AVR32 is a new high-performance 32-bit RISC microprocessor core,
designed for cost-sensitive embedded applications, with particular
emphasis on low power consumption and high code density. The AVR32
architecture is not binary compatible with earlier 8-bit AVR
architectures.
The AVR32 architecture, including the instruction set, is described
by the AVR32 Architecture Manual, available from
http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf
A GNU toolchain with support for AVR32, along with non-GNU programming
and debugging support, can be downloaded from
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4118
A full set of u-boot, kernel and filesystem images can be built using
buildroot. This will also produce a working toolchain which can be
used instead of the official GNU toolchain above. A customized version
of buildroot for AVR32 can be downloaded here:
http://www.atmel.no/buildroot/
The AVR32 ports of u-boot, the Linux kernel, the GNU toolchain and
other associated software are actively supported by Atmel Corporation.
