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 + +The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It +features a 7-stage pipeline, 16KB instruction and data caches and a full +Memory Management Unit. It also comes with a large set of integrated +peripherals, many of which are shared with the AT91 ARM-based controllers from +Atmel. + +Full data sheet is available from + +http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf + +while the CPU core implementation including caches and MMU is documented by +the AVR32 AP Technical Reference, available from + +http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf + +Information about the AT32STK1000 development board can be found at + +http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918 + +including a BSP CD image with an earlier version of this patch, development +tools (binaries and source/patches) and a root filesystem image suitable for +booting from SD card. + +Alternatively, there's a preliminary "getting started" guide available at +http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links +to the sources and patches you will need in order to set up a cross-compiling +environment for avr32-linux. + +This patch, as well as the other patches included with the BSP and the +toolchain patches, is actively supported by Atmel Corporation. +
