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.
