1、下载镜像，百度网盘地址：下载链接：https://pan.baidu.com/s/1DclTp0drvzRI78qhl1aVDQ 提取码: 3tra
2、下载完成后打开\OK3568-C_Forlinx Desktop 20.04_用户资料-20220721\手册 下面的《OK3568-C_Forlinx Desktop 20.04_用户编译手册_V1.0 20220721.pdf》，并认真阅读。
3、按照提示安装好虚拟机。这里特别提醒一下，内存最好设置8G，要不编译时，内存不够就会往写到磁盘里，这样速度就会慢。
4、按照3.1.6安装基本库：
forlinx@ubuntu:~$ sudo apt-get update //更新下载源信息
forlinx@ubuntu:~$ sudo apt-get install build-essential //提供编译程序必须软件包的列表信息
forlinx@ubuntu:~$ sudo apt-get install libncurses* //用于生成基于文本的用户界面
forlinx@ubuntu:~$ sudo apt-get install lzop //基于 Lzo 库的压缩解压工具
forlinx@ubuntu:~$ sudo apt-get install net-tools //网络配置工具
forlinx@ubuntu:~$ sudo apt-get update //更新 apt-get 下
载源
forlinx@ubuntu:~$ sudo apt-get install openssh-server vim git fakeroot //必备工具包的
安装
forlinx@ubuntu:~$ sudo apt-get install repo git ssh make gcc libssl-dev liblz4-tool expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib unzip device-tree-compiler python-pip libncurses5-dev
程序源码：用户资料\Linux\源码\OK3568-linux-source.tar.bz2，有三个文件，需要一起拷过去：
创建工作目录：
lugl@lugl-virtual-machine:~$ sudo mkdir -p /forlinx/3568
利用ftp工具把文件拷到虚拟机
进入到目录3568：
/forlinx/3568$ cat OK3568-linux-source.tar.bz2.a* > OK3568-linux-source.tar.bz2
tar -xvf OK3568-linux-source.tar.bz2
解压出来后删除原来的压缩包，太占工空间了：
lugl@lugl-virtual-machine:~/forlinx/3568$ ls
OK3568-linux-source
进入解压出来的目录：
lugl@lugl-virtual-machine:~/forlinx/3568/OK3568-linux-source$ ls
app debian envsetup.sh Makefile rkbin u-boot
buildroot device external mkfirmware.sh rkflash.sh ubuntu-20.04-release
build.sh docs kernel prebuilts tools yocto
执行编译命./build.sh 对话框输入选择1：
lugl@lugl-virtual-machine:~/forlinx/3568/OK3568-linux-source$ ./build.sh
You're building on Linux

CPU、内存立马上来了，编译就是吃硬件资源呀，如果你想编译顺利，切记硬盘要留出100G以上的空间，内存留出8G左右的空间，要不会报莫名其妙的错误。
编译一段时间后会弹出下图界面，需要选择，提取图中信息，VCCIO4 和 VCCIO6 选择 1800000 其余的选择 3300000，使用上下方向按键选择选项，按回车确认选择即可。（不要选错，选错就会报错，停止）
编译完后会弹出如下：
接下来出现了报错：

然后再编译就是通不过了：

【是不是我用的是ubuntu22.04】环境不对。。。
没办法先去下载一下飞凌提供的环境：百度网盘 (baidu.com)提取码：c2hv
烧硬盘呀。。。
换了飞凌的虚拟机，继续编译：
昨晚太晚了，让主机在自己编译，早上起来报错如下：

搜了一下错误 ：
2022-11-27T14:50:45 ninja: build stopped: subcommand failed.
2022-11-27T14:50:46 Makefile.gn_run:398: recipe for target 'run_ninja' failed
查找了一下错误，说是由于服务器进程打开文件数受限制。
1.vim /etc/security/limits.conf 添加如下的行
2.保存后，再输入ulimit -n 10240回车即可生效。
3、提示 ulimit 命令 执行：
sudo sh -c "ulimit -n 65535 && exec su $LOGNAME"
还是继续报错：

后面发现内存不足引起的错误，后面加了内存到32G终于编译成功了：
然后把生成的update.img下载到开发板，编译的工作就基本结束了。
【总结】全源码编译，第一需要耐心，第二生产力的电脑要给力。3、需要看错误提示，主要是工具包有些没有安装。
