CCS: The latest version of CCS/CS for developing TMS320VC5471ZHK

Tool/software: Code Composer Studio

Hi,

The current product developed 10 years ago and used TMS320VC5471ZHK on its control board. It was a multicore DSP including one C54 DSP and one ARM7TMDI MCU. In TI website it is not recommended for new design. The original software was developed on Cygwin on Windows XP computer. The current plan is to port the software from Cygwin on Windows XP to CCS on Windows 7 computer. Would you know the latest version of CCS/CS for TMS320VC5471ZHK? or any suggestion to port the software?

Thanks,

Gansheng

    Hello,
    The latest version of CCS that supported C54x is CCSv5.5. You will have to use that version. As for porting the software, it is best to ask the experts in the C5000 forums.

    Thanks

    Hello,

    You are right"The latest version of CCS that supported C54x is CCSv5.5".

    The difficulty for me is in porting code for ARM7TDMI in TMS320VC5471ZHK. TMS470R1x also has ARM7TDMI. TMS470R1x is different from TMS470MF*****, which has ARM cortex-M3. So my question is :what is the latest version CCS to support ARM7TDMI, such as TMS470R1x?

    Thank you,

    Gansheng

    Current versions of CCS (7.x.) still support ARM7. But since current versions of CCS does not support C54x, you may want to use CCSv5.5 for both ARM7 and C54x

    TMS320VC5471ZHK has ARM7TDMI. It is belong to ARMV4T, and it is little different from ARM contrex-M3,which is like TMS470MF******. If porting code from ARM7TDMI to ARM contrex-M3, there are some work need to do(There are some online documents introduced the difference, and how to porting).

    Up to CCS Version 7, I saw it support TMS470MF******, but I did not see it support ARM7TDMI, such as TMS470R1x. What I have earlier CCS version 4,but I did not see it support ARM7TDMI. In CCS 7, I also did not see device selection for TMS470R1x, but only TMS470MF******. Please correct me if I miss understand something.

    CCSv7 does support TMS470R1x. However, you may need to create a custom configuration to use it:

    I recommend posting in the C5000 forum for recommendations on which CCS version would be best for your device. They will have the best recommendations.


    Thanks
