Linux port now on ARM9 core-based microcontroller

19 November 2003 DSP, Micros & Memory

Atmel has launched a Linux operating system port for its AT91RM9200 microcontroller and its ARM9 core-based ASICs. It enables application developers to take full advantage of the resources and support from the growing worldwide Linux community. The AT91RM9200 development kit (AT91RM9200-DK) with Linux support is available now with a ready-to-use Linux development environment.

The AT91RM9200 Linux port consists of the industry-standard Linux V2.4.19 kernel, the ARM9 Linux adaptation maintained by the ARM Linux support team, and a set of AT91RM9200 Linux code modules that comprise the peripheral drivers and a kernel patch for the AT91RM9200-specific features (advanced interrupt controller and system timer). It includes a minimal RAM disk that contains the most frequently used commands. These elements are available as both source code (C and assembler) and as compiled binary objects. They may be obtained from the Atmel website ( www.atmel.com), or downloaded from the SourceForge website ( www.sourceforge.net)

The standard AT91RM9200-DK is supplied with all the software tools a developer needs on CD-ROM. In addition to the AT91RM9200 Linux port, this CD-ROM has the open-source GNU toolchain (in source and compiled versions) including a C compiler, GLIBC library and utilities, as well as the U-Boot loader utility. A comprehensive include file defines all the register names, fields and offsets in the AT91RM9200 architecture. It forms the basis of the AT91RM9200 Linux port and is also intended for use in any applications running on the AT91RM9200.
