avrstudio:
You are not forced to use AVR Studio (the IDE).

You are forced to extract the include files from AVR Studio, because license
obligations do not permit anyone else to distribute those files, or
AVR Studio itself.

You are not forced to use the AVRAssembler2 that comes with AVR Studio.
You can do with avra. However, that means
a. you either stick to older controllers, where all files from Atmel come
    in the Assembler Version 1 format,
b. or you need to patch the newest avra (1.3.0) with patches contributed by
    M.Cieslak. These patches have not been included in avra for reasons I
    don't know. I have built a patched version of avra and use it routinely.
    "Works for me (tm)".

Help to get avra in shape to completely support Version 2 of Atmels
assembly format would be highly appreciated!


Linux or Windows:
For me working with amforth is a Linux activity, with occasional excursions
into wine+AVRStudio|AVRAssembler2 land, mainly to see, if using the windows stuff
changes anything if on a bug hunt. And btw, I'm running wine on a amd64 system.


Editing text files:
There is *no* way around this.
You absolutely must configure the amforth system for your values of
. exact controller
. exact crystal frequency
. exact fuse settings
. exact baud rate
. exact settings of your programming dongle
These are the absolutely required minimum. And no, I don't want the
amforth system to take any guesses. But this is not everything.
I routinely include a number of words via dict_appl.inc. Again,
amforth provides the minimum to run, but I want more, and that "more"
is certainly different from your version of "more".

I routinely use a much larger Makefile, just due to the way I choose
to work. And so on.


My reasoning may be inaccurate, your milage may vary ...

Hope that helps, have a nice day.
Erich
