1.20 设置HDMI/DP屏幕分辨率
进入系统菜单 Perferences -> Monitor Settings界面进行设置即可。
推荐分辨率：1920x1080@60Hz
1.21 调节HDMI边界
打开命令行终端，输入命令进行操作，有几个注意事项：
1) 需要登录桌面才能操作，如果Desktop停留在Login是无法设置的;
2) 如果你是在 ssh 登录的终端，请使用与桌面登录相同的用户名，默认是 pi，不能使用root用户，同时，你需要赋值 DISPLAY 变量：
export DISPLAY=:0.0
1.21.1 查询显示器支持哪些分辨率
xrandr -q输出示例：
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 eDP-1 disconnected primary (normal left inverted right x axis y axis) HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1920x1080 60.00*+ 50.00 1280x720 60.00 50.00 720x576 50.00 720x480 59.94
1.21.2 设置分辨率
例如设置为 1920X1080@60Hz:
xrandr --output HDMI-1 --mode 1920x1080 --refresh 60
1.21.3 设节HDMI输出边界
For example, the transformation scaling horizontal coordinates by 0.8, vertical coordinates by 1.04 and moving the screen by 35 pixels right and 19 pixels down:
xrandr --output HDMI-1 --transform 0.80,0,-35,0,1.04,-19,0,0,1
1.21.4 开机自动调整
编辑~/.config/autostart/lxrandr-autostart.desktop，将完整的xrandr命令写入到Exec=开头的键中，如下所示：
[Desktop Entry] Type=Application Name=LXRandR autostart Comment=Start xrandr with settings done in LXRandR Exec=sh -c 'xrandr --output HDMI-1 --mode 1920x1080 --refresh 50 --transform 1.04,0,-35,0,1.05,-30,0,0,1' OnlyShowIn=LXDE
1.22 Chromium网页浏览器
1.22.1 GPU支持情况
系统预装的Chromium网页浏览器已经默认启用硬件加速，支持WebGL，可以通过输入网址 chrome://gpu 了解硬件加速情况，如下图所示：
1.22.2 VPU支持情况
在浏览器上播放一个视频,然后在命令行使用fuser查看mpp设备节点的使用情况来确认已经调用了vpu:
pi@FriendlyElec:~$ fuser /dev/mpp_service /dev/mpp_service: 3258
如果fuser命令没有内容输出, 则表示当前是软解.
1.22.3 查看支持的硬解格式
在浏览器地址栏输入 about://gpu，翻页到页面最底部，查看 "Video Acceleration Information" 表格;
播放一个视频后，再在浏览器地址栏输入 about://media-internals, 可以查看最近播放的视频是否启用了硬解;
1.23 测试mpp视频硬件编码
mpi_enc_test -w 1920 -h 1080 -t 7 -f 0 -o test.h264 -n 300 export XDG_RUNTIME_DIR=/run/user/0 ffplay test.h264
2 FriendlyCore的使用
2.1 FriendlyCore默认帐户
- 普通用户：
用户名: pi 密码: pi
- Root用户：
用户名: Root用户： 密码: fa
2.2 更新软件包
$ sudo apt-get update
2.3 配置网络
2.3.1 设置静态IP地址
默认已将 eth0 配置成 dhcp 自动获取IP地址，要更改配置，可以修改这个文件：
vi /etc/network/interfaces.d/eth0
比如修改成静态IP地址，如下所示：
auto eth0
iface eth0 inet static
address 192.168.1.231
netmask 255.255.255.0
gateway 192.168.1.1另外两个网口设置了静态IP地址, 设置如下:
eth1: 192.168.2.1
eth2: 192.168.3.1 (注:如果有第三个网口的话)
2.3.2 设置DNS
还需要修改如下文件加入DNS的配置：
vi /etc/systemd/resolved.conf
例如设置为192.168.1.1:
[Resolve] DNS=192.168.1.1
再用以下命令重新启动systemd-resolved服务：
sudo systemctl restart systemd-resolved.service sudo systemctl enable systemd-resolved.service
2.3.3 设置使用另一个网络接口
要配置另一个网口, 例如eth1，可以在 /etc/network/interfaces.d/ 下复制 eth0 成 eth1，然后编辑eth1, 把其中的eth0改为eth1, 根据需要指定网络配置:
cp /etc/network/interfaces.d/eth0 /etc/network/interfaces.d/eth1 vi /etc/network/interfaces.d/eth1
2.4 连接WiFi
先用以下命令检查一下系统是否有安装Network-Manager:
which nmcli如果有安装Network-Manager, 则参考此链接的方法连接WiFi: Use NetworkManager to configure network settings/zh, 如果没有安装, 则参考如下方法配置WiFi,
输入以下命令查询一下WiFi的网络接口，wlan开头的就是WiFi:
ifconfig -a
默认情况下是wlan0，在/etc/network/interfaces.d/目录下新建一个与网络接口同名的配置文件 ，以wlan0为例，用vi命令新建以下文件：
sudo vi /etc/network/interfaces.d/wlan0
wlan0文件的内容如下：
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid YourWiFiESSID
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk YourWiFiPassword其中，YourWiFiESSID和YourWiFiPassword请替换成你要连接的无线AP名称和密码, 保存文件后输入以下命令, 或者重启以应用配置:
sudo systemctl daemon-reload sudo systemctl restart networking
需要注意的是，如果你的SD卡在多个硬件上运行，WiFi的网络接口可能会被重命名为wlan1, wlan2等，你可以通过清空这个文件的内容并重启让它恢复为默认值：/etc/udev/rules.d/70-persistent-net.rules。
2.4.1 重点支持的WIFI型号
2.4.1.1 M.2 WiFi Module
- RTL8822CE
2.4.1.2 Usb Dongle

