Yes, all AT91 ARM9s support booting from SPI but the
bootROM is evolving with new parts.

Ulf,
you are absolutely correct, I described the 9261 when I was talking
about the 9260 and vice versa.
Haven't heard about the 9263 yet. Sounds good except for the package
BGA 324?
Also, is the build in support for booting from serial, I guess SPI
Flash?

Please try to keep your line lengths under 72. 65 is better.

I think that if you have read Atmels public statements on the AVR32 you will
find that
the AVR32 is designed to be a general purpose controller with media
functionality.
Some of the media functionality is in the instruction set and some is in a
coprocessor
(which might or might not be present in any new chip).
The AVR32 is basically available to all groups within Atmel that want to use
the core,
and when it is time to release information about new chips, I am sure there
will be a formal press release.

It has basically the same peripherals as the AT91SAM9 series, which are
considered to be general purpose controllers.
If it happens to have the right match of peripheral, then you need to
compare the price with other parts
with sufficient functionality.
If it then has the lowest price, you go for it, otherwise you go for
something else.
Some key things which are not (yet) present in AT91:
Combined Ethernet + LCD control
USB High Speed client.
AC-97
DMA
The NEXUS Calls 3+ debug is superior to the JTAG of the ARM.
If you look at support, then gcc and linux + file system is directly
supported by Atmel for the AVR32.
For the AT91, you can either go to maxim.org.za/AT91RM9200/2.6 or to
Timesys.
There are AT91 features which are not matched by the AP7000 chips.
The new AT91SAM9260, (just got my first samples and dev boards shipping this
week :-) will surely be lower cost than any of the AP7000 chips.
The SAM9261 has a huge SRAM.
The boot ROM is getting better and better (most of my request for new
functionality was introduced in the SAM9260 bootROM)
- no bootROM in the AP7000 so I am pestering the guys constantly!!
In the end some will select ARM because they want ARM and other will go for
best chip to meet their needs
and then the AVR32 can compete.
One of the nice advantage of the Atmel Norway design centre is that they are
hungry
and are open to any idea that will improve their offering.
They are not afraid to acknowledge weaknesses (internally), and will put a
lot of effort into fixing stuff.
Just look at the Picopower. Think they derve a lot of credit for that
development.

The mega103 started life as a custom chip and now it's spawned the
mega2560, which is really useful, apart from the rather clunky RAMPZ
paging register. Just wait a few years and see where the AVR32 goes. Of
course, by the time it get to be useful, I'll probably be far too old
to be able to make sense of it >:-}

Yes, but the AVR32 doesn't seem to be a 32 bit version of the 8 bit AVR
we all know and love, it's seems to be some type of customized chip
made for a large customer now offered to the public.

Are you going to make an AVR32 MCU with flash?
Right now it looks like a specialized media chip, rather than a general
purpose controller.

Now when we have the AVR32, this comment may be confusing :-)
It will still be an ARM7.
