General info about the ACKspace Raspberry Pi board

For quick starters, Power is provided via the µ-USB or via GPIO pins. There is (standard) no USB slave software available when you plug in the device to your host (for stupido's this means,you won't see the device)

Note

There is a Raspberry Pi in the space for you to experiment with. If your RasPi project makes it to raspberrypi.org, hackaday.com or the like, I (Xopr) will give you that RasPi. For convenience, bring your own >=2GB SD card.

RPi XBMC

If you want to use XBMC on your RPi, you can use either of the following images.
RaspBMC (still in beta, use the release found on the frontpage!)
OpenELEC (remember that you have to setup a complete build environment for this one)
OpenELEC-07062012.tar.bz2 Download a complete working OpenELEC image for the RPi. Later here will be described how to install this image onto a SD card.

Must have RPi XBMC

Get more free cpu usage time (using OpenELEC)

1. Make sure you have the RPi running
2. Login to the RPi via SSH
3. Type the following command

 nano /storage/.xbmc/userdata/advancedsettings.xml

1. Paste the following text into the editor

 <advancedsettings>
   <gui>
     <algorithmdirtyregions>3</algorithmdirtyregions>
     <nofliptimeout>0</nofliptimeout>
   </gui>
 </advancedsettings>

1. Save the file and reboot the RPi

Overclock the RPi (using OpenELEC)

1. Create a file named config.txt and save this file onto the SYSTEM partition on the SD-Card
2. type the following text into this file

 arm_freq=850

1. Reboot the RPi
2. Login to SSH on the RPi
3. Type the following command

 cat /proc/cpuinfo

1. The output will look like this:

 Processor		: ARMv6-compatible processor rev 7 (v6l)
 BogoMIPS		: 847.05
 Features		: swp half thumb fastmult vfp edsp java tls 
 CPU implementer	: 0x41
 CPU architecture	: 7
 CPU variant		: 0x0
 CPU part		: 0xb76
 CPU revision		: 7
 
 Hardware		: BCM2708
 Revision		: 0002
 Serial			: 000000000a5256dc

1. Look at the line BogoMIPS. This line will read something around the 850 and is a representation of the RPi MHz
