  • Default userName: pi
    Default password: raspberry

  • Current procedure Sept 2024:
      Per raspberryPi.com/software
    • "Download and install raspberry Pi Imager to a computer with an SD card reader.
      Put the SD card you'll use with your Raspberry Pi into the reader and run Raspberry Pi Imager.
        To install Imager, open terminal:
        $ sudo apt install rpi-imager
      • The procedure:
        Open Linux Mint menu (lower left corner of screen),
        type imager in search bar,
        "Imager" with rpi logo should be listed. Click to open it.
        Raspberry Pi Imager v1.7.2 (or your version) will open.
      • Left button asks to "Choose OS"
        I selected the 32-bit version (another time did the 64-bit version...). This rPi-01 is a Pi-1 B+ and is only 32-bit
      • Right button asks to "Choose Storage"
        Plug SD card of your choice into USB port with reader.
        "Generic mass storage xxGB" option or something similar will come up. Select it.
      • Now a Write button comes up on the screen. Click it.
        Answer yes to prompt warning all existing data will be overwritten.
      • Write and verification process will take several minutes.

      • Confirm/verify:
        Insert SD card into rPi and boot up, then open terminal:
          $ cat /etc/os-release

        will print out current version of your OS.

      -------------------------------------------

    • There were other procedures/methods described on the raspberryPi.com page,
      for manually downloading and installing "from source",
      but the Imager works easily and so far without issue.

    -----------------------------------------------------------------


    Old procedure using NOOBS:

  • Startup/setup procedure for model B+:
    (This assumes there's no software loaded on the SD card...)
    • Sparkfun has a good setup/startup tutorial:
      (link to:) SparkFun
    • It gives instructions for setting up the SD card, formatting it and installing NOOBS. NOOBS is like an intermediary installer program. It contains a selection menu where you can pick whatever ops sys software you want to use.
      Since my Rpi came up with NOOBS installed, I'm proceeding with installation.
        • OTOH, here's how I did it when my SD card got corrupted and I had to create a new one:
      • Download NOOBS zip file to your PC
      • Extract all files into default directory offered.
      • Copy all the extracted files into your formatted SD card (my 16GB card came pre-formatted)
        Do NOT include the root directory (the "default offered/created" when you extracted)
        Files on my NOOBS v.2.4.3 were 3 directories: defaults, os, & overlays, plus 17 files of various kinds

    • Insert formatted and loaded SD card into rPi.
    • Plug HDMI cable from rPi to monitor
    • Connect keyboard & mouse to USB ports
      • However I'm using a Logitech wireless keyboard/mouse, so I just plug in the dongle to the rPi.
    • plug in wifi dongle.
    • Connect power to rPi from USB source to micro-USB on rPi
    • Red power LED should come on. If mpu is booting, green "activity" LED will come on.
      (when you power down, green LED will go out when it's done/down)
    • First time through, it booted up and came to a dialog box titled "NOOBS v1.3.8 - Built: Jun 20 2014".
      • A bunch of operating systems were available, with Raspbian recommended. I clicked on install, a warning came up, saying it would overwrite anything on the SD card. Selected Raspbian and installation appears to have worked (took several minutes).
      • After lots of scrolling text, a dialog box came up.
        • Per SparkFun, default user is: pi, and default password is: raspberry. Did not change them.
        • Selected boot to desktop GUI, and set Pacific timezone, then rebooted.
    • Raspbian came up.
    • Get most current version:
      • Open LXT and execute:
        • sudo apt-get update
        • sudo apt-get upgrade
        • It takes several minutes to finish
        • The update/upgrade is recommended whenever (before) you do any major installations.
          It happened once that (I think during the upgrade,) I got a bunch of errors suggesting it could not connect to the archive website. I restarted the browser and all worked when repeated.

    • Connect to wifi:
      • You must either:
        have a rPi board with built-in wifi, or
        have a wifi dongle installed.
      • Click network icon in lower left task bar
        click wifi network desired
        enter "pre-shared key"

    ---------------------------------------------

  • Problems:
    • Yellow lightning bolt in top left of screen:
      This means you are not supplying enough power to the rPi.

    • Ran around in circles trying to get my keyboard to map correctly. Dumb gotcha: needed to select "US" instead of "UK" in config.
    • If you need to go back and re-config for any reason, open LX terminal, and type: sudo raspi-config
  • ...
