RPi Easy SD Card Setup

=SD Card setup= To boot the Raspberry Pi, you need an SD card installed with a bootloader and a suitable Operating System. Some Raspberry Pi kits will come with a ready-to-go card, but if you didn't receive one you will need to prepare your own:

Official images are available from http://www.raspberrypi.org/downloads and there is an overview of available distributions here.

Warning! When you write the Raspberry Pi image to your SD card you will lose all data that was on the card.

=Safest/Laziest way= Buy a preloaded card from RS Components or element14.

=Easiest way=


 * Use an installer program. The Fedora ARM Installer will download and install Raspberry Pi Fedora Remix images, but it will also install other images if they are already downloaded and in uncompressed or .gz format.


 * (Mac) The RasPiWrite utility is a python script which will walk you through the process of installing to SD card, it works with any Raspberry Pi compatible disk image, and can download one of the currently available distros if you don't have one.

=Easy way=

To write your SD card you start by downloading the SD image (the data you will write to the card). The best way to do this is using BitTorrent. This generally results in a faster download as it is a highly distributed system (you will be downloading the data from users who have previously downloaded it).

This guide assumes you have downloaded the Debian "squeeze" image, with name debian6-13-04-2012. Obviously, if you are downloading a different or newer version, use the name of the version you have downloaded.

Copying the image to an SD Card on Windows
''In Windows the SD card will appear only to have a fairly small size - about 75 Mbytes. This is because most of the card has a partition that is formatted for the Linux operating system that the RPi uses and is not visible in Windows. ''
 * 1) Download the  image from a mirror or torrent
 * 2) * http://www.raspberrypi.org/downloads
 * 3) Extract the image file debian6-19-04-2012.img from the debian6-19-04-2012directory in the debian6-19-04-2012.zip
 * 4) Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer.
 * 5) Download the Win32DiskImager utility.  The download links are on the right hand side of the page, you want the binary zip.
 * 6) Extract the zip file and run the Win32DiskImager utility. You may need to run the utility as Administrator.
 * 7) Select the debian6-19-04-2012.img image file you extracted earlier
 * 8) 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 computer's hard disk!
 * 9) Click Write and wait for the write to complete.
 * 10) Exit the imager and eject the SD card.
 * 11) Insert the card in the Raspberry Pi, power it on, and it should boot up.  Have fun!

Copying the image to an SD Card on Windows if first option isn't successful
I wasn't able to choose device in Win32DiskImager on my notebook so I found a different way to achieve the same thing on windows machine..

C:/flashnul/flashnul.exe -p
 * 1) Download the image from a mirror or torrent
 * 2) * http://www.raspberrypi.org/downloads
 * 3) Extract the image file debian6-19-04-2012.img from the debian6-19-04-2012 directory in the debian6-19-04-2012.zip
 * 4) Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example H:) by looking in the left column of Windows Explorer.
 * 5) Download flashnul software from http://shounen.ru/soft/flashnul/ here is Translated version
 * 6) * Download the latest version at the time of writing it was flashnul-1rc1.
 * 7) * Download and Extract the application from archive.
 * 8) * Click Start button > All Programs > Accessories > Command Prompt, right click on it and Run as Administrator.
 * 9) * Run the flashnul with argument:
 * 1) * Flashnul will tell you something like:

Avaible physical drives: 0      size = 250059350016 (232 Gb) 1      size = 1990197248 (1898 Mb) Avaible logical disks: C:\ D:\ F:\ G:\ H:\ Press ENTER to exit. '''SDCARD number is on left! In my case it is number 1''' C:/flashnul/flashnul.exe 1 -L C:/debian6/debian6-19-04-2012.img where flashnul.exe   -L   C:/flashnul/flashnul.exe H: -L C:/debian6/debian6-19-04-2012.img
 * 1) * Now we will use Load argument:
 * 1) * Flashnul will give you a device summary and proceed caution, have a quick scan through the information to make sure you have selected the correct device, then type yes and press enter.
 * 2) * If you get a access denied error, try re-plugging the SD card. Also make sure to close all explorer windows or folders open for the device.
 * 3) * If you still get a access denied error, try substitute the device number with the drive letter followed by a colon. Eg:
 * If the device summary does not match Your card (the size is smaller, e.g. 75MB), but you are sure, that the letter is correct - please continue and then try again with the device number.

Copying an image to the SD Card in Mac OS X
Note: Some users have reported issues with using OSX to create SD Cards.


 * 1) Download the  image from a mirror or torrent
 * 2) * http://www.raspberrypi.org/downloads
 * 3) Verify if the the hash key is the same (optional), in the terminal run:
 * 4) * shasum ~/Downloads/debian6-19-04-2012.zip
 * 5) Extract the image:
 * 6) * unzip ~/Downloads/debian6-19-04-2012.zip
 * 7) * (or: just double click the zip, it will extract automatically)
 * 8) From the terminal run df -h
 * 9) Connect the sdcard reader with the sdcard inside
 * 10) Run df -h again and look for the new device that wasn't listed last time.  Record the device name of the filesystem's partition, e.g. /dev/disk3s1
 * 11) Unmount the partition so that you will be allowed to overwrite the disk:
 * 12) * diskutil unmount /dev/disk3s1
 * 13) * (or: open Disk Utility and unmount the partition of the sdcard (do not eject it, or you have to reconnect it))
 * 14) Using the device name of the partition work out the raw device name for the entire disk, by omitting the final "s1" and replacing "disk" with "rdisk":
 * 15) * e.g. /dev/disk3s1 => /dev/rdisk3
 * 16) In the terminal write the image to the card with this command, using the raw disk device name from above:
 * 17) * sudo dd bs=1m if=~/Downloads/debian6-19-04-2012/debian6-19-04-2012.img of=/dev/rdisk3
 * 18) * (note that dd will not feedback any information until it is finished, information will show and disk will re-mount when complete)
 * 19) After the dd command finishes, eject the card:
 * 20) * diskutil eject /dev/rdisk3
 * 21) * (or: open Disk Utility and eject the sdcard)
 * 22) Insert it in the raspberry pi, and have fun

Copying an image to the SD Card in Linux (command line)
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.


