1 Introduction
- The NanoPi2 is a high performance ARM Board developed by FriendlyARM for Hobbysts, Makers and Hackers for IOT projects. It features Samsung’s Cortex-A9 Quad Core S5P4418@1.4GHz SoC and 1G 32bit DDR3 RAM. It has built-in WiFi and Bluetooth which supports 802.11 b/g/n and Bluetooth 4.0. It boots Android and Debian from a TF card. It integrates an HDMI and LCD interface. Its adoption of the Raspberry Pi’s GPIO pin header makes it compatible with both Raspberry Pi’s external GPIO modules and Arduino’s shield boards. Its PCB dimension is 75 x 40 mm.

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 编译Linux kernel
5.5.1 编译内核
- 下载内核源代码
git clone https://github.com/friendlyarm/linux-3.4.y.git cd linux-3.4.y git checkout s5p4418-nanopi2
NanoPi2内核所属的分支是s5p4418-nanopi2，在开始编译前先切换分支。
- 编译Android内核
make nanopi2_android_defconfig touch .scmversion make CROSS_COMPILE=arm-eabi- uImage
- 编译Debian内核
make nanopi2_linux_defconfig touch .scmversion make CROSS_COMPILE=arm-eabi- uImage
编译成功结束后，新生成的内核烧写文件为 arch/arm/boot/uImage 。
5.5.2 编译内核模块
Android包含内核模块，位于system分区的 /lib/modules/ 下，如果您有新的内核模块或者内核配置有变化，则需要重新编译。
首先编译内核源代码中的模块：
cd linux-3.4.y make CROSS_COMPILE=arm-eabi- modules
另外有2个内核模块的源代码位于Android源代码中，可使用以下命令来编译：
cd /opt/FriendlyARM/s5p4418/android ./vendor/friendly-arm/build/common/build-modules.sh
其中 “/opt/FriendlyARM/s5p4418/android” 是指Android源代码的TOP目录，使用参数“-h”可查看帮助。
编译成功结束后，会显示生成的内核模块。
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。
