Raspberry Pi: getting started (Part II)

Hello again in this Tutorial we will have look to get started with Raspberry Pi (installation and more)

Which Raspberry Pi should you buy  :

Get any of the model of raspberry Pi that you thing will be suiting for you .But if need our advice then read below.

The Raspberry Pi lineup is now headlined by the Pi 2, but the B+ is sticking around and the A+ is also still available as an entry-level model. So which should you buy?

If you’ve got existing project running on the B+, you might be wary of making the leap due to compatibility issue, or have heard that some performance tests indicate the Pi 2’s battery life may be a concern for mobile projects. But you’re probably more excited by all the extra power you’d get to play with, so if you’re buying a new board, it’d be foolhardy to pay the same price for an inferior setup.

Our advice is to keep old applications running on the B+, but start tinkering with the Pi 2 going forward. More operating systems will enter the picture soon, plus you’ll get Windows 10 (for free!) in the near future. (Note that initial demand outstripped supply for the Pi 2, so keep an eye on the element 14 community for the latest availability).

I CONSIDER THAT NOW YOU HAVE A PI MODEL WITH YOU SO LET’S GET STARTED FROM INSTALLING THE RASPBIAN / NOOBS OS

OS choice :

In Raspberry pi we got two options when it is concert regarding the Os (operating System)

1. Raspian  Os: Raspbian is the Foundation’s official supported Operating System.

Install-Raspbian-Raspberry-Pi

2. Noobs Os: NOOBS is designed to make it easy to select and install operating systems for the Raspberry Pi without having to worry about manually imaging your SD card.

Third Party Os choice :

You also got some third party os to get install they seems to be like :

  • Windows 10 IOTcore
  • Openelec
  • Ubuntu Mate
  • PINET os
  • RiSC os
  • OSMC os

DOWNLOAD :

Download Raspbian  :

Download Raspbian os here

Download NOOBS :

In Noobs we gotta two options Noobs and Noobs Lite (Recommended Noobs  )

NOOBS is an easy operating system installer which contains Raspbian. It also provides a selection of alternative operating systems which are then downloaded from the internet and installed.

NOOBS Lite contains the same operating system installer without Raspbian pre-loaded. It provides the same operating system selection menu allowing Raspbian and other images to be downloaded and installed.

For Noobs Os you visit here

If its possible get a pre-installed OS  SD card.

INSTALLATION:

IN order to install Operating System Images  we  require a Raspberry Pi Operating System image on an SD card. You will need another computer with an SD card reader to install the image.

We recommend most users download NOOBS which is designed to be very easy to use. However more advanced users looking to install a particular image should use this guide.

WRITING AN IMAGE TO THE SD CARD :

With the image file of the distribution of your choice, you need to use an image writing tool to install it on your SD card.

See  guide for your system:

  • Linux
  • Mac OS
  • Windows

INSTALLING OPERATING SYSTEM IMAGES ON LINUX

Please note that the use of the dd tool can overwrite any partition of your machine. If you specify the wrong device in the instructions below you could delete your primary Linux partition. Please be careful.

  • Run df -h to see what devices are currently mounted.
  • If your computer has a slot for SD cards, insert the card. If not, insert the card into an SD card reader, then connect the reader to your computer.
  • Run df -h again. The new device that has appeared is your SD card. The left column gives the device name of your SD card; it will be listed as something like /dev/mmcblk0p1 or /dev/sdd1. The last part (p1 or 1 respectively) is the partition number but you want to write to the whole SD card, not just one partition. Therefore you need to remove that part from the name (getting, for example, /dev/mmcblk0 or /dev/sdd) as the device for the whole SD card. Note that the SD card can show up more than once in the output of df; it will do this if you have previously written a Raspberry Pi image to this SD card, because the Raspberry Pi SD images have more than one partition.
  • Now that you’ve noted what the device name is, you need to unmount it so that files can’t be read or written to the SD card while you are copying over the SD image.
  • Run umount /dev/sdd1, replacing sdd1 with whatever your SD card’s device name is (including the partition number).
  • If your SD card shows up more than once in the output of df due to having multiple partitions on the SD card, you should unmount all of these partitions.
  • In the terminal, write the image to the card with the command below, making sure you replace the input file if= argument with the path to your .imgfile, and the /dev/sdd in the output file of= argument with the right device name. This is very important, as you will lose all data on the hard drive if you provide the wrong device name. Make sure the device name is the name of the whole SD card as described above, not just a partition of it; for example sdd, not sdds1 or sddp1; or mmcblk0, not mmcblk0p1.dd bs=4M if=2015-11-21-raspbian-jessie.img of=/dev/sdd
  • Please note that block size set to 4M will work most of the time; if not, please try 1M, although this will take considerably longer.
  • Also note that if you are not logged in as root you will need to prefix this with sudo.
  • The dd command does not give any information of its progress and so may appear to have frozen; it could take more than five minutes to finish writing to the card. If your card reader has an LED it may blink during the write process. To see the progress of the copy operation you can run pkill -USR1 -n -x dd in another terminal, prefixed with sudo if you are not logged in as root. The progress will be displayed in the original window and not the window with the pkill command; it may not display immediately, due to buffering.
  • Instead of dd you can use dcfldd; it will give a progress report about how much has been written.
  • You can check what’s written to the SD card by dd-ing from the card back to another image on your hard disk, truncating the new image to the same size as the original, and then running diff (or md5sum) on those two images.
  • The SD card might be bigger than the original image, and dd will make a copy of the whole card. We must therefore truncate the new image to the size of the original image. Make sure you replace the input file if= argument with the right device name. diff should report that the files are identical.
  • Run sync; this will ensure the write cache is flushed and that it is safe to unmount your SD card.
  • Remove the SD card from the card reader.

INSTALLING OPERATING SYSTEM IMAGES USING WINDOWS:

  • Insert the SD card into your SD card reader and check which drive letter was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer. You can use the SD Card slot (if you have one) or a cheap SD adaptor in a USB port.
  • Download the Win32DiskImager utility from the Sourceforge Project page (it is also a zip file); you can run this from a USB drive.
  • Extract the executable from the zip file and run the Win32DiskImagerutility; you may need to run the utility as administrator. Right-click on the file, and select Run as administrator.
  • Select the image file you extracted above.
  • Select the drive letter of the SD card in the device box. Be careful to select the correct drive; if you get the wrong one you can destroy your data on the computer’s hard disk! If you are using an SD card slot in your computer and can’t see the drive in the Win32DiskImager window, try using a cheap SD adaptor in a USB port.
  • Click Write and wait for the write to complete.
  • Exit the imager and eject the SD card.
