Re: [AVaRICE-user] Various patches to AVaRICE

Hi Martin & Michael,

> we have implemented a few patches concerning AVaRICE.

Thank you very much for your work!

As I already told you in private mail, please submit all patches
through SourceForge's patch tracker system.  Patches submitted to
mailinglists have a tendency to eventually get lost.

(If you don't subscribe to the list, you might miss replies if there
are any.)

OK, I've deprecated the target programming feature (AVRDUDE is the
main tool for that purpose, and maintaining partially duplicated code
inside AVaRICE is just a nightmare), but if the change is simple
enough, I'll incorporate it.

Sounds interesting!

Fair enough.

It would be interesting to extend this to the JTAGICE3 tool, and then,
eventually, to the new Atmel-ICE (ARM + AVR common debugging tool,
quite low-priced compared to existing Atmel tools).

The latter is not yet done in AVaRICE (only AVRDUDE so far), but I'll
certainly implement this so-called EDBG protocol sooner or later.  As
it is primarily a wrapper around the older (firmware version 2.x)
JTAGICE3 protocol, everything that works with the JTAGICE3 will then
automatically also work for the Atmel-ICE.

But not that of Atmel Studio, I think ...  AVR Studio is discontinued
anyway.  So this might give AVaRICE an advantage.
