以搬进去， 我自己加的一组就搬不过去了，是不下面的程序要改哪些参数？
/* Interrupt enable (Bits 0-1) for the global region interrupts */ regionIntr.region = CSL_EDMA3_REGION_GLOBAL; regionIntr.intr = 0x3; regionIntr.intrh = 0x0000; CSL_edma3HwControl(hModule,CSL_EDMA3_CMD_INTR_ENABLE,®ionIntr);
/* Trigger channel */ CSL_edma3HwChannelControl(hChannel,CSL_EDMA3_CMD_CHANNEL_SET,NULL);
regionIntr.region = CSL_EDMA3_REGION_GLOBAL; regionIntr.intr = 0; regionIntr.intrh = 0;

hParamOut 是我自己定义的
hParamOut = CSL_edma3GetParamHandle（hChannel,3,&status）;

EDMA有3个要素：
1. 触发方式，event 触发/手动触发/event chain式触发
2. PaRAM配置
3. 触发使能和提交
1.看你的代码你应该用的是手动触发，你要确认你新增的触发源是否和以前的有冲突；
2. 新增触发源对应的PaRAM选择是否正确
3. PaRAM的配置中，参数是否正确，例如使用全局地址
4. 判断传输完成的event 设置是否正确，例如TCC的配置是否有冲突

我新增的触发源和参数配置都是没问题的，TCC是否有冲突是怎么看的？后面这三个函数调用机制我不太懂，搬移2组他调用2次，我搬移三组是否就调用三次？

其实我做的是TCP3E一个传输的任务，只要简单的完成TCP3E传输功能 ，不使用BIOS 他的EDMA3需要传输 配置信息和输入数据进入TCP3E，然后传输turbo encoder后的结果出来 ，所以我感觉edma3 需要三次传输。

建议不要直接增加代码，你先理解清楚样例中的实现是如何对EDMA进行操作的，之后再按照你的需求进行修改。
