SheevaPlug mini 'pluggable' computer
Finally I can get my hands on a SheevaPlug, the best replacement for my Linksys NSLU2 as plug computer.
Today digital home services such as media servers, file sharing and backup software all need to be installed on a PC.
A plug computer is a small, powerful computer that connects to an existing network using Gigabit Ethernet.
This type of device eliminates the need for an always-on PC in the digital home to access these services.
The shipment from Globalscale took 3 weeks that is quite too much especially considering that they charged my credit card the day I ordered it, but anyway now I can start hacking it.
- Crossover LAN cable
- USB Cable
- Power supply cable (American plug)
In order to connect it to a host PC you have to plug in the USB connector and manually load the appropriate USB device driver on host PC
sudo modprobe ftdi_sio vendor=0x9e88 product=0x9e8f
then unplug the USB connector, launch minicom on /dev/ttyUSB1 and plug in SheevaPlug again...

The platform is built using Marvell’s Kirkwood series system-on-chip (SoC) design with a 1.2GHz Marvell Sheeva™ CPU processor equipped, 512Mbytes of FLASH and 512Mbytes of DRAM. The plug also features a 2.0 USB port to allow users to run applications that require a hard disk or other peripheral.
You can find more detils on Marvell website.
Designed from the ground up to simplify the management of digital media assets, the Marvell plug computer is designed to be left plugged into a wall socket at all times. The plug uses low power to conserve energy and draws on average, less than five watts under normal operation compared to 25-100 watts for a PC being used as a home server.
