CCS 4 support of TMS320C6727

Other Parts Discussed in Thread: SPRC203, TMS320C6727

Does CCS 4 fully support TMS320C6727 with BIOS 5.20, CSL 3.0.9.0, and the ROM fixes from SPRC203?

Can you please confirm.

Thanks,

Dave

    CCSv4 only supports BIOS 5.41and later.

    Migration from BIOS 5.20 to 5.41 should be straightforward -- just rebuild the configuration and relink.

    Unfortunately, BIOS 5.41 is not compatible with the BIOS-in-ROM (which is BIOS 5.20).

    If you want to use BIOS in the 6727 ROM, then you need to use BIOS 5.20 and CCSv3.

    That's very interesting.  From the current pricing structure and lack of support for Windows 7, it appears that CCS 3.3 is being phased out.  Does this infer that the c6727 is a dead-end product, or is there intent to fully support it in an updated version of CCS 4?

    6727 is supported with CCSv4.x and BIOS 5.41.

    If they have room in their RAM and can run BIOS from RAM instead of ROM, then they can use CCSv4.x and BIOS 5.41.

    ROM compatibility is very difficult to manage.   Unfortunately, the ROM is tied to a specific version of BIOS (and point releases to that).

    This is accurate

    6727 is supported with v4. BIOS 5.20 is not. Karl was referring to using BIOS in ROM using v5.20

    You can build applications with BIOS 5.20 in CCSv4.  However you will not have any ROV or RTA functionality.  You will need to download and install BIOS5.20 and then from Windows->Preferences, type RTSC in the search box and point CCS to where BIOS is installed.  You can then setup a project to build with BIOS 5.20

    Hi John,

    I would like to use DSP/BIOS form the C6727 ROM.  I am trying to follow the steps you provided.  I had previously downloaded DSP/BIOS v5.20.05 in an earlier attempt to get this working.  I launched CCS4 and typed RTSC in the filter of the Windows->Preferences window.  In the resulting RTSC frame there are several fields (e.g. "ISA Family", "Code Generation tools",etc.) and a tab "Product and Repositories" with a tree structure.  In this tree structure I have three entries under DSP/BIOS: 6.62.00.13, 5.41.02.14, 5.20.05.  I checked the box beside 5.20.05, but I'm not sure what effect this had.

    Now I tired to create a new CCS Project where I select DSP/BIOS version 5.20.05.  I selected padk6727 as the platform.  When I try to add the BIOS configuration file the following error is displayed:

    js: "C:\Program Files\Texas Instruments\bios_5_20_05\xdctools\include\utils.tci", line 838: uncaught JavaScript exception: Error: Can't find Platform.tc[ip] file for 'ti.platforms.padk6727' (C:\Program Files\Texas Instruments\bios_5_20_05\xdctools\include\utils.tci#838)

        "./TestROM.tcf", line 1
        "./<stdin>", line 4


    Please open C:/Plt/BroadReach/SbSat/Software/Dsp/CcsWorkspace/TestROM/.gconf/TestROM/TestROM.tcf in a text editor and correct any script error(s).  Then reopen the file in the Configuration Tool.
    Or
    Set correct file permissions including generated files if attempting to save this configuration.

    TConf initialization arguments:
    -e environment['config.importPath']='C:/Plt/BroadReach/SbSat/Software/Dsp/CcsWorkspace/TestROM;C:/Program;C:/Program Files/Texas Instruments/bios_5_20_05/packages;' -e environment['config.scriptName']='TestROM.tcf'

    Can you try adding 'C:/Program Files/Texas Instruments/bios_5_20_05/xdctools/packages' to the end of the importPath above?

    Something like this?

    TConf initialization arguments:
    -e environment['config.importPath']='C:/Plt/BroadReach/SbSat/Software/Dsp/CcsWorkspace/TestROM;C:/Program;C:/Program Files/Texas Instruments/bios_5_20_05/packages;C:/Program Files/Texas Instruments/bios_5_20_05/xdctools/packages' -e environment['config.scriptName']='TestROM.tcf'

    Note that you cannot use ROV or RTA for this setup.  BIOS 5.20.05 is not supported in CCSv4.  If all else fails you might have to build externally with a makefile and use CCS as debug environment.
