Tutorial Build Kernel Android

Tested on Galaxy Gio..

Tools that you need to build the kernel :

Quote:git
ARM Compiler Toolchain
Kernel Source Code

How to get kernel source code :

1. Download at support files below
2. Download from github
#. At your android, Open terminal and type:

Quote:git clone https://github.com/iksteen/android_kerne..._galaxygio

#. Now we need to make a repo, type:

Quote:mkdir ~/bin
PATH=~/bin:$PATH
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
mkdir WORKING_DIRECTORY
cd WORKING_DIRECTORY
repo init -u https://android.googlesource.com/platform/manifest -b gingerbread

#. Give your name and email address, choose the color
#. Next, type:

Quote:repo sync -j32

and wait until it`s done to sync.

Make sure you already have all application that need before do the next steps.


Build custom kernel for samsung galaxy gio

1. still in terminal, type:

Quote:mkdir android
mkdir sources
mkdir .Galaxy_Gio_Sources

2. Hold ctrl+H on your home.
3. Move your kernel source code to folder that you created and name it .Galaxy_Gio_Sources
4. Copy paste ARM toolchain to source code folder
5. go to source code folder and open makefile
6. in makefile, find this:

Quote:#ARCH?= $(SUBARCH)
CROSS_COMPILE=

change to

Quote:#ARCH?= arm
CROSS_COMPILE= ./arm-2009q3/bin/arm-none-linux-gnueabi-

7. Back to terminal and type :

Quote:cd android
cd sources

8. next, type:

Quote:ln -s /home/*name of your desktop/.Galaxy_Gio_Sources/android_kernel_samsung_galaxygio

9. Additional note:
You can find config.gz file in your handphone with root explorer. it`s locate in proc/*config.gz. Copy those file to SDcard.
Move to /android/sources/android_kernel_samsung_galaxygio/kernel/

10. Type this command before compile

Quote:export CCOMPILER=~/arm-2009q3/bin/arm-none-linux-gnueabi-

or

Quote:export CCOMPILER=/home/*name of your desktop/arm-2009q3/bin/arm-none-linux-gnueabi-

11. next

Quote:make ARCH=arm CROSS_COMPILE=$CCOMPILER gio_rev03_defconfig

12. next

Quote:make ARCH=arm CROSS_COMPILE=$CCOMPILER

or directly w/o use export commands. Like these :

Quote:cd android
cd sources
cd android_kernel_samsung_galaxygio
chmod ugo+rwx bin

13. then

Quote:make menuconfig
make ARCH=arm CROSS_COMPILE=/home/delano/android/sources/android_kernel_samsung_galaxygio/arm-2009q3/bin/arm-none-linux-gnueabi- [Example}

or

Quote:make menuconfig
make ARCH=arm CROSS_COMPILE=/home/delano/android/sources/android_kernel_samsung_galaxygio/arm-2009q3/bin/arm-none-linux-gnueabi- -8[Example}
