Running Linux on a Raspberry Pi

Raspberry Pi is a modern single board computer which can run Linux on it. No need to explain the advantages of Linux comparing to any other operating system that can run on low resourced embedded platforms. Unlike other embedded platforms where Contiki or TinyOS can run, this new platform Raspberry Pi with Linux provides almost all the capability we can have on a standard computer.

Recently we received a Raspberry Pi to our lab for a project work and I received the opportunity to work with it. It is a product of Raspberry Pi Foundation in UK. There are different customised distributions of Linux available for Raspberry Pi device. We boot this device from a live SD card. It has ports to connect different peripherals like audio and video devices, keyboard and mouse. However most prominent way to use this device is to connect it to a LAN via the Ethernet port and then log in to the device remotely from a SSH terminal.
 In addition to the standard ports available in the board, Raspberry Pi contains some more GPIO pins which can be used to connect different other external devices to the Raspberry Pi. By searching on the Internet I found various interesting applications and projects  done by using Raspberry Pi devices. Therefore it seems like Raspberry Pi is going to dominate the embedded systems world.
