running voice lib from TI on C674x

Hi, I am trying to run some test on the voice lib 1.0.0.1 on C674x dsp and run into problem after downloading it from TI website. In particular, I am interested in the ECU module. I have several questions and do not know if any one has experience with it.

  1. Does this voice lib module have to work with xdc platform? Can I use the directly without XDC help by link it to a simple CCS 3.3 project? I am fine with the upper level APIs, but not sure if it assumes any system service such as memory allocation, etc.
  2. I’ve downloaded and installed XDCtools\xdc\xdctools_3_20_08_88 and also CCS 4.2.3.0004. But I have trouble to build/test the voice lib testbeds using either command line xdc environment or CCS 4.2 environment
    1. I followed voice lib\ecu document and was trying to run cygwinxdc.bat to setup build environment, foolowing the document file:///C:/Program%20Files/Texas%20Instruments/volib_C64P_1_0_0_1/docs/doxygen/html/ecu_test_html/index.html, but it seems that it assumes some tools to be installed in c:\tools directory and i: drive. Is there a document showing the installation/building process for voice lib modules?
    2. Is there any document on using CCS 4.x to build and test voice lib testbeds?
    3. I tried to build a simple ECU testbed using the a64P libary in a CCS 3.3 project, I could not find and link even if I only include on ecu function ecuNew, as some of the function calls are not included, after I link the rts for C64 and util and ecu lib from the voice lib. The list of the not function could not be linked is listed below. Is there a version mismatch for this version of voiceLib or is it a requirement that it has to be run above the XDC platform?

 

thank
