I have never debug that but you have to ensure that you can use console at that time. I would say that MIO setting for console has to be done. Or you have second option which I haven't tried which is to use DCC port where I believe you don't need to setup any MIO pin. Thanks, Michal --- Michal Simek, Ing.
