Elf Output format in ccs4.0

Hi
I was wondering if it is possible to obtain elf output from ccs 4.0 for C6xxx series processors.  I couldn't find the relevant switch/settings from the build settings, even though there is dwarf option in the debug options.
Thanks

    ELD output for C6000 executables can be created using the 7.x version of the C6000 codegen tools.  You can get a version here: https://www-a.ti.com/downloads/sds_support/TICodegenerationTools/download.htm, though for ones that integrate into CCS, you may need to use the update tool in CCS.

    See here for more details of ELF (EABI) support.

    Regards, Daniel

     Thanks for quick & accurate reply.

    New question : I am not using any dsp/bios or psp drivers, all my project  needs is rts6740.lib in elf format. Do you foresee any release of this file in near future (1 month or so)?

    Regards

    Update : I've found this link and will give it a shot.

    The codegen tools should include versions of the rts libs compiled in ELF format using the EABI.  in the lib directory, there should libraries with _elf or _elf40 in the file name.  See the chapter 8 of the compiler user's guide about RTS lib naming conventions.

    Hi,
    I just chanced upon this post.
    I'm using Version: 4.1.0.02006 of CCS. And 7.2.0A10266 of the cgtools. I guess it's possible to obtain an executable for C674x core.
    The real question is can this CCS version load a elf formatted .out to target, execute and debug?

    Hi,
    The configuration I use ( 4.1.2.00027 and 7.0.3A10161 )  can load, execute and debug an 6747, so I assume your configuration can do also. The trick/ problem I encountered was in the load state. Upon starting debug, CCS somehow does not load the program as it does in Coff executables, even though I set the debug settings correctly. I need to specifically point your executable by "Target - Load program" each time I start debugging. After that, it is same as in coff .

    Regards
