The wiki only describes combining IMG files together, whereas you  
appear to be both combining IMG files whilst also processing OSM  
files, in the same step.  Like I said before, I'd recommend you do all  
the OSM processing first.  Then combine IMG files in a second,  
separate step.  I'm not saying that you can't do it any other way,  
just that this way works!
