Note
  1. VDD_SYS_3.3V: 3.3V power output
  2. VDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB’s the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.6V

4 Get Started

4.1 Essentials You Need

要开启你的NanoPi新玩具,请先准备好以下硬件

  • NanoPi 2
  • microSD Card/TFCard: Class 10 or Above, minimum 8GB SDHC
  • microUSB cable
  • A Host running Ubuntu 14.04 64 bit system

4.2 Make an Installation MicroSD Card

  • 1) Insert your microSD card to your host running Ubuntu and check your SD card's device name
dmesg | tail

Search the messages output by "dmesg" for similar words like "sdc: sdc1 sdc2". If you can find them it means your SD card is recognized as "/dev/sdc". Or you can check that by commanding "cat /proc/partitions".

  • 2) Download Firmware Package
git clone https://github.com/friendlyarm/sd-fuse_nanopi2.git
cd sd-fuse_nanopi2
  • 3) Flash Android Firmware to MicroSD Card
su
./fusing.sh /dev/sdx

(Note: you need to replace "/dev/sdx" with the device name in your system) When you do “git clone” you have to hit “Y” within 10 seconds after it prompts you to download image files otherwise you will miss the download.

  • 4) Flash Debian Firmware to MicroSD Card
./fusing.sh /dev/sdx debian

4.3 Run Android

Insert a MicroSD card with Android image files to your NanoPi2, connect the NanoPi2 to an HDMI monitor and a 5V/2A power source the NanoPi2 will be automatically powered on. If you can see the blue LED flashing it means your board is working and you will see Android loading on the HDMI monitor. If at the same time you connect your NanoPi2 to a PC running Ubuntu and Minicom via a serial cable you will see system messages output to the PC’s minicom terminal.

5 Make Your Own OS Image

5.1 Setup Development Environment

5.2 Install Cross Compiler

FriendlyARM has an open source Android package which contains a working cross compiler. You can set it up in the "PATH" variable:

export PATH=/opt/FriendlyARM/s5p4418/android/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin:$PATH
arm-eabi-gcc -v

The “/opt/FriendlyARM/s5p4418/android” is where Android source code package is located.
When you use this compiler please specify the option "CROSS_COMPILE=arm-eabi-".

5.3 Compile U-Boot

Download the U-Boot source code and compile it. Please note the github's branch is s5p4418-nanopi2:

git clone https://github.com/friendlyarm/uboot_nanopi2.git
cd uboot_nanopi2
git checkout s5p4418-nanopi2
make s5p4418_nanopi2_config
make CROSS_COMPILE=arm-eabi-

After your compilation succeeds a u-boot.bin will be generated. If you want to test it please flash it to your installation MicroSD card via fastboot.
Warning: you cannot update this MicroSD card by commanding "dd". This command which will cause trouble when booting the NanoPi2.

5.4 Prepare mkimage

You need the mkimage utility to compile a U-Boot source code package. Please make sure this utility works well on your host before you start compiling a uImage.
You can install this utility by either commanding "sudo apt-get install u-boot-tools" or following the commands below:

cd uboot_nanopi2
make tools
mkdir -p /usr/local/sbin && cp -v tools/mkimage /usr/local/sbin

5.5 Compile Linux kernel

5.5.1 Compile Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux-3.4.y.git
cd linux-3.4.y
git checkout s5p4418-nanopi2

The NanoPi2's kernel source code lies in the "s5p4418-nanopi2" branch.

  • Compile Android Kernel
make nanopi2_android_defconfig
touch .scmversion
make CROSS_COMPILE=arm-eabi- uImage
  • Compile Debian Kernel
make nanopi2_linux_defconfig
touch .scmversion
make CROSS_COMPILE=arm-eabi- uImage

After your compilation succeeds a uImage will be generated in the "arch/arm/boot/" directory.

5.5.2 Compile Kernel Modules

Android contains kernel modules which are in the "/lib/modules" directory in the system section. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.
Compile Original Kernel Modules:

cd linux-3.4.y
make CROSS_COMPILE=arm-eabi- modules

Here we have two new modules and we can compile them by following the commands below:

cd /opt/FriendlyARM/s5p4418/android
./vendor/friendly-arm/build/common/build-modules.sh

The "/opt/FriendlyARM/s5p4418/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".
After your compilation succeeds new modules will be generated

5.6 编译Android

  • 搭建编译环境

搭建编译Android的环境建议使用64位的Ubuntu 14.04,安装需要的包即可。

sudo apt-get install zlib1g-dev:i386
sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex libncurses5-dev zlib1g-dev gawk minicom

更多说明可查看 https://source.android.com/source/initializing.html

  • 下载源代码

Android源代码的下载需要使用repo,其安装和使用请查看 https://source.android.com/source/downloading.html

mkdir android && cd android
repo init -u git@github.com:friendlyarm/android_manifest.git -b nanopi2-kitkat
repo sync

其中“android”是指工作目录,另外,初始化repo时也可以使用HTTPS clone URL。

  • 编译系统
source build/envsetup.sh
lunch aosp_nanopi2-userdebug
make -j8

编译成功完成后,目录 out/target/product/nanopi2/ 下包含可用于烧写的image文件。
