AVR32 is a new from scratch 32bit MCU more akin to Atmel's ARM product
line. Most of the peripheral IP comes from the ARM family and not the
existing AVR family. (I haven't checked though) I think the products
are closer to a Blackfin DSP in terms of performance and memory.<br>

<pre wrap=""><!---->It may be a different instruction set but I don't see avr vs avr32
in config.gcc. There is only avr-:
The RTEMS AVR tools build the following multilibs:
$ /opt/rtems-4.9/bin/avr-rtems4.9-gcc --print-multi-lib
.;
avr3;@mmcu=avr3
avr4;@mmcu=avr4
avr5;@mmcu=avr5
But the gcc info description of those cpu differences don't sound
like avr32:
Instruction set avr3 is for the classic AVR core with up to 128K
program memory space (MCU types: atmega103, atmega603, at43usb320,
at76c711).
Instruction set avr4 is for the enhanced AVR core with up to 8K
program memory space (MCU types: atmega8, atmega83, atmega85).
Instruction set avr5 is for the enhanced AVR core with up to 128K
program memory space (MCU types: atmega16, atmega161, atmega163,
atmega32, atmega323, atmega64, atmega128, at43usb355, at94k).
The base avr and avr2 will be hard to get RTEMS into since avr2 has up to
8K program space. But avr3-5 would be OK but wouldn't run all tests and
couldn't support the RTEMS TCP/IP stack.
