EDMA3 LLD Bios 6 unresolved symbols errors?

Other Parts Discussed in Thread: OMAP-L138, SYSBIOS

 

I am working on an OMAP-L138 project that includes the use of the latest EDMA3 LLD package for bios 6 (C:\Program Files (x86)\Texas Instruments\edma3_lld_02_11_01_02). I have used the same project code in a previous project that used bios 5 LLD, and am in the process of transferring to bios 6. I have added links to 4 seperate library (OMAP debug) files in the new new LLD package.

edma3_lld_drv.ae9

edma3_lld_drv_sample.ae9

edma3_lld_rm.ae9

edma3_lld_rm_sample.ae9

I have also provided include links to each of the folders that contain the .h files for these libraries, and included the following includes in my code.

#include <edma3_drv.h> // LLD Driver header file 

#include <edma3_rm.h>

#include <edma3_common.h>

#include <bios6_edma3_drv_sample.h> // OS-specific and device-specific header file

#include <src\edma3_rl_cc.h> // needed for the EDMA3_CCRL_RegsOvly global (for debug) 

However, when I build the project I get the following linker errors. Am I forgetting a link somewhere?

    Ok. So the OMAP team punted me out of their sandbox back into the BIOS sandbox. Must be on a tight quota system......

    It appears as though the EDMA2 LLD for bios 5 had pre-made .lib files and the EDMA3 LLD for bios 6 does not. Hence my attempt to link to the wrong files above.

    Is this true? If so, can someone give me a clue as to how I (re) build the entire EDMA3 LLD library so that I can link to .lib files?

    Guidance appreciated.

    Thx,

    MikeH

    Mike,

    Look in the EDM3 release notes and/or User Guide. It talks about how to build the libraries.

    Todd,

    Can you be a bit more specific? I looked through the release notes, and they say :

    Hence libraries need to be built

    through command prompt using gmake command (Please refer the user

    guide available with this release for detailed build instructions).

    But I find no User Guide with this package. I have no clue how to build the libraries.

    Thx,

    MikeH

    Mike,

    Look in the Help->Help Contents in CCS. You should see a EDMA3 product with several different documents. (Or at least I see several docs with the EDMA3 2.10.02 that I have installed.) You could also look in the <edma3>\packages\ti\sdo\edma3\drv\docs directory (note: the directory structure might be different for your version).

    Mike,

    Steps to build the libraries and the stand-alone application are  given in EDMA3_Driver_User_Guide.pdf in edma3_lld_<<version_number>>\packages\ti\sdo\edma3\drv\docs folder. Refer to the steps mentioned in "2.4 Integration Guide" in the document.

    Todd, Prasad,

    Thanks guys. I had stopped at C:\Program Files (x86)\Texas Instruments\edma3_lld_02_11_01_02\docs when looking for the User Guide. Is there some reason why the User Guide, and other docs, are not in the above folder?

    Thx,

    Mike

    Sorry to reject the answer, but this is still a problem. I believe I mis-understood what I should be linking to in the EDMA driver. Apparently the ".a674P" files *are* library files (is this true?). If so, why do I get the "undefined symbol" errors above in my original post?

    Thx,

    MikeH

    Mike,

    I wasn't sure by looking at this thread whether it overlapped with other threads you were pursuing simultaneously.  Are you still working this particular issue and getting these build errors?

    No. I have given up on SYSBIOS for the time being.

    thx

    Was there a resolution to this issue? I am having the same problem with my build using the sample libraries.
