The Raspberry Pi Foundation just released the brand, spankin’ new version two. It’s packed with a BCM2836 Quadcore 900MHz ARMv7 processor, 1GB of RAM, 4 usb ports, an ethernet port, and loads over 15 seconds faster than it’s already-out-of-date sibling, the Model B+.

And guess what? 

The Raspberry Pi 2 won’t boot from older disk images. 

So, save yourself an enormous amount of hassle and run this to update your image:


sudo apt-get update
sudo apt-get upgrade
sudo rpi-update


You’ll be glad you did, I promise.

    That third command came out with: “Command Not Found”. I think you meant: “sudo rpi-update”

    My PI_2 not boot from the SD card of my PI_B +, Update, Upgrade, RPI Update.
    (SD card Sandisk Ultra 64 Go )
    No boot!

    PI_2 Boot and works well just with ISO NOOBS V 1.4.0

    What I forget

      Sorry to be disruptive French.
      but of my findings I take this experience:

      If I choose the NOOBS English language and French desk, all is well.
      If I choose NOOBS in the French language and French desk all goes wrong.
      Same problem led on two no boot.

      Just like when I want transferrer my programe of the SD card from my B + PI to PI 2

      On my SD card the vertion is in French and keybord FR.
      I can understand now why your upgrade works for you and not for me.
      Which confirms the rule or French are always hecklers. 🙂

      You can look at this and see the problem?
      I would feel less alone.

      Thank you for your help.
      best regards.
      The, French.

        Just one precision at the boot the session bloc on this point :

        26.781603 Unable to handle kernel NULL pointer dereference at virtual address 00000048

        26.79768 pgg = b84c0000

        and no suite. … ???

    I thought I had two bad Pi2’s because they wouldn’t boot… but two in a row !?? I downloaded the latest NOOBS from, still no joy. Perhaps PS too low – checked OK.

    Found a NOOBS 1.4.0 disk in the Raspberry Pi Geek magazine. Loaded its iso onto the micro SD. inserted the SD into Pi2 and Happy, Happy, Happy.

    After several attempts with different Google suggestions I found the final trick, “unplug the HDMI” cable and pluggit in, and then the Pi booted nicely.
