Raspberry Pi

 
 
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It's capable of doing everything you'd expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

Operating system used
OpenElec

Software prerequisites
none


Procedure
  1. Check your current Raspberry Pi 1 model B hardware info:

    Goto Kodi home screen
    Select menu: System | System Info
    Select: Hardware
    You should see:
    CPU: ARMv6-compatible processor rev 7 (v6)
    CPU temperature: 40oC
    CPU speed: 700MHZ


  2. Make sure SSH is enabled.

    Goto Kodi home screen
    Select menu: System | OpenELEC
    Select: Services
    Select: Enable SSH

  3. Install Putty on your computer.
    We will remotely access the Raspberry Pi with the computer using the Putty program.

  4. Start Putty and enter the following information:
    Host Name (or IP address): 192.168.1.69

    Press the Open button.

    Enter the Raspberry Pi IP address

  5. A terminal window opens. Enter the following login information:
    login as: root
    password: openelec

    Enter the Raspberry Pi login information

  6. To overclock the Raspberry Pi we need to modify the /flash/config.txt file.
    The /flash partition is read-only. We need to remount /flash with the read-write permission.

    Type: mount -o remount,rw /flash

  7. Edit the /flash/config.txt file.
    Type: nano /flash/config.txt

    Mount config.txt file

  8. The config.txt opens.
    The default clock settings for the Raspberry Pi 1 model B (no overclocking):
    ARM (arm_freq): 700 MHZ
    Core (core_freq): 250 MHZ
    SDRAM (sdram_freq): 400 MHZ
    Overvolt: 0

    No overclock settings in the Raspberry Pi

  9. We will set our Raspberry Pi to a High mode overclock settings.

    YOU USE THIS SETTING AT YOUR OWN RISK. MOBILEFISH.COM WILL NOT BE LIABLE FOR ANY DATA LOSS, DAMAGES, LOSS OF PROFITS OR ANY OTHER KIND OF LOSS WHILE USING OR MISUSING THIS SETTING.

    Change the following lines:

    # arm_freq=700
    # core_freq=250
    # sdram_freq=400
    # over_voltage=0

    to

    arm_freq=950
    core_freq=450
    sdram_freq=450
    over_voltage=6


    High mode overclock settings in the Raspberry Pi

    After you made your changes, save your file:
    Type: CTRL+X
    Type: Y
    Press Enter button

  10. The /flash partition should be set back to read-only. We need to remount /flash with the read only permission.

    Type: mount -o remount,ro /flash

  11. Reboot the Raspberry Pi, type in the terminal window: reboot

  12. Again check your Raspberry Pi 1 model B hardware info:

    Goto Kodi home screen
    Select menu: System | System Info
    Select: Hardware
    You should see:
    CPU speed: 950MHZ
