I asked: > 3) What checksum do you get when you assemble the project?

That is a definite problem. That's why I said it is very important to post the checksum you are getting. Looking into other reasons is pointless until you get the 0xF671 checksum when you assemble the project. When I get a chance, I'll check out your code to see why you are not getting the correct checksum. Also, did you try the HEX file I sent you?
