    If you don't want prints from M3s then you can add

    killall remote_debug_client.out 2> /dev/null

    at the end of load.sh script file

    There is no support for printing msgs from only one core. You can modify

    /dvr_rdk/mcfw/src_linux/utils/remote_debug_client/src/remote_debug_client.c

    int RemoteDebug_clientRun(unsigned int coreObjPhysBaseAddr)

        for(coreId=0; coreId<REMOTE_DEBUG_CORE_ID_MAX; coreId++)

            do {
            numBytes = RemoteDebug_clientGetLine( coreId, gRemoteDebug_clientObj.lineBuf );
            if(numBytes>0)
            {
                if (coreId != <SKIP_CORE_ID>)
                {
                    printf(" %s %s\n", gRemoteDebug_corePrefix[coreId], gRemoteDebug_clientObj.lineBuf );
                    /* Set for line buffering so that even if output is piped buffering does not happen */
                    fflush(stdout);
                }
                doWait = 0;
            }
            }
        while(numBytes);