 * 1) Download the zip file containing the image from a mirror or torrent
 * 2) * http://www.raspberrypi.org/downloads
 * 3) Verify if the the hash key of the zip file is the same as shown on the downloads page (optional). Assuming that you put the zip file in your home directory (~/), in the terminal run:
 * 4) * sha1sum ~/debian6-19-04-2012.zip
 * 5) * This will print out a long hex number which should match the "SHA-1" line for the SD image you have downloaded
 * 6) Extract the image, with
 * 7) * unzip ~/debian6-19-04-2012.zip
 * 8) Run df -h to see what devices are currently mounted
 * 9) 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.
 * 10) Run df -h again. The device that wasn't there last time 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, so 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: in fact it will if you have previously written a Raspberry Pi image to this SD card, because the RPi SD images have more than one partition.
 * 11) 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. So run the command below, replacing "/dev/sdd1" with whatever your SD card's device name is (including the partition number)
 * 12) * umount /dev/sdd1
 * 13) * 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.
 * 14) In the terminal write the image to the card with this command, making sure you replace the input file if= argument with the path to your .img file, and the "/dev/sdd" in the output file of= argument with the right device name (this is very important: you will loose all data on the hard drive on your computer if you get 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)
 * 15) * dd bs=1M if=~/debian6-19-04-2012/debian6-19-04-2012.img of=/dev/sdd
 * 16) * Note that if you are not logged in as root you will need to prefix this with sudo 
 * 17) * 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, or you can run pkill -USR1 -n -x dd in another terminal (prefixed with sudo if you are not logged in as root).
 * 18) As root run the command sync or if a normal user run sudo sync (this will ensure the write cache is flushed and that it is safe to unmount your SD card)
 * 19) Remove SD card from card reader, insert it in the Raspberry Pi, and have fun

Copying an image to the SD Card in Linux (graphical interface)
If you are using Ubuntu and hesitate to use the terminal, you can use the ImageWriter tool (nice graphical user interface) to write the .img file to the SD card.


 * 1) Download the zip file containing the image from a mirror or torrent
 * 2) * http://www.raspberrypi.org/downloads
 * 3) Right click the zip file and select "Extract here"
 * 4) * ATTENTION: As of this writing (15 June 2012), there is a bug in the ImageWriter program that causes it to fail if the filename of the image file or its path (i.e. all the names of any parent folders that you extract the image file into) contain any space characters. Before going any further, ensure that neither the file name of the image you're using or the path contain any spaces (or other odd characters, for that matter). A bug has been opened for this issue: https://bugs.launchpad.net/usb-imagewriter/+bug/1013834 Once the issue is fixed, edit this page to advise people to use an updated/patched version of ImageWriter.
 * 5) Insert the SD card into your computer or connect the SD card reader with the SD card inside
 * 6) Install the ImageWriter tool from the Ubuntu Software Center
 * 7) Launch the ImageWriter tool (it needs your administrative password)
 * 8) Select the image file (example debian6-19-04-2012.img) to be written to the SD card (note: because you started ImageWriter as administrator the starting point when selecting the image file is the administrator's home folder so you need to change to your own home folder to select the image file)
 * 9) Select the target device to write the image to (your device will be something like "/dev/mmcblk0" or "/dev/sdc")
 * 10) Click the "Write to device" button
 * 11) Wait for the process to finish and then insert the SD card in the Raspberry Pi

=Manually resizing the SD card partitions (Optional)= The SD card image is sized for a 2GB card. The Fedora Remix will automatically resize the partitions on the card during the first boot. The Debian version won't, so you'll have to do it manually. It's much easier if you do this on another machine, as the SD card can't be mounted when you do this.

Look here for instructions.

=Adding a data partition (Optional)= If you would rather not resize the partition on another machine as described above, either because you do not have another working Linux machine or you wish to keep your data on another partition to your operating system, you can instead create a new data partition and have that mount automatically at boot.

 * First you need to become root and install parted (I did all of this from the boot command prompt, although if you feel safer in a GUI, you can do all of this in a terminal window):
 * Then you need to run parted on your SD card, mine is /dev/mmcblk0, ymmv:
 * Once running, set the display units to something usable and then print your partition table
 * You should see something like this:
 * Now you need to create your data partition - you need to choose one more than the end of partition 3 with ,0,0 as your start and use the number from the line that starts with Disk as your end:
 * That should show your new partition:
 * Now quit and format the partition (again, ymmv with the specific device name, try ls /dev for some clues), and then label it:
 * Now we need to make sure that the partition is mounted automatically when the system boots (maybe don't use vi if you never have before, try nano):
 * Enter a line exactly like this at the end of the file and save and quit your text editor:
 * Create the mount point:
 * Now mount the partition:
