Oh, you meant the other one :-) That one has a type of 04 which means it's not a data record, but an "extended address record". This is to account for 32 bit addresses; in your case it just says the upper address bits (think 'banking') are zero. So your recourse is to ignore (or interpret) that record. Been there, wrote a bootloader, had the same problem. And as Tony says, this is an extension added for hex-32. And maybe the hex-8 format won't have anything like this. It should be happy on a 14-bit part, anyway. Barry -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics
