Raspbian Wheezy

Wheezy armel image
Features include:
  • minimal Raspbian Wheezy installation (similar to a netinstall)
  • Hard Float binaries: floating point operations are done in hardware instead of software emulation, that means higher performances
  • Disabled incremental updates, means apt-get update is much faster
  • Workaround for a kernel bug which hangs the Raspberry Pi under heavy network/disk loads
  • 3.6.11+ hardfp kernel with latest raspberry pi patches
  • Latest version of the firmwares
  • Fits 1GB SD cards
  • A very tiny 118MB image: even with a 2GB SD there is a lot of free space
  • ssh starts by default
  • The clock is automatically updated using ntp
  • IPv6 support
  • Just 14MB of ram usage after the boot
Here is the link to download my custom image:
Checksum MD5: e5b0d40f47a1fc2e4c2b80c99af538be

dd bs=1M if=raspbian_wheezy_20130923.img of=/dev/sdX
Finally, if you have an sd larger than 1GB, grow the partition with gparted (first move the swap partition at the end).
The root password is raspberry.

You will have to reconfigure your timezone after the first boot:
dpkg-reconfigure tzdata
The keyboard layout:
dpkg-reconfigure console-data
And the localization:
dpkg-reconfigure locales

Recover Raspberry Pi Image

Back Up/Restore Raspberry Pi Image 

Once you have spend some time installing and customizing your image and your happy that everything works as you want it to , it's time to create a back up of your image before you start messing about with the Pi.

Step1 

- To create the back up run the Discks utility on Ubuntu laptop
- Select the first partition on the SD card and create an image of the boot partition
- Next do the same for the root partition and keep them in the same back up folder as the original image



Step 2


Now if you happen to break your image simply insert the SD card back in your laptop
and execute the following command in your terminal
- # sudo dd bs=1M if=raspbian.img of=/dev/mmcblk0
- This will create brand new image on you SD card

Step 3
- Open the Discs utility on your Ubuntu laptop and select the SD card
- Repeat the steps above but instead of selecting Create image select your root partition and run Restore Image

You are ready to go again!!
