Each distinct ARM architecture requires its own kernel. Because of this the standard Debian distribution only supports installation on a number of the most common platforms. The Debian userland however may be used by any ARM CPU. Most ARM CPUs may be run in either endian mode (big or little). However, the majority of current system implementation uses little-endian mode. Debian currently only supports little-endian ARM systems. The supported platforms are: IOP32x Intel's I/O Processor (IOP) line is found in a number of products related to data storage and processing. Debian currently supports the IOP32x platform, featuring the IOP 80219 and 32x chips commonly found in Network Attached Storage (NAS) devices. Debian explicitly supports two such devices: the GLAN Tank from IO-Data and the Thecus N2100. IXP4xx The IXP4xx platform is based on Intel's XScale ARM core. Currently, only one IXP4xx based system is supported, the Linksys NSLU2. The Linksys NSLU2 (Network Storage Link for USB 2.0 Disk Drives) is a small device which allows you to easily provide storage via the network. It comes with an Ethernet connection and two USB ports to which hard drives can be connected. There is an external site with installation instructions. Kirkwood Kirkwood is a system on a chip (SoC) from Marvell that integrates an ARM CPU, Ethernet, SATA, USB, and other functionality in one chip. We currently support the following Kirkwood based devices: SheevaPlug and QNAP Turbo Station (TS-119 and TS-219). Orion5x Orion is a system on a chip (SoC) from Marvell that integrates an ARM CPU, Ethernet, SATA, USB, and other functionality in one chip. There are many Network Attached Storage (NAS) devices on the market that are based on an Orion chip. We currently support the following Orion based devices: Buffalo Kurobox, HP mv2120, QNAP Turbo Station (TS-109, TS-209 and TS-409). Versatile The Versatile platform is emulated by QEMU and is therefore a nice way to test and run Debian on ARM if you don't have the hardware.
