I am not an expert on this topic, but I do know there are known issues with DMA and the accurate cycle simulator.  Since ACPY3 API is DMA related, this could explain this behavior, although I would not think this should cause a hang (just not very accurate cycle count data).

I believe we are testing a solution for DMA and cycle accurate simulator, but this is not available on the update advisor site yet, hence please stay tuned.

With regards to getting CCS software updates, again this is not my area of expertise so perhaps someone else can explain why you would have problems using update advisor, but you should be able to find these updates by visiting the update advisor website directly using the link below

Hi Sandeep,

I am currently working on TMS320DM6446 using Code Composer Studio 3.3.38.2.
 

Also I'm doing optimization, I tried to use ACPY3 modules, it's regret I havn't succeeded all the time.

The error is follow:

could you tell me that using ACPY3 modules needs include which header files? or other files and needs attentive things.

Thank you a lot

William

Sandeep may have additional feedback as to specifically how to include the ACPY3 library, but I can say that this is a library and not a header file you need, since this is the linker complaining and not the compiler (linker dereferences all objects to their actual files, and it could not find the ACPY3_start function's binary). It is probably in some binary within framework_components_x_xx_xx\packages\ti\sdo\fc\acpy3 as mentioned in my prior post.

Hi william,

It looks like u havent included the ACPY3 library.

It can be found at

C:\dvsdk_1_01_00_15\framework_components_2_10_01\packages\ti\sdo\fc\acpy3\acpy3.a64P

you can download the latest framework component from TI website.

hope this would resolve your problem, if not do let me know.

regards,

Sandeep

Hi Bernie and Sandeep,

Thanks for your help, when I include the ACPY3 library in my project, it can be compiled successfully.

Thanks a lot!

Hi Sandeep,

I want to transfer CIF video data from Encbuf[] to Decbuf[]; follow is the codes of Y componet I adopt:

    ACPY3_activate(h);
    ACPY3_wait(h);

    p.transferType          = ACPY3_1D2D;
    p.srcAddr                 = Encbuf;        // char  //the first Y line of plane YUV420
    p.dstAddr                 = Decbuf;            

    p.elementSize           = 1;
    p.numElements          = 352;
    p.numFrames            =1;

    p.dstElementIndex     = 2;
    p.srcFrameIndex        = 1;
    p.dstFrameIndex         = 1;
    p.waitId = 0;

    ACPY3_configure(h,&p,0);
    ACPY3_start( h );
    ACPY3_wait( h );

all the code above loop to 288 times and finish one frame .

when run above codes, the value of Decbuf[] is not change, I can't find where I configure error, or I miss to set some parameters !

Please help me! Thanks a lot!
