编译Ubuntu/Debian固件

你可以使用Fenix脚本来编译Ubuntu/Debian固件。

设置本地编辑环境

1
2
3
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install git make lsb-release qemu-user-static

下载Fenix脚本

下载Fenix脚本到本地路径,如:~/project/

1
2
3
$ mkdir ~/project/
$ cd ~/project/
$ git clone --depth 1 https://github.com/khadas/fenix

设置编译环境

你需要先设置Fenix编译环境,如:选择Khadas SBC型号、U-Boot版本、Linux版本、Linux发行版、安装方式等等。

1
2
$ cd ~/project/fenix
$ source env/setenv.sh

开始编译完整固件

在设置好环境执行make就会开始编译,编译过程会用到root权限,会提示你要输入密码才能继续编译。

1
$ make

提示:如果是你第一次编译,那么时间会比较久,因为脚本会检测你的电脑的编译环境,可能会安装编译需要的一些软件包,同时还会从Khadas Github下载一些仓库(如:U-Boot和Linux)。

你也可以选择单独编译U-Boot和内核。

编译U-Boot

1
$ make uboot

编译U-Boot debian包

1
$ make uboot-deb

编译内核

1
$ make kernel

编译内核debian包

1
$ make kernel-deb

编译GPU debian包

1
$ make gpu-deb

编译板级debian包

1
$ make board-deb

编译所有的debian包

1
$ make debs

编译uboot image

1
$ make uboot-image

清除linux源码树

1
$ make kernel-clean

打开linux配置菜单

1
$ make kernel-config

保存linux配置文件

1
$ make kernel-saveconfig

清除uboot源码树

1
$ make uboot-clean

编译选项

  • NO_CCACHE - ccache选项

    • 使能ccache(默认)
      • NO_CCACHE=no make
    • 禁止ccache
      • NO_CCACHE=yes make
  • COMPRESS_IMAGE - 压缩固件选项

    • 不压缩(默认)
      • COMPRESS_IMAGE=no make
    • 压缩固件
      • COMPRESS_IMAGE=yes make
  • BUILD_TYPE - 编译类型选项

    • Develop
      • BUILD_TYPE=develop make
    • Release
      • BUILD_TYPE=release make
  • DOWNLOAD_MIRROR - 源地址选项

    • 使用国内源
      • DOWNLOAD_MIRROR=china make

使用Docker编译

Fenix支持在Docker中编译,我们提供了一个Ubuntu 20.04的Docker环境,你可以在里面编译所有的固件。

安装Docker

请参考Docker官方安装文档

添加用户到Docker组

1
$ sudo usermod -aG docker $USER

注意:你需要注销或重启系统来使其生效。

检查Docker

1
$ docker run hello-world

如果你看到如下信息输出说明Docker安装成功:

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

在Docker中运行Fenix

获取Docker镜像:

1
2
$ cd ~/project/fenix
$ docker pull numbqq/fenix:latest

进入Docker环境:

$ docker run -it --name fenix -v $(pwd):/home/khadas/fenix \
-v /etc/localtime:/etc/localtime:ro \
-v /etc/timezone:/etc/timezone:ro \
-v $HOME/.ccache:/home/khadas/.ccache --privileged \
--device=/dev/loop-control:/dev/loop-control \
--device=/dev/loop0:/dev/loop0 --cap-add SYS_ADMIN \
numbqq/fenix

现在已经在Docker容器里面了,可以开始编译了:

1
2
khadas@919cab43f66d:~/fenix$ source env/setenv.sh
khadas@919cab43f66d:~/fenix$ make

下一次可以用如下命令启动Docker:

1
2
$ docker start fenix
$ docker exec -ti fenix bash
