Hi, Bill

      I want use QDMA to transfer 1K data , but I cannot complete the code. This is all I got. Would please modify it for me please. I would appreciate it very much. I referred an example in MCSDK, but it don't help for I don't have evm6657 ,I can't find the context of the function like“EDMA3_DRV_setQdmaTrigWord”, so I don't have a  clue of the functions in it . I just need an example CSL.

     Best wishes.

    Alex..

Hi, xiaohui

      Thank you very much. I installed BIOS_MCSDK but I don't have pdk_C6678 on my computer. Is this sofeware free for use? By the way the CCSv5.5 I am using is free too.

     Why I cannot find the folder pdk_C6657, maybe I did't install it rightly...

        Regards
