Steve,

Thanks for taking a look. Hopefully you didn't look at the hex_output.txt file as a hex file... it is an ASCII file of the hex values as text.

I converted the object file to Intel HEX, but still the ORG was wrong. It seems the assembler adds a lot of extra 'stuff' to the OBJ file (filename etc.) that I don't quite understand yet.

I opened a support case with Tasking so hopefully they can point me in the right direction.

Hans,
I think that you only need the leading zero if the value has a non-numeric as the first character of the address. So 1a0h is OK, but you would need a zero if it was a1a0h.

Thanks guys
John K.
