RPi Distributions

=Overview=

What is armhf
The Debian Squeeze image originally issued by the Raspberry Pi foundation as the recommended distribution used "soft float" settings. The foundation felt necessary to use the existing Debian port for less-capable ARM devices due to time and resource constraints during development of the Raspberry Pi. Therefore, it did not make use of the Pi's processor's floating point hardware - reducing the Pi's performance during floating point intensive applications - or the advanced instructions of the ARMv6 CPU.

The official Raspberry Pi distributions are now optimized for ARMv6 and for "hard float" which should have better performance on certain CPU intensive tasks.

There is some information on the news groups that "hard float" optimization can speed up floating point operating up to 10x, please read detailed discussion on the Raspberry Pi forums.

What are ARMv6 and ARMv7

Debian (Squeeze/6.x)
http://www.debian.org/ports/arm/

Debian was the default distribution on the Alpha boards. Boot time depends on width & speed of SD-card. Alpha board boot into Debian prompt (no GUI) was timed taking about 34 seconds.

The Debian distro for Raspberry Pi is the Cambridge reference filesystem, which is a fully functional Debian Squeeze installation containing LXDE (desktop) and Midori (browser); development tools; and sample code for accessing the multimedia functionality on the device.

Arch
Arch Linux ARM is based on Arch Linux, which aims for simplicity and full control to the end user. It provides a lightweight base structure that allows you to shape the system to your needs. For this reason, the Arch Linux ARM image for the Raspberry Pi does not come with a graphical user interface, though you can easily install one yourself. Please note that the Arch distribution may not be suitable for beginners.

Arch Linux ARM is on a rolling-release cycle that can be updated daily through small packages instead of huge updates every few months.

More information is available at http://archlinuxarm.org

Raspbian
Raspberry Pi + Debian = Raspbian. Initially a project to create a hard float port of Debian Wheezy (7.x) armhf for the Raspberry Pi. The intent of Raspbian is to bring to the Raspberry Pi user over 35,000 pre-built Debian packages specifically tuned for optimal performance on the Raspberry Pi hardware. The project was completed in June, 2012. However, Raspbian is still under active development with an emphasis on improving the stability and performance of as many Debian packages as possible.

For newcomers the images provided by the Raspberry Pi foundation are recommended; these are available from the Raspberry Pi Foundation's download page.

In September 2015 the Foundation released a new image based on the Debian Jessie release. This has quite a number of changes to the Debian Wheezy release.

The same image is used for the earlier Raspberry Pis (ARMv6) and the later Pi2 (ARMv7).

OpenELEC
OpenELEC is an embedded operating system built specifically to run XBMC, the Open Source entertainment media hub. The idea behind OpenELEC is to allow people to use their Home Theatre PC (HTPC) like any other device you might have attached to your TV, like a DVD player or Sky box. Instead of having to manage a full operating system, configure it and install the packages required to turn it into a hybrid media center, OpenELEC is designed to be simple to install, manage and use, making it more like running a set-top box than a full-blown computer.

RasPlex
RasPlex is an Entertainment Center Solution for Raspberry Pi Simply put, RasPlex lets you turn your TV into a Smart TV. Similar to the AppleTV, but completely free and Open Source, RasPlex is basically a set-top box software. Once RasPlex is stable, it will have support for legacy console game emulation (NES, SNES, etc), as well as Plex Channels (Netflix, Crackle, Youtube, etc). RasPlex is a Plex Home Theater Client More technically stated, RasPlex is a complete port of Plex Home Theater (formerly Plex Media Center) for Raspberry Pi. RasPlex currently runs on OpenELEC for reasons of limited manpower, but there is a working Raspbian port that just needs some time to be brought up to speed. RasPlex was created on Gentoo linux, but that port has since been abandoned for performance reasons. We regularly merge in changes from Plex Home Theater and OpenELEC. Once things cool off a bit and we are more stable (or we get the manpower), we will maintain a Raspbian release as well. RasPlex is the Perfect Companion to a Plex Media Server Many people will use expensive computers as Plex Clients, or have to go through the inconvenient of plugging a computer into their TV every time they want to use Plex. With RasPlex, just plug it in and your media is always ready. Put one on every TV, and have your media everywhere! You can even put RasPlex on your friend's TV's, and watch your media remotely.

