Build errors while using codec engine examples with custom DSP library

Hi,

               We are trying to work with videodec_copy in codec engine examples. When we are building the codecs for videodec_copy it is generating " viddec_copy.a64P, viddec_copy.a64P.mak, viddec_copy.av5T, viddec_copy.av5T.mak ". Then we are building the servers and then the application, it is working fine.

               We took the same source files present in viddec_copy to CCS and generated the viddec_copy.a64P and by placing that in codecs/lib folder it is working fine.

The probem is........

               We are not able to generate " viddec_copy.a64P.mak, viddec_copy.av5T, viddec_copy.av5T.mak " in CCS. When we give the CCS generated library in codecs lib replacing the original one it is working fine but when we remove viddec_copy.av5T we are geting error while bulding the applicaion.  We are getting the following error generated while building apps folder..

Why we need this viddec_copy.av5T ?

 

Thanks and Regards,

    I updated this article to add details about what you're seeing:

    http://tiexpressdsp.com/index.php?title=Codec_Engine_FAQ#Why_does_my_GPP-side_application_try_.28and_fail.21.29_to_link_in_a_DSP-side_library

    If you're modifying the viddec_copy example package to only provide a C64P lib (i.e. viddec_copy.a64P), it shouldn't return a library for any other target, so it's getLibs() fxn will need to be modified - an example is provided at the article above.

    Hi,

    Thanks a lot for you help.

    After modifying package.xs only for .a64P , I could build servers and codecs sucessfully.

    But when i try to run application.. (..apps/video_copy/dualcpu/evm3530) , it is throwing the following error :

    I would like to build my application on ARM and library completely on DSP.

    Can you please suggest me where can i modify to run my library on DSP and application on ARM.

    Check your XDCtools version, and also examples/user.bld.  In Codec Engine 2.23.01 (and also 2.22), the published examples/user.bld set the target's LONGNAME when its name is "GCArmv5T"; this works for me with XDCtools 3.10.03.
