¶ 硬件链接
使用22针ffc平线将电路板连接到屏幕上，然后使用杜邦线将电路板连接到屏幕上，使用下图中的相应标签
连接后的成品如下图所示
¶ 打补丁
从上面的7英寸屏幕下载补丁文件。tinker edge r Android补丁文件位于“YYT-MIPI7LCD 2203/patch/tinker系列/百度网盘目录”。
安装补丁文件“0001-YYT-MIPI7LCD-Tinker-Edge-R-android9.patch 2 .在Android源代码根目录下，执行如下命令
git apply 0001-YYT-MIPI7LCD-Tinker-Edge-R-android9.patch
# 补丁完成后，检查是否成功，输入
git apply 0001-YYT-MIPI7LCD-Tinker-Edge-R-android9.patch --check
# 如果补丁不成功，选择“Force patch”并进入
git apply 0001-YYT-MIPI7LCD-Tinker-Edge-R-android90.patch --reject
# 如果没有，请选择手动修改或下载修改后的源代码
¶ 源代码编译
¶ 下载源代码
从百度网盘的tinker系列/tinkerR-Android9/目录里面下载
¶ 构建编译环境:
sudo apt-get update
sudo apt-get install git-core gitk git-gui gcc-arm-linux-gnueabihf gcc-armlinux-gnueabi device-tree-compiler gcc-aarch64-linux-gnu mtools parted \
libssl-dev fakeroot curl python make gcc lzop libc6:i386 lib32stdc++6 libncurses5:i386 libstdc++6:i386 bison libxml2-utils -y
sudo apt-get install liblz4-tool -y
pip install pycrypto
sudo apt-get install openjdk-8-jdk
¶ 安装驱动：
# Update the existing package list：
sudo apt update
# Use apt to install some packages that allow use over HTTPS:
sudo apt install apt-transport-https ca-certificates curl software-properties-common
# Then add the GPG key of the official Docker repository to your system:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# Add Docker repository to APT source:
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
# Update the package database with the Docker package in the newly added repo source:
sudo apt update
# Make sure you install from Docker repo and not the default Ubuntu repo:
apt-cache policy docker-ce
# Install Docker:
sudo apt install docker-ce
sudo groupadd docker
sudo usermod -aG docker $USER
sudo reboot
# Docker installed, check if it is running:
sudo systemctl status docker
¶ Install repo：
mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
git config --global user.email "test@asus.com"
git config --global user.name "test"
¶ 验证MD5码：
- The following two commands have the same output, indicating that the download is complete. Otherwise, you need to re-download the source code
md5sum tinkerR_Android9.tar.gz.0*
cat tinkerR_Android9.md5sum
¶ 解压:
cat tinkerR_Android9.tar.gz.0* > tinkerR_Android9.tar.gz
tar xzvf tinkerR_Android9.tar.gz
¶ 编译:
- After compiling, the image is generated in the rockdev directory
cd tinkerR-Android9
./docker_builder/docker-builder-run.sh
./build.sh
¶ 烧录镜像
¶ 上电
¶ Android固件操作
¶ 背光亮度控制
由adb登录Android后端，adb启动正在进行中，在http://wiki.smartfire.cn/Tinkerboard2/adb窗口启动终端。2 .执行以下命令，进入Android后端。
adb shell setprop persist.sys.root_access 3
adb root
adb remount
adb shell
# 这里的最大亮度是255。
echo 255 > /sys/class/backlight/backlight/brightness