Kali
Kali Linux Features

Kali is a complete rebuild of BackTrack Linux, adhering completely to Debian development standards. All-new infrastructure has been put in place, all tools were reviewed and packaged, and we use Git as VCS. rk3306 mk/ss808 Raspberry Pi ODROID U2/X2 Samsung Chromebook
 * More than 300 penetration testing tools: After reviewing every tool that was included in BackTrack, we eliminated a great number of tools that either did not work or had other tools available that provided similar functionality.
 * Free and always will be: Kali Linux, like its predecessor, is completely free and always will be. You will never, ever have to pay for Kali Linux.
 * Open Git source tree: We are huge proponents of Open Source software and our development tree is available for all to see and all sources are available for those who wish to tweak and rebuild packages.
 * FHS compliant: Kali has been developed to adhere to the Filesystem Hierarchy Standard, allowing all Linux users to easily locate binaries, support files, libraries, etc.
 * Wide wireless device support: We have built Kali Linux to support as many wireless devices as we possibly can, allowing it to run properly on a wide variety of hardware and making it compatible with numerous USB and other wireless devices.
 * Custom kernel patched for injection: As penetration testers, the development team often needs to do wireless assessments so our kernel has the latest injection patches included.
 * Secure development environment: The Kali Linux team is made up of a small group of trusted individuals who can only commit packages and interact with the repositories while using multiple secure protocols.
 * GPG signed packages and repos: All Kali packages are signed by each individual developer when they are built and committed and the repositories subsequently sign the packages as well.
 * Multi-language: Although pentesting tools tend to be written in English, we have ensured that Kali has true multilingual support, allowing more users to operate in their native language and locate the tools they need for the job.
 * Completely customizable: We completely understand that not everyone will agree with our design decisions so we have made it as easy as possible for our more adventurous users to customize Kali Linux to their liking, all the way down to the kernel.
 * ARMEL and ARMHF support: Since ARM-based systems are becoming more and more prevalent and inexpensive, we knew that Kali’s ARM support would need to be as robust as we could manage, resulting in working installations for both ARMEL and ARMHF systems. Kali Linux has ARM repositories integrated with the mainline distribution so tools for ARM will be updated in conjunction with the rest of the distribution. Kali is currently available for the following ARM devices:

Kali is specifically tailored to penetration testing and therefore, all documentation on this site assumes prior knowledge of the Linux operating system. Install Download If all you want to do is to install Kali on your Raspberry Pi, follow these instructions: On Windows you can use win32 disk imagier Guide how to usewin32 disk imagier
 * 1.Get a nice fast 8 GB (or more) SD card. Class 10 cards are highly recommended.
 * 2.Download the Kali Linux Raspberry Pi image from our downloads area.
 * 3.Use the dd utility to image this file to your SD card.

Alert! This process will wipe out your SD card. If you choose the wrong storage device, you will wipe out your computer's hard disk.

This process can take a while depending on your USB storage device speed and image size. Once the dd operation is complete, boot up your Rasberry Pi with the SD card plugged in. You will be able to log in to Kali (root / toor) and startx. That’s it, you’re done!

Commodore Pi
What It Is... The goal of this project is to develop a native Commodore 64 emulator and operating system for the Raspberry Pi, with the following features: •Fast boot up time - nearly instant on •Output to HDMI and composite video sources •GPIO pin connection to external devices (hooks via the kernal code) •Ethernet connection •USB Connections •Access to the full RAM of the Pi possibly via bank switching •Multitasking by means of multiple emulation cores •Modern graphics modes Think of the project as a Commodore 64 operating system. It is based on the Comeback64 emulator. The goal will be to include all of the expected emulation features such as SID sound, sprites, joystick connectivity, REU access, etc. In time, even the emulation speed could be changed, as well as additional modern graphics modes. Links Just copy to your Raspbian card. It has only been tested on composite output

PiParted
A lot of issues come from people not knowing how to do it right, e.g. just dropping the img file onto an SD card. So I’ve customised a GParted LiveCD ISO and written up a custom script to *hopefully* install a distro straight onto an SD card. This is a very early iteration of this idea, but hopefully will develop into something useful.

At the moment, essentially what it will do is


 * 1. Grab the list of Distros from the RPI Download page
 * 2. Let the user select which distro he wants to install
 * 3. Select the Disk device that he wants to install it onto
 * 4. dd the image onto the disk device.
 * 5. Flash OS from zip file on SD Card:
 * 6. Reset SD Card: This will format an SD Card back to defaults, i.e. one vfat partition.

PiBox
PiBox provides a build system based on Crosstool-NG, Buildroot/Busybox, the Linux kernel, Rasperry Pi firmware and installation tools to create a base system that can be installed to an SD card to boot a Raspberry Pi. The base system serves as a foundation on which opkg based extensions such as XBMCBox can be installed. PiBox originated as a build system and has been extended with opkgs to the media distributions. It's current focus is to provide a lightweight system for providing services (wifi webcam, media server, platform for DLP display) for travel trailers, though this is just an initial target audience.

