Hi Deven,

Cool :)

Since the AVR32 port was added that have not been a full release.
Therefore, you can only find it on the SVN right now. I guess maybe in
one beta if one is out, I haven't checked.

> Now, here are a few Qs:

As far as I tested with the examples, it was working pretty good. I
think the serial port driver could use more testing, and there are a
few drivers missing. Also the SPI driver still needs testing as well.

Probably it will be in the next release, but you could try it out
using the SVN code before that. Actually the more help testing the
better *smile*.

I still don't have my custom hardware, but I received recently the
EVK1105 and an AVRONE to continue my work on the port. Up until now I
have only tested with the ES version, but I did try to keep up with
the differencese, so that the code works with both ES and non-ES. The
new kit will be the first test with non-ES version AFAIK. I've been a
bit busy with an AP7000 project, but will get back to the UC3 port as
soon as possible.
