Back to the introduction<\/a><\/p>\n

Today I have finally received the raspberry pi and its components by mail and I am preparing for the first step: creating an image of the wheezy raspbian distribution to copy on the memory card.<\/p>\n

This is the download site<\/a>, and these are the instructions to follow<\/a> to prepare the card in a Linux environment.<\/p>\n

    \n
  1. \n
      \n
    1. Download the wheezy package from the download site<\/li>\n
    2. Compare the SHA-1 checksum<\/strong> from the download site with your downloaded file by executing this from command line, after entering the directory containing your downloaded file:n\n
      sha1sum file.zip<\/pre>\n
      n where file.zip<\/em> is the name of your downloaded file. If the checksums are different you need to start from the beginning.<\/li>\n
    3. Unzip the downloaded file by performingn\n
      unzip file.zip<\/pre>\n
      n the result is a file with name file.img<\/em><\/li>\n
    4. Insert the SD memory card purchased in an available slot of yourn PC \/ laptop (laptop in my case)<\/li>\n
    5. Check the file systems mounted by performing: df -h<\/li>\n
    6. Figure out which mount point corresponds to your card, let\u2019s say \/dev\/sdb1, <\/em>and unmount it by\n
      umount \/dev\/sdb1<\/li>\n
    7. Now you need to copy the image file to your card, using the linux dd<\/strong> command. In my case this is performed by<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n
        \n
      1. <\/li>\n<\/ol>\n
          \n
        1. <\/li>\n<\/ol>\n
            \n
          1. <\/li>\n<\/ol>\n
              \n
            1. <\/li>\n<\/ol>\n
                \n
              1. <\/li>\n<\/ol>\n
                        dd bs=4M if=2012-12-16-wheezy-raspbian.img of=\/dev\/sdb<\/pre>\n
                Be careful of what you type above, and be sure of the output file system (\/dev\/sdb<\/em>), since this operation is destructive of whatever found on that output file system path. This process might required to be run as super user (sudo<\/strong>) and does not give any diagnostic. Also remove the partition number at the end of the output device (\/dev\/sdb and not \/dev\/sdb1), so that the image affects the entire SD card and not only one partition of it. Be prepared to wait for a few minutes.<\/p>\n
                Before removing the card, from the command line, run sync<\/strong>, to make sure that everything in the write cash is dumped onto the card.<\/p>\n
                You can now remove the card. It is ready to be inserted in your Raspberry Pi<\/strong><\/p>\n
