Raspberry Pi SD image - RISC OS (operating system)

Informatie (ENG)

RISC OS is not a flavour of Linux. It’s not a type of Unix. It’s certainly got nothing to do with Windows! RISC OS is its own thing – a very specialised ARM-based operating system. So if you’ve not used it before, you will find it doesn’t behave quite the same way as anything else. We think it’s better!

Note: RC14 supports all Raspberry Pi models A, A+, B, B+ and Model 2 B. With the latest firmware, it also supports the Compute Module/IO Board.

It contains all the elements required to run RISC OS, including the firmware to initialise the Raspberry Pi as well as the HardDisc4 boot files, in an SD card image which can be written to a blank SD card using a tool such as Win32DiskImager.

Once written to the SD card all you have to do is turn on the Raspberry Pi and it will start up in RISC OS with a lot of preloaded software. The ROM image is RISC OS 5.21 (17-Feb-2015) and is held inside $.!Boot.Loader where you will see the other firmware files as well:

The RISC OS ROM image will be written to each time you shut down (by the SDCMOS module, this makes sure any ‘CMOS’ settings are kept up to date) hence updating the datestamp of the ‘RISCOS/IMG’ file.

These files appear to the Raspberry Pi as the only files in the FAT partition on the SD card as it starts up.

Within RISC OS you will see a complete hard disc of files which means that you can start right away:

When it first starts up you will be shown the Welcome Guide which explains things such as how to download more RISC OS software using either the !Store or the !PackMan utility. Each of these shows you a list of RISC OS software, with a detailed explanation of what each bit of software does and lets you choose which items to download.

Changes in the disc image since RC12
====================================
New items
---------
The !Internet resource now includes the 'MD5' utility for crosschecking file checksums.

A new diversion, !Hopper is included which is a RISC OS version of the popular frogger game.

Improvements to existing items
------------------------------
ChangeFSI can now reliably open an even wider range of obscure bitmap formats, including improvements to handling of Sun raster files, Targa, OS/2 BMP files, icons and cursor definition from Windows 3 (.ICO and .CUR).

The card game !Patience uses solid dragging of cards during game play and offers configurable game variations amongst numerous other enhancements.

Font conversion utility !T1ToFont no longer crashes during the font conversion process.

The screen mode setup plugin for !Configure no longer presents a jumbled menu of resolutions when clicked.

Booting up with a disc locked against changes with FSLock will honour the existing Choices directory rather than auto creating a blank one and losing all the settings for that session.

The MimeMap file includes a wider range of commonly encountered internet Mime types than previously.

Printing fonts via the bitmap printer drivers should be more reliable in certain edge cases, such as applications using memory in high addresses.

Changes in the operating system ROM since RC12
==============================================
New items
---------
This ROM now includes support for the Mark 2 Model B Raspberry Pi hardware, using the newer BCM2836 system on chip and a total of 1GB of RAM. The Model A, A+, B, and B+ are still supported.

A driver for DS1307 (and similar) real time clock chips is includes. As the Pi doesn't include RTC hardware, this add on needs to be purchased seperately.

The new BlendTable module helps with transparency display of Sprites.

Improvements to existing items
------------------------------
The kernel now understands and can render sprites with alpha levels of transparency, rather than its previous binary level, with the help of changes made to the SpriteExtend and ColourTrans support modules. The Window Manager similarly can make use of alpha transparency, including automatically searching for them when the *IconSprites command is used.

!Paint will open the new format sprites, as well as giving much more detailed information about them in the detailed view. !Paint no longer crashes when dragging the sliders in the CMYK colour selection dialogue.

The kernel now supports a much wider array of pixel buffer formats for the screen, in addition to the traditional 'BGR' format. The extra support allow for 4k and 64k colours where hardware permits, as well as variants on the 32bpp modes previously available. Developers should consult the updated GraphicsV documentation on the ROOL website for details.

Expression evaluation in obey files using OS_GSTrans is now more reliable when the expression uses an angle bracket < >.

DragASprite, responsible for rendering file drags in the Filer, now uses the alpha transparency facilities to draw desktop drags rather than using a cross hatch pattern.

The USB driver, DWCDriver, now uses fast interrupts to handle some of the load from the USB peripheral. Previously normal interrupts might miss some key up or mouse click events when the system was busy.

The Filer can now sort directories numerically as well as alphabetically, and will typically open directory viewers quicker thanks to an improved redraw algorithm.

DOSFS will now create short versions of filenames that match the recommendations set out by Microsoft meaning that, for example, copying or renaming the Pi's BOOTCODE.BIN will be successful where the Pi firmware doesn't look for the mixed case (long) version of the filename.

SDFS in conjunction with FileCore is more accurate at tracking discs ejected from card sockets that don't have a card detect pin.

The sound system and built in voices now adjust their data rate to match changes in the sampling rate, so the pitch and tempo is correct when the sampling rate is changed.

Wide text files shown in !Edit used to be incorrectly rendered when the screen was wider than 256 characters, this limit has been increased considerably.

Ethernet uploads via the EtherUSB driver are now considerably quicker than in earlier release candidates, typically factors of 10x to 20x depending on the protocol being used.

A number of ROM modules which previously included hardwired English text have now been internationalised, so non English speakers can replace the text with translations using a !Territory application.

The tokenisation of BASIC line numbers in some situations has been fixed.

The Debugger can now dump VFP exception registers with the *ShowVFPRegs, and the VFPSupport module handles extra accuracy of VFP instructions not natively supported by the Pi's processor.
