Debian on Smartphones/Tablets

Please add some valuable information to help this project move forward. :)

This page is about tracking every initiative to fully or partially install the system on mobile platforms:

About

Debian is the universal operating system. Thus, it needs to run on smartphone/tablet hardware. This wiki page is a tool to help bring Debian to mobile platforms.

It would be great if Debian could run on many kinds of smartphone hardware: iPhones, Android capable HW, Windows Mobile HW, etc.

The software should allow dual booting, into both Debian and any software that came with the hardware.

Debian on smartphones should have GUI capabilities, appropriate to the hardware capabilities.

It would also be great if Debian could run applications written to be native to the original OS for the hardware. This will enable Debian to serve the many people in society who want to easily use those applications.

Debian might benefit from having its own User Interface, or UIs, based on progression from the desktop Debian UIs - ex, GNOME or KDE. It would be great if the GNOME, KDE and other GUI communities could come to agreement on a common UI for Debian, to save unnecessary duplication of development effort, both of the Debian UI, and application software for Debian. Also to save the users from having to learn unnecessary extra UIs.

Origin and Purpose

To get this wiki page started, see the original message I sent suggesting this project. It includes some reference URLs, to help seed thinking on Debian on smartphones development.

Contributions

Many people made useful replies to that email, and it would be great if they would add their suggestions of software components, foundations, and URLs thereof to this page. If we all take a few minutes to make contributions to this page when we have something valuable to add, this page will grow to be a great resource for us all. So, please take a moment to add something valuable to this page right now, or when you have the opportunity. :)

This page could use contributions like: Links to component software (embeded debian, GRUB, UIs, etc).

Software developers can write software for the many parts of this system and put links on this page to those components.

Writers can produce articles about Debian on smartphones in emails to the relevant Debian mailing lists, blogs, web pages and for the general media.

Artists can create the graphics and multimedia for Debian on smartphones.

Packagers can put it all together so people can download and install it on their smartphones.

Thanks for reading. Thanks for thinking. Thanks for all contributions you make. Let's all work together to enable Debian to fulfil its promise as "The Universal Operating System". :)

Contact

To chat about Debian on mobile devices, please join the #debian-mobile IRC channel on irc.debian.org.

other discussions will be appropriate to have on the following lists instead:

Howto

General

Learn software development.

Port low-level stuff to a device.

Package some middleware.

Package a user experience.

Package applications that can deal with small screens and touch input.

Build images for users to flash onto the device.

Get hardware to developers.

Learning

At various stages you will need to learn some of the following. This can be done at the same time as working on Debian for smartphones.

Porting

Pick a specific device. Get support for it into a bootloader (u-boot/etc), mainline Linux. Ask relevant teams to build linux/bootloader packages that work on your device. Port the debian installer to the device.

This is most of the work. It is important to get your changes into Linux/u-boot mainline otherwise Debian will not be able to support your device since the Linux kernel team for Debian will not add non-mainline drivers/patches to Debian kernels and therefore you won't be able to support Debian on the phone you care about. It will be made easier since the Android drivers probably already exist and can be ported to mainline Linux. Some hardware vendors will be violating the GPL and not releasing drivers/patches. You might be able to get the code by contacting them or getting the SFLC or gplviolations.org involved.

Middleware

Pick some middleware, join the packaging group for it or package it for Debian and look for some sponsors.

Existing middleware includes FSO (in Debian), oFono (in Debian), pyNeo, Android/MeeGo/Maemo.

UI

Pick a UI or create a new one, create a team, start packaging it for Debian and look for sponsors.

There are numerous existing FLOSS UXen for smartphones and similar devices. As the universal OS, Debian should aim to support several of these.

Applications

Start an index of touch-screen friendly apps and package some of them. Most of them will be ?OpenMoko ones since that was the first free software friendly phone. So read their wiki and related sites a lot.

Images

Talk to the Debian installer, live and CDs teams about building daily, weekly and release images that people can flash onto their phones. This could significantly change the way Debian images are built so it will require a fair bit of discussion first.

Other tips

If you can get hardware into the hands of kernel developers that would help a lot. You might find some hardware manufacturers who are willing to give out some free samples to developers.

Apparently, Ubuntu can run natively on a Nexus S. Maybe we can learn from this effort and port debian natively to multiple devices:

Many of the smartphone tasks are handled by the FreeSmartphone.Org (FSO) team:

Openmoko's FreeRunner is so far the device best supported:

Nokia's Maemo is based on Debian:

Also there is an ugly alternative to install Debian is to run it in a chroot dir:
