What ARM single-board computers does are supported by Ubuntu?

Solution 1:

The little MK802 devices have an ARM-cored Allwinner A10 which runs Ubuntu/Lubuntu absolutely fine. Google MK802 Lubuntu to find OS images for it: google MK802 Mini PC to find the devices (~ $75). These are more powerful than the Raspberry- approx 1.5GHz CPU and 1GB of RAM.

Solution 2:

Looks like the answer is no. Look at this entry in the Raspberry Pi FAQ:

What Linux distros will be supported at launch? Debian, Fedora and ArchLinux will be supported from the start. We hope to see support from other distros later. We will be selling SD cards with the distros preloaded. (Sept 4 2011 – originally, this FAQ suggested that Ubuntu would be supported. Because of issues with newer releases of Ubuntu and the ARM processor we are using, Ubuntu can’t commit to support Raspberry Pi at the moment.)

Debian will be supported, though, so it will look familiar :)

BeagleBoard

The BeagleBoard measures approximately 75 by 75 mm and has all the functionality of a basic computer. The OMAP3530 includes an ARM Cortex-A8 CPU, a TMS320C64x+ DSP for accelerated video and audio decoding, and an Imagination Technologies PowerVR SGX530 GPU to provide accelerated 2D and 3D rendering that supports OpenGL ES 2.0. Video out is provided through separate S-Video and HDMI connections. A single SD/MMC card slot supporting SDIO, a USB On-The-Go port, an RS-232 serial connection, a JTAG connection, and two stereo 3.5 mm jacks for audio in/out are provided.

Built-in storage and memory are provided through a PoP chip that includes 256 MB of NAND flash memory and 256 MB of RAM (128 MB on earlier models).

The board uses up to 2 W of power and can be powered from the USB connector, or a separate 5 V power supply. Because of the low power consumption, no additional cooling or heat sinks are required.

Solution 4:

Ubuntu currently has no plans to support older ARM architectures than ARMv7. Limited support for earlier instruction sets (ARMv5t, ARMv6) was available in early releases of the Ubuntu ARM port (jaunty, karmic).

RaspberryPI is ARMv6-based. For support on older ARM architectures, I suggest you use Debian.
