EDMA3 Undefined Symbol Error

Hi,

I'm getting this link error while linking EDMA 3 sample project for TCI6616

error: unresolved symbols remain
error: errors encountered during linking;
   "edma3_drv_bios6_tci6616_st_sample.out" not built

 

I tried giving search path in Link options to "edma3_lld_drv.ae66"

Then I got this error

 

fatal error: cannot open file "D:\Program Files\Texas Instruments\edma3_lld_02_11_01_02\packages\ti\sdo\edma3\drv\lib\66\debug":

(I'm using CC4.3)

Where am I doing wrong...

 

Regards

    Hi, There will be additional modifications in progress for building the EDMA examples through the project. This includes modifying the target to C66x and using ELF instead of COFF. For version 2.11.01.02 examples can be built using command line make. Please refer to the section 2.4.2 of EDMA3_Driver_User_Guide.pdf for instructions to build using makefile infrastructure.

    Hi

    Thanks for the response.

    I had already set it to C6xx and ELF, didn't work out.

    I tried using the the command line and it stopped at the error:

    /cygdrive/c/progra~1/texasi~1/xdctools/bin/cp : can not create regular file 'obj/tci6608-sim\c6xdsp\debug\edma3_drv_tci6608_sample_configuro/linker_mod.cmd : Permission Denied

    I'm using windows 7, any problem with security or something else?

    Hi ,

    Windows 7 and cygwin environment  are two variables. First can you please check if short path "c:/PROGRA~1/TEXASI~1/" is valid by just doing cd to the directory.

    Secondly can you try without cygwin environment . Here are the steps you would need to do:

    1) Set PATH to XDC to pick the gmake. Example assuming below directory exists

    set PATH=C:/PROGRA~1/TEXASI~1/xdctools_3_20_07_86

    2) Set ROOTDIR

    set ROOTDIR=C:/PROGRA~1/TEXASI~1/edma3_lld_02_11_01_02

    3) Update the edma3_lld_02_11_01_02\makerules\env.mk with the correct path for

    INTERNAL_SW_ROOT , EXTERNAL_SW_ROOT , UTILS_INSTALL_DIR ,CODEGEN_PATH_DSPELF

     

    4) Build examples by  gmake -f makefile_c66x examples FORMAT=ELF

    Regards

    Raghu

    I had a similar issue with the following error message:

    fatal error: cannot open file

       "obj/c6472-evm/c6xdsp/debug/edma3_drv_c6472_sample_configuro/linker_mod.cmd" :  Permission denied

     

    The way to fix it was to right click on file linker_mod.cmd, select properties and the Security tab. Then click Edit and check all the boxes under the column 'Allow' .

    Must be an issue with cygwin and win 7. Cygwin is creating files with no access permissions.

     

    I had to do the same procedure for many files, which is quiet tedious. If there is a better solution, can somebody let me know ?

     

    I hope that TI will start making their release with CCS-based project build instead of command line. Command lines build often lead to problems due to dependencies with cygwin, xdc, windows, etc and customers spend too much on these issues. CCS is a great IDE and it is odd that TI's own software modules don't leverage its build capabilities.
