Re: [avrdude-dev] XMEGA32A4U not supported?

[Axelrod, Benjamin]

Interesting.  I can potentially program a XMEGA32A4U from Atmel Studio 6.1 with 
both an AVRISP mark 2 and AVR JTAGICE3.  However, I recently noticed that Atmel 
Studio doesn't have support for fuse0 on the XMEGA32A4U part, which is part of 
my reasons for looking into this.  The other issue is that my windows box is on 
a virtual machine which I believe is preventing me from updating the firmware 
on my AVR JTAGICE3, and thus preventing me from actually using it with Atmel 
Studio.

(I am currently talking with our Atmel contact about the fuse issue.  No word 
back yet).

I believe these (and the A3Us) use a slightly updated JTAG ICE protocol, which 
avrdude does not currently support. I had promised Joerg Wunsch to send him 
some traces from Atmel Studio programming these new chips, but haven't gotten 
around to it. If you have the capability to program these with Atmel Studio and 
get USB traces, these may be useful to Jeorg to add support for these.

There is also another way, using DFU functionality. There is an experimental 
patch to do this:

But this also needs testing.
