基础信息

用户密码

系统使用root用户在tty终端自动登录,同时也支持root用户ssh远程登录。

用户:root
密码:root

网络设置

系统使用NetworkManager管理网络,默认为以太网配置了动态IP,可以使用nmcli命令来配置网络。

使用nmcli命令配置网络

设置静态IP示例

查看已创建的连接:

nmcli connection show
...
有线连接 1  36ff5fe1-088a-3562-a9f1-70e9552ce8b6  ethernet  eth0
...

若已存在关于网络接口eth0的连接,需先删除:

nmcli connection delete '有线连接 1'

添加名为my_static_eth0的静态IP连接:

nmcli connection add con-name my_static_eth0 ifname eth0 type ethernet ip4 10.168.1.157/24 gw4 10.168.1.1

设置DNS:

nmcli connection modify my_static_eth0 ipv4.dns "10.168.1.1 119.29.29.29"

设置动态IP示例

查看已创建的连接:

nmcli connection show
...
有线连接 1  36ff5fe1-088a-3562-a9f1-70e9552ce8b6  ethernet  eth0
...

若已存在关于网络接口eth0的连接,需先删除:

nmcli connection delete '有线连接 1'

添加名为my_dynamic_eth0的动态IP连接:

nmcli connection add con-name my_dynamic_eth0 ifname eth0 type ethernet

连接WIFI示例

查看WIFI网络列表:

nmcli device wifi list
...
IN-USE  SSID             MODE  CHAN  RATE        SIGNAL  BARS  SECURITY  
        OrayBox-3D28     红外  9     130 Mbit/s  65      ▂▄▆_  WPA2      
        NORCO-5G         红外  1     130 Mbit/s  59      ▂▄▆_  WPA2      
...

连接名为OrayBox-3D28密码为norco85258506的WIFI:

nmcli device wifi connect OrayBox-3D28 password norco85258506

命令用法举例

查看网络接口状态:

nmcli device status

查看网络接口网络信息:

nmcli device show eth0

使用连接:

nmcli connection up my_static_eth0

不使用连接:

nmcli connection down my_static_eth0

查看连接详细信息:

nmcli connection show my_static_eth0

关闭WIFI:

nmcli radio wifi off

打开WIFI:

nmcli radio wifi on

连接WIFI并设置静态IP:

nmcli con add con-name "my_wifi" type wifi ifname wlan0 ssid "OrayBox-3D28" -- wifi-sec.key-mgmt wpa-psk wifi-sec.psk "norco85258506" ipv4.method manual ipv4.address 10.168.1.158/24 ipv4.dns 119.29.29.29 ipv4.gateway 10.168.1.1

创建名为my_hotspot的WIFI热点:

nmcli dev wifi hotspot ifname wlan0 ssid "my_hotspot" password "88888888"

固件打包烧录

导出主板上的根文件系统分区镜像rootfs.img

1. 将U盘的第一个分区格式化成ext4格式

2. 在U盘的第一个分区根目录下创建export_rootfs文件

3. 将U盘插到主板上,重新给主板上电

4. 等待rootfs.img自动导出,此时系统会进入recovery模式,不会进入正常系统界面。导出完成后,系统会自动重启进入正常系统界面

5. U盘中的rootfs.img即为根文件系统分区镜像

在Windows电脑主机上制作完整固件

1. 解包完整固件update.img

  • 将下载的烧录包解压到当前文件夹,进入tools目录,将烧录工具windows.zip解压到当前文件夹,进入windows\RKDevTool\rockdev目录,双击执行nc-unpack.bat解包脚本,等待解包完成后各分区镜像保存在Output\Image目录中

Screenshot from 2023-02-01 13-45-54.png

2. 替换根文件系统分区镜像rootfs.img

  • 将导出的根文件系统分区镜像rootfs.img拷贝替换到Output\Image目录中

Screenshot from 2023-02-01 13-50-33.png

3. 打包完整固件update.img

  • 双击执行nc-pack.bat打包脚本,等待打包完成后完整固件update.img保存在Output目录中

Screenshot from 2023-02-01 13-56-02.png

在Windows电脑主机上烧录固件

安装驱动

将下载的烧录包解压到当前文件夹,进入tools目录,将烧录工具windows.zip解压到当前文件夹,进入windows目录,将驱动DriverAssitant_v*.zip解压到当前文件夹,进入DriverAssitant_v*目录,双击DriverInstall.exe安装驱动。 Screenshot from 2023-02-13 15-09-00.png

运行烧录工具

进入tools\windows\RKDevTool\RKDevTool_Release目录,双击RKDevTool.exe运行烧录工具。

连接烧录线

将主板和Windows电脑通过一根USB烧录线进行连接。

让主板进入烧录模式

在主板系统终端下执行命令:

reboot loader

主板会被烧录工具识别成一个LOADER设备或MASKROM设备。
Screenshot from 2023-02-13 16-37-25.png

烧录完整固件update.img

点击“升级固件” --> 点击“固件”并选中完整固件update.img --> 点击“升级”
Screenshot from 2023-02-13 16-46-50.png
烧录完成后,设备自动重启进入正常工作模式。

