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。

 PLEASE CHECK BOARD GPIO POWER DOMAIN CONFIGURATION !!!!!

 Check Node [pmu_io_domains] in the file: /home/forlinx/3568/OK3568-linux-source/kernel/arch/arm64/boot/dts/rockchip/OK3568-C-linux.dts 

 请再次确认板级的电源域配置！！！！！！
 <<< 特别是Wi-Fi，FLASH，以太网这几路IO电源的配置 >>> ！！！！！
 检查内核文件 /home/forlinx/3568/OK3568-linux-source/kernel/arch/arm64/boot/dts/rockchip/OK3568-C-linux.dts 的节点 [pmu_io_domains]

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";
};

保存，编译

成功

8. 烧录

烧录成功

9. XSHELL登录提示 received:3,expected:20

解决办法：

在/etc/ssh/sshd_config最后一行加入

KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1

问题解决

10. OK3568 UART8无法使用

打开UART8发送数据，卡死，查了以下，是由于与蓝牙复用问题，参考网上的方法：去除掉/etc/init.d/S97BT 脚本可执行权限。
执行命令chmod -x /etc/init.d/S97BT。
执行命令sync，同步操作。
执行命令reboot，重启开发板。

或修改

vi /etc/init.d/bluetooth-setting.sh 

注释掉下面那行
#!/bin/sh
#hciattach /dev/ttyS8 any -s 115200 115200 flow > /dev/null
 

解决!

11. 编译Ubuntu系统

依次执行./bulid.sh

ln -rsf ubuntu-20.04-release/parameter.txt rockdev/parameter.txt
ln -rsf ubuntu-20.04-release/ubuntu.img rockdev/rootfs.img
./build.sh updateimg
ls rockdev/update.img

cp -v rockdev/update.img /mnt/hgfs/forlinx/image/

使用烧录软件烧录，即可。注意：烧录前最好先删除FLASH