PiBox Development Platform is the official name of the core build system. It provides the platform on which the following two products are based.

PiBox Media Server is a purpose-specific implementation built on PiBox with a goal of providing a media server that can stream webcam video and serve video files over SMB. This is accomplished by adding custom opkg installs on the base PiBox development platform. The PiBox Media Server can be used as a node on a network or as a wireless access point. Future plans include support for sensor management making it similar to a home monitoring system.

PiBox Media Player is a purpose-specific implementation built on PiBox with a goal of providing a remote media player companion to the Media Server. The player is intended to integrate with PiBox Media Server over wifi with the server acting as a wireless access point. HDMI-based DLP projectors for use as a personal Drive In Theater experience. This is also accomplished by adding custom opkg installs on the base PiBox development platform.

PiBox Media Server and PiBox Media Player are consumer oriented distributions for distributed media playback in travel trailers without Internet connectivity. The UI is based on GTK+ with Cairo and the system runs on the Raspberry Pi optimized PiBox Developement Platform distribution.

PiBox is currently a one man project. I'd like to have more users of the system and welcome new developers. To get started using the system please download the tarball, unpack it and use the mksd card to format your SD card. Then use the mkinstall script to install the distribution to the SD card. To get started with development, please read the developer wiki on how to build the PiBox Development Platform.

Contact me at mjhammel@graphics-muse.org or if you're interested in helping out, have ideas for improvement or just want to know how to use the system.

MINIBIAN
MINIBIAN is a minimal Raspbian-based Linux image for Raspberry Pi. The main focus is to have a small, updated and stable distribution that is fully compatible with official Raspbian “Wheezy” image, without GUI and unneeded tools. So this image is perfect for embedded projects, or wherever you need to use all RPi resources for your specific tasks. The main advantage is that MINIBIAN has a very small footprint, boots in some seconds and uses just few of precious RPi RAM. Unlike other similar projects, MINIBIAN has not been obtained purging unneeded packages from original image, neither recompiling the source code: it’s just a customized Raspbian installation obtained from the same repository used for official RPi Wheezy image. So kernel and binary files are exactly the same you will find on standard image, with the difference that MINIBIAN fit on 512Mb SD Card, is fastest, and more frequently updated.

Slackware ARM
Slackware ARM's primary goal is to provide (as near as possible) a full port of Slackware x86. Some packages have not been built since they are x86 only, whilst some have been added to support ARM platforms. Slackware is the longest surviving-- currently maintained-- Linux distribution available and is still the most "UNIX-like" Linux distribution out there. Slackware complies with the published Linux standards, such as the Linux File System Standard and has always considered simplicity and stability paramount. As a result, Slackware has become one of the most popular, stable, and friendly distributions available. There's a vast number of people running Slackware ARM on their RPis. Since before the release of Slackware ARM 14.0, there have been a number of community efforts to bring Slackware to the Raspberry Pi. From preinstalled images to full installation guides, Slackware ARM has a thriving community of Raspberry Pi users, and is very well supported in that respect. Slackware has always been well known for its reliability, power, and versatility, and that's exactly what you will find when running it on the Raspberry Pi. The Slackware-on-Raspberry Pi community caters for all the original RPi versions as well as the latest Raspberry Pi 3 model B. Slackware ARM hard float port is now available for the Raspberry Pi 2 and Raspberry Pi 3.

Slackware ARM is not supported by the Raspberry Pi Foundation. The Raspberry Pi is only supported by the Slackware community, outside of the official Slackware ARM tree.

Ubuntu was initially planned to be the default distribution, but the current version of Ubuntu only supports ARMv7 onwards, not the ARMv6 architecture used by the Raspberry Pi's processor (until Pi 2). Therefore Ubuntu does not work on Raspberry Pi 1, and there is no further information about this changing in the near future.

A bug report on this subject was submitted to Ubuntu's bug tracker. The responses to that bug include an unofficial viewpoint from a Canonical employee, outlining the amount of work required to support ARMv6 (and therefore, potentially, Raspberry Pi 1). See Bug 848154

OpenSuSE
https://en.opensuse.org/Portal:ARM

An ARM port of OpenSuSE has existed for several years. Since July 2012 it been available as well for the Raspberry Pi.

The status is currently beta. The OpenSuSE RPi image is minimalistic, without YaST. Installation of required and optional software and performing updates are quite simple with zypper, the same as on x86.