- MediaTek MT7662 (Vid: 0E8D, Pid: 7612) (测试样品:COMFAST CF-WU782AC V2)
2.5 安装内核头文件
sudo dpkg -i /opt/linux-headers-*.deb
2.6 配置状态灯
先确定一下系统是否已经存在leds初始化的服务:
sudo systemctl status leds如果已经存在leds服务, 则通过编辑如下文件改变状态灯的默认行为:
/etc/init.d/leds.sh
早期的固件由于没有leds服务, 需要参考以下指南手动配置状态灯, 首先, 设置开机自动加载以下内核模块:
modprobe ledtrig-netdev echo ledtrig-netdev > /etc/modules-load.d/ledtrig-netdev.conf
下面的脚本代码将状态灯与网卡相关联, 需要加入到开机自动运行的脚本中:
echo netdev > /sys/class/leds/wan_led/trigger echo eth0 > /sys/class/leds/wan_led/device_name echo 1 > /sys/class/leds/wan_led/link echo netdev > /sys/class/leds/lan1_led/trigger echo eth1 > /sys/class/leds/lan1_led/device_name echo 1 > /sys/class/leds/lan1_led/link echo netdev > /sys/class/leds/lan2_led/trigger echo eth2 > /sys/class/leds/lan2_led/device_name echo 1 > /sys/class/leds/lan2_led/link

4.3 Setup Network Configurations
4.3.1 Set static IP address
By default "eth0" is assigned an IP address obtained via dhcp. If you want to change the setting you need to change the following file:
vi /etc/network/interfaces.d/eth0
For example if you want to assign a static IP to it you can run the following commands:
auto eth0
iface eth0 inet static
address 192.168.1.231
netmask 255.255.255.0
gateway 192.168.1.1The other two ethernet ports are set up with static IP addresses, as follows:
eth1: 192.168.2.1
eth2: 192.168.3.1 (Note: if there are three network ports)
4.3.2 Set a DNS
You also need to modify the following file to add the DNS configuration:
vi /etc/systemd/resolved.conf
For example, set to 192.168.1.1:
[Resolve] DNS=192.168.1.1
Restart the systemd-resolved service with the following command:
sudo systemctl restart systemd-resolved.service sudo systemctl enable systemd-resolved.service
4.3.3 Set up to use another network interface
To change the setting of "eth1" you can add a new file similar to eth0's configuration file under the /etc/network/interfaces.d/ directory.
4.4 Setup Wi-Fi
First, use the following command to check if Network-Manager is installed on your system:
which nmcliIf you have installed it, refer to this link to connect to WiFi: Use NetworkManager to configure network settings, If you do not have Network-Manager installed on your system, please refer to the following method to configure WiFi,
By default the WiFi device is "wlan0". You need to create a configuration file under "/etc/network/interfaces.d/" for WiFi:
vi /etc/network/interfaces.d/wlan0
Here is a sample wlan0 file:
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid YourWiFiESSID
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk YourWiFiPasswordPlease replace "YourWiFiESSID" and "YourWiFiPassword" with your WiFiESSID and password. After save and close the file you can connect to your WiFi source by running the following command:
sudo systemctl daemon-reload sudo systemctl restart networking
After you power on your board it will automatically connect to your WiFi source.
Please note that if you use one TF card to boot multiple boards the WiFi device name will likely be named to "wlan1", "wlan2" and etc. You can reset it to "wlan0" by deleting the contents of the following file and reboot your board:
/etc/udev/rules.d/70-persistent-net.rules

4.5 Install the kernel-header package
sudo dpkg -i /opt/linux-headers-*.deb
4.6 Config status LEDs
First determine whether the system already exists the leds initialization service:
sudo systemctl status ledsIf the leds service already exists, change the default behavior of the LEDs by editing the following file:
/etc/init.d/leds.sh
Since there is no leds service in the early firmware, you need to refer to the following guide to manually configure the LEDs. First, set the following kernel modules to be automatically loaded at boot:
modprobe ledtrig-netdev echo ledtrig-netdev > /etc/modules-load.d/ledtrig-netdev.conf
Put the following into the autorun script to associate the status leds with the ethernet interface, and you can configure it to behave in other ways by referring to these content:
echo netdev > /sys/class/leds/wan_led/trigger echo eth0 > /sys/class/leds/wan_led/device_name echo 1 > /sys/class/leds/wan_led/link echo netdev > /sys/class/leds/lan1_led/trigger echo eth1 > /sys/class/leds/lan1_led/device_name echo 1 > /sys/class/leds/lan1_led/link echo netdev > /sys/class/leds/lan2_led/trigger echo eth2 > /sys/class/leds/lan2_led/device_name echo 1 > /sys/class/leds/lan2_led/link
