+本目录为凌云实验室针对IGKBoard开发板移植的Yocto Honister (Yocto 3.4) 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 Honister** 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-honister -m imx-5.15.5-1.0.0.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/honister/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, You can run 'bitbake <target>' now.
+
+ The targets should be:
+ 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/honister_packets/*** 路径下:
+
+```
+guowenxue@ubuntu20:/workspace/imx-yocto-bsp/igkboard$ ls ~/workspace/honister_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
+```
