OK3568 forlinx系统编译过程及问题汇总

1. 共享文件夹无法加载；通过网上把文件夹加载后，拷贝文件很慢，任务管理器查看发现硬盘读写速率很低。解决办法：重新安装vmware tools。

2. 拷贝Linux源码到虚拟机，解压。

3. 虚拟机基本库安装
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

以上顺利完成

4. 编译OK3568 Linux源码必要库安装

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

以上顺利完成

5. Qt Creator安装

不安装了，先试下

6. 编译

./build.sh

漫长的等待，不知道等了多少个小时，搞了大半天，卡在QT那里不动，于是回头重装QT。然后：

./build.sh cleanall

./build.sh

00:51分开始编译，看看要什么时候可以结束

14点多完成编译，共花了13个多小时，提示build.sh指令错误，所在行1077，打开文件，最后一行1066。

因为自己调整了build.sh设备树，为了确认是不是自己的问题，重新解压，重新编译。

编译成功

7. 修改设备树，禁用PCIE

&pcie30phy {
status = "disabled";
};

&pcie3x2 {
reset-gpios = <&gpio0 RK_PC6 GPIO_ACTIVE_HIGH>;
enable-gpios = <&gpio0 RK_PA5 GPIO_ACTIVE_HIGH>;
vpcie3v3-supply = <&vcc3v3_sys>;
status = "disabled";
};

&pcie2x1 {
reset-gpios = <&gpio0 RK_PB6 GPIO_ACTIVE_HIGH>;
vpcie3v3-supply = <&vcc3v3_sys>;
status = "disabled";
};
