* Raspbian Wheezy [#j8c51e4c]
>
Raspbian Wheezy is available at the official page of Raspberry Foundation.~
[[Raspbian Wheezy: 2015-05-05-raspbian-wheezy.img:https://www.raspberrypi.org/downloads/raspbian/]]~
The details of the image of Raspbian Wheezy are as following:~

**Size of Image [#h152722c]
>
The size of image is 3.1GB approximately.~

**debian version [#b1e5d816]
>
Raspbian Wheezy is compatible with debian wheezy (7.x). The debian version of Raspbian Wheezy is 7.8.

** kernel [#i1d63f54]
>
Initially, the version of kernel is 3.18.11.
<Code>
This kernel is built on x86 by using the cross toolchain gcc 4.8.3 of linaro.
<Code>

**gcc [#q162a0c7]
>
The version of gcc at the default setting is 4.6.3. This gcc is built for armv6 vfp handfloat.
<Code>

**Package [#gcbde55a]
>
Since a lot of packages are installed in Raspbian Wheezy, the installed microSD card can be used as it is inserted into the microSD card drive of Raspberry Pi. Including MetaPackages and libraries, totally 853 packages are included in Raspbian Wheezy. It contains the full packages for desktop managements such as printing functions, managing moving images, voice and sound. It includes the libraries for development and packages for programing languages. OpenCV and Wolfram-Engine are also included initially. The boot-up of OS is done by SysVinit.~

** Update [#zc2657f7]
>
As of October 2015, to apply apt-get update and apt-get upgrade, the packages are updated. Once the update of respberrypi-bootloader is done, the kernel is updated from 3.18.11 to 4.1.7 without making a backup copy of kernel.~
<Code>
To execute rpi-update, the kernel is updated to 4.1.10. Unlike the update of raspberrypi-bootloader, rpi-update saves the contents of the /boot/ partition into the /boot.bak/ of rootfs, and the original kernel modules are stored into /lib/modules/ and /lib/modules.bak/.
<Code>



As rpi-update is executed on 3.18.11 kernel, which is kept original setting as 2015-05-05-raspbian-wheezy is written into a microSD card, the directory under /lib/modules/ is changed as it is shown below.
<Code>
 In their name of directory, the “-v7” suffix indicates that its directory is for Raspberry Pi 2 (ARMv7 architecture).~
~
After the kernel is updated to 4.1.7 and rpi-update is executed, the directory under /lib/modules/ is changed as it is shown below.~
<Code>

If you need 3.x.x kernel or any other reason that you often bring back the original condition,
