OpenMP Hello World template project stuck when loading using debug button.

I am trying to run the template OpenMP "Hello World" project, according to the directions here:

http://processors.wiki.ti.com/index.php/OpenMP_on_C6000

Per the directions, the only modification I made to the template project is the following line added to the .cfg file:

OpenMP.autoDnldCore = false;

The project builds without issues. When I click the debug button, it proceeds to load the .out file onto the individual cores. Core 1 loads first (and without issue), but when it gets to core 2 it gets stuck. I eventually have to kill Code Composer through the task manager. Below is a screenshot of where it gets stuck.

I can get the project to work by loading the cores manually. I disable "Run to symbol main on program load or restart" for each core. I then manually load each core with the .out file. Each core is suspended at .cinit00. I then run cores 1,2,3, then core 0. And I get the expected output. 

What is causing this?

    This is a commonly used workaround for OpenMP runs - users have to disable the 'run to symbol..' option as you mentioned.

    That said if you are setting the autoDnldCore to false it should not run into errors provided you are using a version of the OpenMP library that supports this.

    Thank you.
