2.4. Download Method.

2.4.1. SD booting Download Method.

Set the OM Switch to SD Booting Mode as show.

SD Booting Mode

Then insert the SD Booting Card into the board. Connect the battery to the board and press

the “PW ON” button.

Run the following command in uboot mode :

$ fastboot

Enter the download command after cmd run.




Write fwbl1 / bl2 / el3 / bootloader on the board.

$ fastboot flash fwbl1 bl1

$ fastboot flash bl2 SMDK8895_bl2.bin

$ fastboot flash el3_mon el3

$ fastboot flash bootloader u-boot.bin

Next, reboot the switch by changing it to the UFS Booting Mode.

UFS Booting Mode

Press the enter bar before the count reaches zero before the entry into boot mode.


$ fastboot





Partition Image

$ fastboot flash partition_table partition

$ fastboot flash ldfw ldfw

Kernel Image

$ fastboot flash dtb exynos8895-avl8895.dtb

$ fastboot flash kernel Image

Android Image

$ fastboot flash ramdisk ramdisk-uboot.img

$ fastboot flash –S 700M system system.img

If you have finished so far, the image download is complete. Please reboot and make sure

that Android boots correctly.

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

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

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 apt-get install openjdk-8-jdk




OpenJDK-8 cannot be verified as shown above.. Proceed with the installation by adding the

$sudo add-apt-repository ppa:openjdk-r/ppa

$sudo apt-get update

OpenJDK-8 can be viewed as shown below.




$sudo apt-get install openjdk-8-jdk

Select “Y”.




After installation, run the following command to select the version

$ 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
