OpenMoko

Openmoko is a project to create a family of open source mobile phones, including the hardware specification and the operating system.[1] The project was sponsored by Openmoko Inc.

The first sub-project is OpenMoko Linux, a Linux-based operating system designed for mobile phones, built using free software.

The second sub-project is the development of hardware devices on which OpenMoko Linux runs. The first device released was the Neo1973,[2][3] which was followed up by the Neo FreeRunner on 25 June 2008.[4] Unlike most other mobile phone platforms, these phones are designed to provide end users with the ability to modify the operating system and software stack. Other Openmoko-supported phones are also available.

On 2 April 2009, OpenMoko canceled planned phones and will probably concentrate on other kinds of hardware,[5] but will still support and sell the current Neo FreeRunner.[6]

Hardware

FIC Neo1973

The FIC Neo1973 (GTA01) was the first cell phone shipping with a completly open stack. It served as the OpenMoko GTA01 reference platform. This is important for IP storage over cellular networks, as described in GSM.

The prototype has been tested by running Core-iSCSI connected to a PS3 over 802.11b/g WiFi and GPRS using a small (2GB) ext3 READ-ONLY mount. So far, audio playback using OpenMoko Media Player across WiFi is stable.

Neo FreeRunner

The Neo FreeRunner (GTA02) succeeded the Neo1973. The software reference stack we built for it contains Core-iSCSI+OCFS2 on the client side, and LIO+DRBD on the server side (Downloads).

Download: Initiator Core-iSCSI v1.6.2.11.

Software

Setup

Installation of the modules: 

ipkg install <module_name>.ipk

After installing the *modules* .ipk, so modprobe will pickup the new modules: 

depmod -ae

Devices

The OpenMoko shows the iSCSI device as follows:

Documentation

GSM provides more information specific to iSCSI over cellular networks, Core-iSCSI provides more information on the initiator, LIO contains locating distribution support and how to build from source.

LIO-VM describes how to quickly setup an iSCSI target by using a virtual machine. This works particularly well with FILEIO, USB, and generic SCSI backstore export, e.g. with VMware Workstation for Linux, MacIntosh and Windows.
