C6672 network drivers

David Hand
Intellectual 885 points

I'm looking at using the C6672 DSP but I'm not sure where to find the necessary drivers. I have the C6670 EVM and there is a PDK for it. I also see one for the C6678. But none for the C6672.

Where would I find the necessary drivers and support libraries for the C6672? Can I use the C6678 drivers assuming I use the same Ethernet Phy?

    David,

    You can find the similar group of multicore DSPs at:
    http://processors.wiki.ti.com/index.php/Keystone_Device_Architecture

    Yes, the bios-mcsdk supports selected devices/platforms only. More details get from the user guide.


    BIOS-MCSDK Download Link:
    http://software-dl.ti.com/sdoemb/sdoemb_public_sw/bios_mcsdk/latest/index_FDS.html
    Go through the wiki pages, which are supported device/platforms for BIOS-MCSDK
    http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide#Supported_Devices.2FPlatforms
    http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_Getting_Started_Guide

    Even though, you can find some of the NDK release supports C66xx devices, get detailed info from release notes. Find the NDK Download Link:

    The NDK based test code available in the MCSDK will support for C6678 EVM. If you are taking this code, you might be modify the code(Ex: EVM init, platform calls) according to C6672 device.

    Hi,

    Yes. You shall use the drivers and libraries of C6678. 

    'Please use the latest MCSDK 2.x released for keystone I devices. Please find the download and user guide link below signature.

    Thank you.

    Rajasekaran,

    If I understand correctly, the DSP cores in the C6672 are the same as the cores in the C6678; they only differ in how many cores each contains. So a driver that works for say core0 of a C6678 will also work for core0 of a C6672?

    Thanks,
    Dave

    Yes, Your understanding is correct. The network driver should work on core0 of C6672 like C6678

    Pubesh,

    Thanks for the info. I guess I should have ordered the C6678 EVM instead of the C6670.

    I see someone already marked it as answered.

    Thanks,
    Dave
