VS2013 Debugging issue

we are using Toradex Colibri VF61, and when deploy our code for debugging, its not hitting the break points in the Visual Studio 2013, the break points disabled by an error message “The break point will not currently be hit. no symbols have been loaded for this document”. and we have another set of boards where it works perfectly and we use same location in the colibri to deploy the code

Is that “another set of boards” Colibri VF61 as well? Could you please share the BSP version you are using?
