Raspberry-pi : my notes

Raspberry-pi is a general purpose computer, that comes in the size of a credit card. The type B has 512 MB of memory and it comes with a ARM processor. It also has general purpose I/O (GPIO) which enables you to drive external I/O interfaces by means of programming. This getting started notes are for my own reference. 

  • Download the OS image for Raspberry-pi from [1]
  • Copy the OS image to the SD card using dd command 
For that get the SD card drive name using 'df -h' command. Un-mount the drive and use dd to copy the image.
dd bs=4M if=2012-08-08-wheezy-armel.img of=/dev/mmcblk0
  • plug in the SD card to the RP device and boot it up.
  • To install java to wheezy:debian distribution use this version [2]
boot up the device, and assign a hard IP address,

  • ipconfig eth0
after that you can ssh, from you PC to you Ras-Pi.

  1. Now you can buy Raspberry Pi, Beagle Bone and pcDuino in Sri Lanka through LankaTronics. All these boards are ARM based and supports popular Linux distros and Android.

    If you take the pcDuino, it has a 1GHz processor, 1GB RAM, HDMI port, Ethernet port and 2-USB ports. Very powerful board to work with.

    Aptinex (the mother company of LankaTronics) is the authorised agent of Sri Lanka for Arduino, pcDuino, Digilent and Digi.

    I hope this will help someone who is looking to buy these in Sri Lanka after reading this interesting article of Pradeep.
