3. Compilation Method.

3.1. bootloader compile

Proceed to compile after you unzip in as follows.

$ tar xvjf android.tar.bz2

Configure the directory as follows..

WORK\android\kernel

\bootable\bl2

\bootloader

Enter the Bootloader folder.

You can check the Toolchain used to compile the Bootloader in Makefile.

$ vi Makefile

CROSS_COMPILE := $(shell pwd)/../../prebuilts/gcc/linux-x86/aarch64/aarch64-linux-

android-4.9/bin/aarch64-linux-android-

$ ./build.sh avl8895

You can check the image in the “output” folder.

Enter the folder /bootable/bl2 to continue compiling. In this folder, an image related to “bl2”

is created.

You can check the Toolchain used to compile the Bootloader in “build.sh”

$vi build.sh

$./build.sh smdk8895_aarch64

You can check the image in the “output” folder.

$cd output

SMDK8895_bl2.bin : DRAM setup and uboot load.

u-boot.bin : Used on an exynos8895 AVL board.

The image below is required by default for Booting.

bl1 : bl1 (Samsung released)

bl2 : SMDK8895_bl2.bin (compile to generate)

uboot : u-boot.bin (compile to generate)

el3 : el3 (Samsung released)

3.2. Kernel compile

Enter the Kernel folder.

$ cd kernel/

You can check the Toolchain used to compile the Kernel in “build.sh”

$ vi build.sh

The Toolchain of the above path is included in the Android.

KERNEL_CROSS_COMPILE_PATH="../prebuilts/gcc/linux-x86/aarch64/aarch64-linux-

android-4.9/bin/aarch64-linux-android-"

Run the command below to continue the compilation.

$ cp mv8895_new2p8_defconfig .config

$./build.sh

Once the compilation in complete, you can check the image generated from the path below.

PATH : arch/arm64/boot

3.3. Android compile

OpenJDK-8 must be installed instead of OpenJDK-7 to continue compiling.

3.3.1. OpenJDK-8 settings.

Install OpenJDK-8 by running the following command:

$ sudo update-alternatives --config java

Select the java to be used by number. “0” was selected to use OpenJDK-8.

In the same way as above, make the following changes:

$ sudo update-alternatives --config javac

Java version check.

$ java -version

3.3.2. Nougat compile.

Enter the Android folder.

(You must compile the kernel before proceeding with the Android compiles.)

$ ./build.sh avl8895

Once the compilation in complete, you can check the image generated from the path below.

PATH : /out/target/product/avl8895
