    Hi,

    Here is the wiki how to setup a hello world example for ARM & DSP cores:
    software-dl.ti.com/.../Examples_and_Demonstrations.html

    And here is a link for the multi core debug steps:
    processors.wiki.ti.com/.../Multi-Core_Debug_with_CCS

    Best Regards,
    Yordan

    Hi,
    I followed your instructions to create a "hello world" project
    * I'm using CCS 7.4.0 & processor_sdk_rtos_c667x_4_03_00_05.
    * I also modified 2 code lines in: C:\ti\pdk_c667x_2_0_9\packages\pdkProjectCreate.bat
    # 70 : set SOC=C6678 (it was a57..)
    #124 : set PROCESSOR=dsp (it was arm)

    *** Configuration:
    Blackhawk XDS560v2-USB Mezzanine Emulator
    TMS320c6678

    *** The build generates the following warnings:

    Hi,

    Ok, so this is indicates that you don't have a correct linker .cmd file. You're probably running a custom project and not some of the projects included in Processor SDK RTOS, right?

    You can get there through: Project/Properties/General. *.cmd files are situated in: ~/ti/ccsv7/ccs_base/c6000/include


    Best Regards,
    Yordan
