本目录为凌云实验室针对IGKBoard开发板移植的Yocto Hardknott (Yocto 3.3) 项目源码，关于Yocto系统的详细使用，大家可以参考NXP官方的用户手册文档，[点此链接下载](https://www.nxp.com/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf) 。







如果想源码编译Yocto系统的话，则系统需要满足：



* 推荐使用 Ubuntu 20.04 系统；

* 推荐使用 4核以上CPU；

* 硬盘空间至少要求 200GB+；







### 1. 下载Yocto源码







如果没有 ***git*** 命令，则首先安装 **git** 命令并配置 **git** 的账号信息:



```

guowenxue@ubuntu20:~$ sudo apt install git

guowenxue@ubuntu20:~$ git config --global user.name guowenxue

guowenxue@ubuntu20:~$ git config --global user.email "guowenxue@gmail.com"

```







首先下载并安装 google 的 ***repo*** 命令:



```

guowenxue@ubuntu20:~$ curl https://storage.googleapis.com/git-repo-downloads/repo -o repo

guowenxue@ubuntu20:~$ chmod a+x repo

guowenxue@ubuntu20:~$ sudo mv repo /usr/bin/ 
```







使用 **git** 命令克隆下载该项目源码：



```

guowenxue@ubuntu20:~$ mkdir -p ~/workspace

guowenxue@ubuntu20:~$ cd ~/workspace

guowenxue@ubuntu20:~/workspace$ git clone git://weike-iot.com/imx6ull.git

Cloning into 'imx6ull'...

remote: Counting objects: 330, done

remote: Finding sources: 100% (330/330)

remote: Getting sizes: 100% (179/179)

remote: Total 330 (delta 98), reused 330 (delta 98)

Receiving objects: 100% (330/330), 110.55 KiB | 884.00 KiB/s, done.

Resolving deltas: 100% (98/98), done.

```







使用 ***repo*** 命令下载 **Yocto Hardknott** 源码：



```

guowenxue@ubuntu20:~$ mkdir -p ~/workspace/imx-yocto-bsp/

guowenxue@ubuntu20:~$ cd ~/workspace/imx-yocto-bsp/

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-hardknott -m imx-5.10.52-2.1.0.xml

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp$ repo sync

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp$ ls

imx-setup-release.sh  README  README-IMXBSP  setup-environment  sources

```







### 2. 编译Yocto系统







首先将该本文件夹Yocto针对IGKBoard的移植源码拷贝到 Yocto 系统中。



```

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp$ cp -rf ~/workspace/imx6ull/yocto/meta-igkboard/ sources/

```







接下来执行下面命令，初始化 IGKBoard 开发板的 Yocto 编译环境：



```

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp$ MACHINE=igkboard source sources/meta-igkboard/tools/igkboard-setup.sh -b igkboard



 Build directory is  igkboard

/home/guowenxue/workspace/imx-yocto-bsp

    Welcome LingYun IoT Gateway Kit Board Yocto BSP



    The Yocto Project has extensive documentation about OE including a

    reference manual which can be found at:

        http://yoctoproject.org/documentation



    You can now run 'bitbake <target>'



    Common targets are:

        linuxsys-image

        core-image-minimal

        imx-image-full

```







接下来使用下面命令，开始Yocto系统的源码编译，这个系统编译时间较长，如果编译的过程中出现错误，再重新开始编译即可。也可以使用 ***-k*** 选项先跳过编译出错的软件包。



```

guowenxue@ubuntu20:/workspace/imx-yocto-bsp/igkboard$ bitbake linuxsys-image

```







### 3. Yocto编译输出







编译过程中下载的软件包存放在 ***~/workspace/hardknott_packets/*** 路径下:



```

guowenxue@ubuntu20:/workspace/imx-yocto-bsp/igkboard$ ls ~/workspace/hardknott_packets/

```







编译完成输出的系统镜像及文件系统存放在下面路径下：



```

guowenxue@ubuntu20:~/workspace/imx-yocto-bsp/igkboard$ ls ls tmp/deploy/images/igkboard/

linuxsys-image-igkboard-*.rootfs.tar.bz2   --Yocto根文件系统压缩包

linuxsys-image-igkboard-*.rootfs.wic.bz2   --Yocto烧录系统镜像文件

```
