    Hi Abhiram,

    Please follow the steps below:

    1. In your target config .ccxml file (software-dl.ti.com/.../CCS_SETUP_PAGE.html, when launched, will show you multiple core options:

    2. Connect to the required cores (core0 and core1), and load the .out file individually.

    If you are using a systems project, then you can just start a debug session on systems project and it will automatically load the files for 2 cores. incase you have two individual projects, you will have to load manually.

    The debugging process is same as single-core debug.

    The above is just for debugging, loading .out to RAM and running from CCS,

    Incase you want to create a .mcelf appimage and flash the binary to the Flash memory, you will have to create a systems project (multi-core project) and then create a .mcelf file which has combined codes from both cores, then flash that using UniFlash tool or the python scripts.

    For reference on creating system project, you can follow this guide: Creating system projects

    For understanding mcelf and using it:Flashing tools
