Other Parts Discussed in Thread: OMAPL138, SYSBIOS

I am trying to run the EDMA3 LLD (C:\Program Files (x86)\Texas Instruments\edma3_lld_02_11_01_02\examples\edma3_driver\evmOMAPL138\sample_app) example code and have the following undefined symbols. What could be causing this?

    Folks,

    Could I please get some help on the above and thsi(http://e2e.ti.com/support/embedded/f/355/p/105429/372113.aspx#372113)? I am dead in the water until I can get past these unresolved symbols. 

    Thx,

    MikeH

    Mike,

    have you changed anything in the extracted package of edma3_lld_02_11_01_02?

    This version of EDMA uses make based build and build procedures are given in the user guide as well.
    refer to packages\ti\sdo\edma3\drv\docs\EDMA3_Driver_User_Guide.pdf

    Following are the steps I used to build.

    After extracting the package, In makerules/env.mk file change the variable INTERNAL_SW_ROOT to the edma package extracted dir and make sure the variables UTILS_INSTALL_DIR, bios_PATH and xdc_PATH are pointing properly to the installed tools.

    while building ser the ROOTDIR env variable to edma package extracted dir.

    To build examples for all the platforms issue following commands from the <edma extracted dir>\packages
    $gmake examples FORMAT=ELF
    $gmake examples FORMAT=COFF

    If you want to build only for omapl138 dsp core you can issue the following command from the <edma extracted dir>\packages
    $gmake edma3_drv_omapl138_sample

    Please check if you are doing anything different from above mentioned steps.

    Prasad,

    Are the pre-built library files not already available in the \lib\674\debug directory? (i.e. C:\Program Files (x86)\Texas Instruments\edma3_lld_02_11_01_02\packages\ti\sdo\edma3\drv\lib\674\debug).  Could I not simply link to these existing files?

    Mike,
    You should be able to link to the pre-built libraries.
    Can you tell me how exactly you are trying to build the examples?

    Prasad,

    Thanks for the help, but I have given up on SYSBIOS for the time being.

    Prasad:

          What is the extension of pre-built library files   in edma packet? I search edma3_lld_02_11_03_03 , can not find any lib file.
