I knew that I show something relating to this on Metrowerks's Online
Support, so I copied this the last time I surfed Online Support: Adapt the
HC(S)12 response for the HC(S)08. BTW, I didn't notice an item 3) in the
response...

FAQ: Can CW HC12 be used as a stand alone flash programmer for the HC(S)12
mcu?

Answer: Yes, it is possible. To do that you should:
1) Get a licensed CW HC12 install for flash programming, free SE license
will work.
2) Copy project.ini from your project into CW HC12 install\prog, check if
"LoadDialogOptions=CODEONLY" appears under the [HI-WAVE] section. If not,
add it.
4) Copy your *.s19 from your project\bin into CW HC12 install\prog as
MyProject.s19.
5) Go to C:\program files\metrowerks\CodeWarrior CW12_V2.0\prog in DOS
window and run "hiwave.exe -Prod=project.ini MyProject.s19". The s-record
will be loaded into mcu automatically. You can build a DOS batch file as
following and let operator just click this ProgramHCS12.bat -- "c:\program
files\metrowerks\CodeWarrior CW12_V2.0\prog\hiwave.exe" -Prod=project.ini
MyProject.s19 You can also change the path of your CodeWarrior installation
accordingly. Also change the s-record name to the one you want.