Current infomation is gathered at the RPI Forum: http://www.raspberrypi.org/phpBB3/viewforum.php?f=87

Meego MER & XBMC
The MeeGo MER project provides a Linux-based, Open Source software platform for the next generation of computing devices. The MeeGo MER software platform is designed to give developers the broadest range of device segments to target for their applications, including netbooks, handheld computing and communications devices, in-vehicle infotainment devices, smart TVs, tablets and more – all using a uniform set of APIs based on Qt. XBMC is an award-winning free and open source (GPL) software media player and entertainment hub for digital media. Meego TV 1.2 uses XBMC as a reference GUI (that is, a starting point for creating a custom GUI).

ANDROID TRANSPORTER
The Android Transporter allows you to share display content wirelessly with remote screens in real time. Please be aware that the Transporter is still a technology study and it is missing the maturity of a full-featured product. However, we think that the Android Transporter is already exciting enough to let you play around with it. We believe that with the recently released Miracast standard you will get a very similar technology in upcoming Android devices, and we are considering making the Transporter compliant with the Miracast specs.

QUICK START GUIDE Let’s start with the Asus Nexus 7. By installing the Android Transporter firmware on your Asus Nexus 7 all data on the device will be removed including the contents of the /sdcard directory! So maybe you want to backup some data before you begin. To start, enable USB debugging on your Nexus 7 by switching on this option under Settings -> Developer options. Next, unlock the bootloader of your Nexus 7 device. This will void your device warranty and it will also do a factory reset! Install the adb and fastboot utilities. On Microsoft Windows you will also need Google’s USB drivers. Just search the Internet for instructions how to install this tools. Unlocking the bootloader is done by getting the device into the bootloader using the adb reboot bootloader command. Now unlock it with the fastboot oem unlock command. Download the Android Transporter firmware for the Asus Nexus 7 and unpack it. Reboot your Nexus 7 device into the bootloader using adb reboot bootloader. In the Android-Transporter directory you will find the flash script, which is called flash-all.sh. Be aware that the fastboot utility has to be available in the PATH environment for the flash script. Execute the flash script. Your Asus Nexus 7 is now ready. To switch back to the original Nexus 7 firmware image you should first download it fromGoogle’s factory images site. Then you can flash the original firmware image using the same instructions that you used to flash the Android Transporter firmware image.

Let’s move on to the Raspberry Pi. Download the Android Transporter firmware for the Raspberry Pi and unpack it. Insert an SD card into your card reader and flash the firmware image using the dd utility: sudo dd bs=1M if=esrlabs-rpi-android-transporter-2012-10-02.img of=/dev/sdX. Substitute /dev/sdX with the real SD card device name. For more information on flashing the Raspberry Pi see the Embedded Linux Wiki page for the Raspberry Pi. The Raspberry Pi is now also ready.

Next, you have to set up the networking between the two devices. You can either connect both devices to your home router or you can make use of the Raspberry Pi Wi-Fi hotspot. Both scenarios require the Raspberry Pi to be plugged into your home router. The Wi-Fi hotspot works with USB Wi-Fi adapters that are supported by the Realtek rtl8192cu Linux driver. We tested the Wi-Fi hotspot with the Netgear N150 Microadapter and with the Asus N13 Wi-Fi Stick. It works well with both Wi-Fi sticks except that we occasionally had some power consumption issues with the Asus device. If you want to make use of the Wi-Fi hotspot plug in the stick before the Raspberry Pi starts up. The network name of the Wi-Fi hotspot is RaspberryPiAP and the default password is E.S.R.Labs. The Wi-Fi hotspot may have the advantage that the Android Transporter has its own dedicated network to minimize the latency jitter during screen mirroring. If you connect both devices to your home router please make sure that the Wi-Fi transmitting power of your router is set to high. Otherwise you may experience high packet loss, which is bad for the Android Transporter.

When you now connect your Nexus 7 to the Wi-Fi network and start the Android Transporter you should see the Raspberry Pi in the list of available media hubs. The Raspberry Pi has announced itself as media sink via service discovery. Just tap on the Raspberry Pi item to start the screen mirroring. If you want to stop the screen mirroring just pull down the notification bar and click the Android Transporter “Switch off” item.

By default the Android Transporter will make use of the H.264 over RTP over UDP streaming protocols according to RFC3984. If you are in a building with a lot of Wi-Fi networks, it may be possible that the Android Transporter does not work really well because of high packet loss. If that is the case you should switch to the H.264 over RTP over TCP streaming protocols according to RFC3984 and RFC4571. You can do this in the preferences of the Android Transporter app. The latency will typically be around 20-30ms higher when using the reliable TCP transport protocol.

Enjoy the Android Transporter tech demo.

The Android Transporter is a custom ROM and not an app since we had to make adjustemts to various parts of the Android platform to make it happen.