单独烧录内核分区镜像boot.img

在设备处于LOADER模式下,可以单独烧录boot分区镜像或rootfs等其他分区镜像,点击“设备分区表”可以看到设备的分区信息。
Screenshot from 2023-02-13 17-11-25.png

只勾选boot一栏 --> 确认地址与设备分区地址一致 --> 选中boot.img所在路径 --> 点击“执行”
Screenshot from 2023-02-13 17-13-03.png

烧录完成后,设备会自动重启或需手动断电重启,进入正常工作模式。

在Linux下打包完整固件

unpack.sh用于将完整固件解包成各个分区镜像;打包工具脚本mkupdate.sh用于将各分区镜像打包成一个完整的固件。

  • 将烧录、解包、打包工具linux.tar.gz解压到当前目录
tar xvf linux.tar.gz
  • 解包update.img
cd linux/Linux_Pack_Firmware/rockdev
ln -sfr ../../../../update.img update.img
./unpack.sh

完成后输出文件output/保存在当前目录下。
Screenshot from 2020-12-31 11-27-13.png

  • 根据需要替换指定分区镜像,比如替换根文件系统分区镜像output/Image/rootfs.img
  • 进行必要的移动拷贝,使用初始固件的分区参数、各分区镜像、打包配置文件
mv output/parameter.txt output/Image/
mv output/MiniLoaderAll.bin output/Image/
mv output/package-file .
ln -sfr output/Image/ Image
  • 根据芯片平台执行对应的打包脚本,完成后完整固件update.img保存在当前目录
./rk3399-mkupdate.sh

Screenshot from 2020-12-31 11-48-11.png

在Linux下烧录固件

烧录工具upgrade_tool可用于升级固件。

  • 连接好USB烧录线连接后,在主板的系统终端下执行如下命令,让主板进入烧录模式
reboot loader
  • 将烧录、解包、打包工具linux.tar.gz解压到当前目录,并进行简单设置
tar xvf linux.tar.gz
cd linux/Linux_Upgrade_Tool/Linux_Upgrade_Tool && chmod a+x upgrade_tool && sudo cp upgrade_tool /usr/local/bin
mkdir ~/.config/upgrade_tool/
cp config.ini ~/.config/upgrade_tool/
  • 烧录完整固件及各分区镜像的命令
sudo upgrade_tool uf update.img
  # 烧录完整固件
sudo upgrade_tool di -p parameter.txt
  # 烧录分区参数
sudo upgrade_tool di -uboot uboot.img
  # 烧录uboot分区镜像
sudo upgrade_tool di -b boot.img
  # 烧录内核分区镜像
sudo upgrade_tool di -rootfs rootfs.img
  # 烧录根文件系统分区镜像rootfs.img
sudo upgrade_tool di -r recovery.img
  # 烧录recovery镜像
sudo upgrade_tool di -userdata userdata.img
  # 烧录userdata分区镜像

QT开发

qt程序测试脚本

系统中添加了qt_test.sh和qt_test_touchscreen.sh测试脚本,在系统终端下直接运行:

qt_test.sh

基于libinput、tslib或evdev适配触摸屏运行qt程序:

qt_test_touchscreen.sh libinput
qt_test_touchscreen.sh tslib
qt_test_touchscreen.sh evdev

搭建qt开发环境

主机PC端环境为Ubuntu20.04,目标板系统为debian base系统,默认使用root用户自动登录,并支持root用户ssh远程登录,系统中移植了qt,支持linuxfb显示插件。 SDK与系统镜像一同发布,从相应的烧录包中获取SDK。SDK中包含交叉编译工具链、qmake、与目标板系统qt环境。解压SDK到任意目录$TOP_DIR(示例中以路径~/trash为例),并运行开发环境配置脚本

export TOP_DIR=~/trash
mkdir -p ~/trash
tar xpf host.tar.gz -C $TOP_DIR
cd $TOP_DIR/host
./relocate-sdk.sh

使用终端命令行编译运行qt程序

qt程序使用SDK中的qt5 examples例程,通过qmake、make命令进行编译:

export PATH=$TOP_DIR/host/bin:$PATH
cd $TOP_DIR/host/host/aarch64-buildroot-linux-gnu/sysroot/usr/lib/qt/examples/widgets/widgets/calculator
qmake
make

生成calculator程序,可通过scp拷贝到目标板中,并配置qt运行环境变量后运行:

scp calculator root@10.168.1.157:
ssh root@10.168.1.157
export LD_LIBRARY_PATH=/opt/data/target/usr/lib
export QT_QPA_PLATFORM_PLUGIN_PATH=/opt/data/target/usr/lib/qt/plugins

指定linuxfb显示插件运行程序:

./calculator -platform linuxfb
