Diese Webseite erfasst alle Informationen über den extrem kostengünstigen (ca. 15 GBP bzw. 25 USD) Linuxcomputer der Raspberry Pi Foundation, dessen Ziel es ist, Kindern beim Erlernen der Programmierung von Computern eine Hilfe zu sein.

Die Raspberry Pi Foundation ist eine in England registrierte wohltätige Organisation (Registrierungsnummer 1129409) deren Vorhaben es ist, das Studium der Computerwissenschaften und ähnlicher Themen, insbesondere auf Schulniveau, zu fördern, und dafür zu sorgen, dass das Erlernen des Umgangs mit Computern wieder Spaß macht. Wir gehen davon aus, dass dieser Computer sowohl in Industrie- als auch in Entwicklungsländern viele andere Anwendungen findet.

Bitte beachten Sie, dass das Raspberry Pi noch nicht erhältlich ist – Diese Seite ist ein sich in Arbeit befindliches Gemeinschaftswerk, in Vorbereitung auf die Veröffentlichung

Es wird in zwei Konfigurationen verfügbar sein: Modell A und Modell B. Für ein voll funktionsfähiges Modell A wird ein Preis von 25 US-$ erwartet, für Modell B ca. 35 US-$.

Components
(PCB IDs are those of the Model B Alpha board)

Based on a new Broadcom media processor (Raspberry Pi are currently redacting the chip model number in comments on their forum).


 * SoC: Broadcom BCMxxxx media procesor system-on-chip featuring:
 * CPU core: ARM1176JZF-S ARM11 core clocked at 700MHz; ARM VFP.
 * GPU core: an unnamed Broadcom proprietary GPU providing Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode. There are 24 GFLOPS of general purpose compute and a bunch of texture filtering and DMA infrastructure.  Eben worked on the architecture team for this and the Raspberry Pi team are looking at how they can make some of the proprietary features available to application programmers
 * DSP core: There is a DSP, but there isn't currently a public API (Liz thinks the BC team are keen to make one available at some point)
 * RAM: 128MiB (Model A) or 256MiB (Model B) of SDRAM. The RAM is physically stacked on top of the Broadcom media processor (package-on-package technology)
 * Either 1x USB 2.0 (Model A) or LAN9512 (Data Brief | Data Sheet) providing 10/100Mb Ethernet and 2x USB 2.0 (J10: Model B)
 * 1.27mm header providing ~16 GPIOs at 3v3, I2C and SPI interfaces
 * 1.27mm header providing MIPI CSI-2 & DSI interfaces
 * J1: DC Jack (6-20v input provisionally)
 * HDMI connector providing HDMI 1.3a out
 * SD/MMC/SDIO memory card slot
 * J5: JTAG (ARM11)
 * J6: Audio connector: 3.5mm stereo jack
 * J7: Composite Video connector: RCA


 * Board size: Credit-card or smaller.
 * Weight: <40g?
 * Currently 6 layer PCB; target: 4 layer

Handbuch
Eine Dokumentation wird bei der Veröffentlichung des Gerätes erhältlich sein. (momentanes Ziel ~November 2011)

Schematic / Layout

 * PCB mask
 * Prototype1 board

Clocking

 * Provisional main CPU clock speed is 700MHz
 * No data currently released on the GPU or other component clock speeds

Power management

 * Target power consumption is <1W

DLP Pico projector
The boards have both Composite and HDMI outputs so should interface with a range of DLP Pico projectors on the market.

Interfacing to Raw LCD Panels
No data currently available.

If the touchscreen interface talks via USB, they choose Linux as an OS, and there's Linux support for the touchscreen, the answer would be "yes".

General Purpose Input/Output (GPIO), I2C, SPI
There are approximately 16 spare GPIOs, which are brought out to 1.27mm pin-strip. Voltage levels are 3v3. The connector choice is deliberately annoying to connect to directly; there is no over-voltage protection on the board so the intention is that people interested in serious interfacing will use an external board with buffers, level conversion and analog I/O rather than soldering directly onto the main board.

We also bring 2x I2C (3v3) and an SPI (3v3) interface out to the same connector.

MIPI CSI-2 & DSI
We also bring out MIPI CSI-2 & DSI interfaces to a 1.27 mm pinstrip.

=BootRom=

The boards do not include NAND or NOR storage - everything is on the SD card, which has a FAT32 partition with GPU firmware and a kernel image, and an EXT2 partition with the rootfs.

We're not currently using a bootloader - we actually boot via the GPU, which contains a proprietary RISC core (wacky architecture ;). The GPU mounts the SD card, loads GPU firmware and brings up display/video/3d, loads a kernel image, resets the SD card host and starts the ARM.

You could replace the kernel image with a bootloader image, and that would work fine.

=Code=

Code and binaries for Raspberry Pi will be available at various places from launch.

Source
=Compiler=

The Broadcom processor on Raspberry Pi contains an ARM v6 general purpose processor and a GPU of currently unknown origin. No data is currently available on other cores (if any) available in the BCMxxxx.

ARM
There is broad compiler support including gcc - please see ARM Compilers

GPU
The GPU provides APIs for Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode.

The GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure - the Raspberry Pi team are looking at how they can make this available to application programmers.

DSP
There is a DSP, but there isn't currently a public API (Liz thinks the BC team are keen to make one available at some point).

=Development environments=

Instead of just using compiler + editor, you can use complete image create "development tool chains" which integrate compiler, build system, packaging tools etc. in one tool chain.

Ubuntu
Ubuntu is currently listed as the default distribution on the Raspberry Pi website.

Eben says (regarding default distribution): "Either Ubuntu or Fedora; the main point in Fedora’s favour is their ongoing support for ARMv6 architectures."

Meego & XBMC
The MeeGo project provides a Linux-based, open source software platform for the next generation of computing devices. The MeeGo 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).

RISC OS
RISC OS is a fast and lightweight computer operating system designed in Cambridge, England by Acorn. First released in 1987, its origins can be traced back to the original team that developed the ARM microprocessor. RISC OS includes BBC BASIC which was primarily conceived to teach programming skills as part of the BBC computer literacy project.

GeeXboX ARM
GeeXboX is a free and Open Source Media-Center purposed Linux distribution for embedded devices and desktop computers. GeeXboX is not an application, it’s a full-featured OS, that one can boot as a LiveCD, from a USB key, an SD/MMC card or install on its regular HDD. The GeeXboX distribution is lightweight and designed for one single goal: embed all major multimedia applications as to turn your computer into an HTPC.

Scratchbox
Scratchbox is a cross-compilation toolkit designed to make embedded Linux application development easier. It also provides a full set of tools to integrate and cross-compile an entire Linux distribution. To find out what it can do, take a look at some of the documentation.

Flash
From Eben: "We'll have to take a look. We support hardware-accelerated OpenVG, and have had Flash Lite running incredibly fast. Personally, I'd like to get the official hardware-accelerated Flash 10 going on there, running against OpenGL ES 2.0, but that's something to think about after the launch."
