你好，工程师
我在使用am2732开发板进行HWA相关功能的开发。我将HWA的Paramset的触发方式设置为HWA_TRIG_MODE_DMA，loopCnt为4；在使用CCS进行Debug的过程中发现这组paramset可以由DMA触发，并且正常完成第一个loop的处理，然后由EDMA将数据从hwa membank搬移到L3上，然后由该EDMA触发chain的EDMA通道搬移第二个loop需要的数据到HWA的membank中。在CCS上通过内存查看，第二个loop的数据已经成功搬移到HWA的membank中了，但是没有触发HWA的paramset进行处理，此时查看寄存器loop_cnt的值为2，但是hwa的dest membank中的数据仍为第一个loop的处理结果，即第二个loop没有开始处理；请问为什么会发生上述的问题？loop_cnt=2是否说明hotSignature已经将寄存器DMA2HWA_TRIG中对应的bit进行置位了？
谢谢

代码参照了SDK中 HWA数据解压缩的代码
你好，工程师
经过测试，我发现可能为函数DPEDMAHWA_configOneHotSignature配置的Ccnt有问题，我将hotSignature的值配置为HWA的loopCnt后，可以成功执行所有的loop，并正常输出到L3上；在SDK中，该函数配置hotSignature的Ccnt=1；请问为什么在我的CCS代码中，该Ccnt耗尽之后不会重新加载？
谢谢
感谢您对TI产品的关注！由于问题比较复杂，已将您的问题发布在E2E英文技术论坛上，由资深的英文论坛工程师为您提供帮助。工程师需要一些时间看一下问题。

你好
我们发现在配置EDMA paramset时，实际使用的EDMA paramset配置没有问题，但是配置的shadow EDMA paramset的参数存在问题；通过查看shadow paramset的寄存器得知，该参数与预设的不同，导致实际的EDMA cnt耗尽之后link到shadow EDMA paramset，拷贝得到的参数配置有问题，导致上述的问题出现；请问，为什么shadow EDMA的配置会有问题？在配置shadow EDMA之前我尝试打印各参数的值，均正常；使用的函数如上附的代码所示是DPEDMA_setup_shadow_link。
谢谢
你好，工程师
我最终定位到了问题，在函数DPEDMA_setup_shadow_link中有一个变量edmaParam，该变量在使用函数EDMA_ccPaRAMEntry_init进行初始化后，使用“=”进行结构体赋值，edmaParam = *config; 在赋值后，导致出现了2Byte的偏移，使参数出现错位，导致最终配置的paramset错误；
我不使用等号进行结构体赋值后，参数配置正常，程序也能正常运行了；
请让专家帮忙确认，该问题是否是由结构体赋值方式引入的。
谢谢
