1AVR32 is a new high-performance 32-bit RISC microprocessor core, 2designed for cost-sensitive embedded applications, with particular 3emphasis on low power consumption and high code density. The AVR32 4architecture is not binary compatible with earlier 8-bit AVR 5architectures. 6 7The AVR32 architecture, including the instruction set, is described 8by the AVR32 Architecture Manual, available from 9 10http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf 11 12A GNU toolchain with support for AVR32, along with non-GNU programming 13and debugging support, can be downloaded from 14 15http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4118 16 17A full set of u-boot, kernel and filesystem images can be built using 18buildroot. This will also produce a working toolchain which can be 19used instead of the official GNU toolchain above. A customized version 20of buildroot for AVR32 can be downloaded here: 21 22http://www.atmel.no/buildroot/ 23 24The AVR32 ports of u-boot, the Linux kernel, the GNU toolchain and 25other associated software are actively supported by Atmel Corporation. 26
