Probably Linux Devices news feeds on my site should be updated to something more up-to-date…

ArchLinux ARM supports plug-computers, home NAS appliances and community ARM Cortex-A8 , Cortex-A9 development boards from known chip vendors:

ARMv5: SheevaPlug, TonidoPlug, PogoPlug v2, PogoPlug Series 4, Seagate DockStar/GoFlex ; ARMv6: PogoPlug Pro/v3 ; ARMv7: Gumstix Overo, BeagleBoard TI OMAP 3530, BeagleBoard-xM TI DM3730, PandaBoard TI OMAP 4430, TrimSlice NVIDIA Tegra 2

ArchLinux has a special site dedicated to ARM architecture support: http://archlinuxarm.org/

Latest ARMv5 snapshot (around 138MB) can be taken from here:

Buildroot-2011.xx with sheevaplug_defconfig gives a fast way of making uImage with embedded initramfs and some busybox packages. After loading Buildroot’s uImage with tftpboot method in u-boot, one can mount a partition on built-in SATA drive (/dev/sda1), remove Marvell’s NAS software, download and untar ArchLinuxARM tarball.

After successful boot into ArchLinux, let’s verify that package management works:
