二、编译全志A64的内核

1.查看帮助

$cd lichee  
$ ./build.sh -h
Top level build script for lichee

Examples:
1. Set the config option
    $ ./build.sh config
2. Build lichee using preset config value
    $ ./build.sh
3. Pack a linux, dragonboard image
    $ ./build.sh pack
4. Build lichee using command argument
    $ ./build.sh -p <platform>

flags:
  -p,--platform:  platform to build, e.g. sun9iw1p1 (default: '')
  -k,--kernel:  kernel to build, e.g. 3.3 (default: 'linux-3.4')
  -b,--board:  board to build, e.g. evb (default: '')
  -m,--module:  module to build, e.g. buildroot, kernel, uboot, clean (default: '')
  -h,--[no]help:  show this help (default: false)

2.利用build.sh配置内核，选择主板型号

litin@linuxService:~/Android/allwinner/cqa64_android_v5.1/lichee$ ./build.sh config

Welcome to mkscript setup progress

   1. t1_v1

三.编译安卓源码

1.选择产品型号

我的产品型号是 tulip_t1，则选择：7

litin@linuxService:~/Android/allwinner/cqa64_android_v5.1/android$ source build/envsetup.sh 
including device/softwinner/common/vendorsetup.sh
including device/softwinner/tulip-t1/vendorsetup.sh

including sdk/bash_completion/adb.bash

litin@linuxService:~/Android/allwinner/cqa64_android_v5.1/android$ lunch 

You're building on Linux

Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_arm64-eng
     3. aosp_mips-eng
     4. aosp_mips64-eng
     5. aosp_x86-eng
     6. aosp_x86_64-eng
     7. tulip_t1-eng
     8. tulip_t1-user
     9. tulip_t1_v1-eng
     10. tulip_t1_v1-user
     11. mini_emulator_arm64-userdebug
     12. mini_emulator_mips-userdebug
     13. mini_emulator_x86-userdebug
     14. m_e_arm-userdebug
     15. mini_emulator_x86_64-userdebug
     16. aosp_shamu-userdebug
     17. aosp_flo-userdebug
     18. aosp_manta-userdebug
     19. aosp_flounder-userdebug

Which would you like? [aosp_arm-eng] 7

sudo ./build.sh pack

百度一下，发现其他人也遇到这个问题，但原因不一：

（1）打包安卓系统遇到bootfex CreateFile failed 2和Dragon execute imagecfg Failed ! 错误

（2）求助！全志方案pack打包镜像出错，Dragon execute image.cfg Failed ! ArgCnt = 3, 400 [问题点数：20分，结帖人sgsxcwen]

3.pack打包的时候要求配置安卓镜像输出的路径“ERROR: please specify ANDROID_IMAGE_OUT env”

解决方法：在pack文件里面配置安卓的编译输出路径“ANDROID_IMAGE_OUT”即可

vi lichee/tools/pack/

添加下面路径即可

ANDROID_IMAGE_OUT=~/Android/allwinner/cqa64_android_v5.1/android/out/target/product/tulip-t1_v1/

4.全志内核的配置文件在哪？

第一次使用全志平台，在编译内核的时候由于找不到内核配置文件，会让人找不到方向，其实它就在linux内核源码里面
