Android Linux Kernel compilation

Platform:

wind7_64 + ubuntu12_04_64 + VMware

Here take Android5.0 as an example:

Android5.0 can be downloaded here:
115 Network Tray Gift Pack code: 5LBD7CRTK1WZ
Http://115.com/lb/5lbd7crtk1wz

Linux_source_goldfish can be downloaded here:
115 Network Tray Gift Pack code: 5lbd76rru5or
Http://115.com/lb/5lbd76rru5or

Need to use OPENJDK7

apt-get install openjdk-7-jdkapt-get install openjdk-7-jre

Once the compilation is complete, set the tool chain path, which is convenient for compiling the kernel:

Export path= $PATH:/root/work/android/android-5.0/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/ Bin

Compile kernel:

After downloading the kernel, unzip

[Email protected]:~/work/android/android5/goldfish# git branch-a  master  remotes/origin/head-origin/ Master  remotes/origin/android-3.10  remotes/origin/android-3.4  remotes/origin/ android-goldfish-2.6.  in  remotes/origin/android-goldfish-3.10  remotes/origin/android-goldfish-3.4  remotes/origin/linux-goldfish-3.0-wip  remotes/origin/master

Since the kernel used by the Android5.0 simulator is 3.4 (you can start an emulator with the emulator's own kernel and then look at the kernel version cat/proc/version), we also use 3.4:

[Email protected]:~/work/android/android5/goldfish# git checkout remotes/origin/android-goldfish-3.4 -B linux-3.4

Then modify the Makefile

ARCH        = armcross_compile    ? = arm-eabi-

Configuring the Kernel

[Email protected]:~/work/android/android5/goldfish# make Goldfish_armv7_defconfig

Note: This default kernel does not configure the module load function, need to execute make menuconfig setting, otherwise cannot compile and load kernel module

Compiling the kernel

Make Zimage-j2

Start the emulator with our compiled kernel:

[Email protected]:~/work/android/android5/android-5.0# Emulator64-arm-kernel. /goldfish/arch/arm/boot/zimage
