Core2 not working with COMMU Module

[daniel3344]

Hi!
I am trying to get the COMMU module working with the Core2. I am not able to upload anything to the Core2 when the COMMU module is attached. If I remove the module the Core2 works ok.

What is needed in order to get this working? Should I move/re-solder the J6, J7, J9, J10 numbers on the board as described vaguely in the doc? Is it something more that is needed? GPIO changes?
