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 如何编译系统

5.1 抢建开发环境

5.2 安装交叉编译器

编译U-Boot和Linux可以直接使用Android源代码中的提供的交叉编译器，假设您的Android源代码已下载好，可以通过设置环境PATH来使用它： 

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

其中“/opt/FriendlyARM/s5p4418/android”是Android源代码目录。
使用Android中的交叉编译器时，编译U-Boot和Linux应指定 CROSS_COMPILE=arm-eabi- 。

5.3 编译U-Boot

下载U-Boot源代码并编译，注意分支是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-

编译成功结束后您将获得u-boot.bin，您可以通过fastboot来更新正在运行的NanoPi2板上SD的U-Boot。
注意：您不能直接使用dd来更新SD卡，否则有可能会导致无法正常启动。

5.4 准备mkimage

编译内核需要用到U-Boot中的工具mkimage，因此，在编译内核uImage前，您需要保证您的主机环境可以成功运行它。
你可以直接使用命令 sudo apt-get install u-boot-tools 来安装，也可以自己编译并安装： 

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。
