Re: separate flash space problem -- solved

Hi!

     I usually use another way to put the codes into the upper 64KB area of
ATMega128.(need new compiler
words to support their execution, but it is not concerned in this problem).
The codes can be correctly saved
into TARGET.HEX. My SWiftX version is 2.04.2A. Not sure if it will work on
other versions.

     $12000 EQU TopCode
     ....
     THERE ( --adr) TopCode OVER - GAP
      : boot 12 . ; \ put the codes into the upper 64KB
     THERE EQU TopCode \ save it for next time usage
     ( --adr) THERE - GAP \ restore the pointer in lower 64KB

     Best Regards,

     Jach Fong
