5 Work with FriendlyWrt

5.1 Introduction to FriendlyWrt

FriendlyWrt is a customized system made by FriendlyElec based on an OpenWrt distribution. It is open source and well suitable for developing IoT applications, NAS applications etc.

5.2 First boot

For the first boot, the system needs to do the following initialization work：
1）Extended root file system
2）Initial setup（will execute /root/setup.sh)
So you need to wait for a while (about 2~3 minutes) to boot up for the first time, and then set FriendlyWrt, you can enter the ttyd terminal on the openwrt webpage, when the prompt is displayed as root@FriendlyWrt, it means the system has been initialized.

root@FriendlyWrt

5.3 Account & Password

The default password is password (empty password in some versions). Please set or change a safer password for web login and ssh login. It is recommended to complete this setting before connecting NanoPi-R2S to the Internet.

5.4 Login FriendlyWrt

Connect the PC to the LAN port of NanoPi-R2S. If your PC without a built-in ethernet port, connect the LAN port of the wireless AP to the LAN port of NanoPi-R2S, and then connect your PC to the wireless AP via WiFi , Enter the following URL on your PC's browser to access the admin page:

• http://friendlywrt/
• http://192.168.2.1/
• http://[fd00:ab:cd::1]

The above is the LAN port address of NanoPi-R2S. The IP address of the WAN port will be dynamically obtained from your main router through DHCP.

5.5 Recommended security settings

The following settings are highly recommended to complete before connecting NanoPi-R2S to the Internet。

• Set a secure password
• Only allow access to ssh from lan, change the port
• Check the firewall settings

• When doing secondary routing, the computer cannot connect to the Internet
  • If your main network is IPv4, and NanoPi-R2S works in IPv6, the computer may not be able to connect to the Internet. It is recommended to turn off IPv6 (the method is described later in this WiKi), or switch the main route to IPv6;
• If you have questions or have better suggestions, please send an email to techsupport@friendlyarm.com;

5.14 Use USB2LCD to view IP and temperature

Plug the USB2LCD module to the USB interface ofNanoPi-R2S and power on, the IP address and CPU temperature will be displayed on the LCD:

5.15 How to use USB WiFi

5.15.1 Check USB WiFi Device with Command Line Utility

(1) Click on "services>ttyd" to start the command line utility

(2) Make sure no USB devices are connected to your board and run the following command to check if any USB devices are connected or not

lsusb

(3) Connect a USB WiFi device to the board and run the command again

lsusb

You will see a new device is detected. In our test the device's ID was 0BDA:C811

(4) Type your device's ID (in our case it was "0BDA:C811" or "VID_0BDA&PID_C811") in a search engine and you may find a device that matches the ID. In our case the device we got was Realtek 8811CU.

5.15.2 Configure a USB WiFi Device as AP

(1) Connect a USB WiFi device to the NanoPi-R2S. We recommend you to use the following devices:

Note: devices that match these VID&PIDs would most likely work.
(2) Click on "System>Reboot" and reboot your NanoPi-R2S



(3) Click on "Network>Wireless" to enter the WiFi configuration page

(4) Click on "Edit" to edit the configuration

(5) On the "Interface Configuration" page you can set the WiFi mode and SSID, and then go to "Wireless Security" to change the password. By default the password is "password". After you make your changes click on "Save" to save



(6) After you change the settings you can use a smartphone or PC to search for WiFi

5.15.3 Common USB WiFi issues

1) It is recommended to plug in the usb wifi in the off state, then power it on, FriendlyWrt will automatically generate the configuration file /etc/config/wireless, if not, see if there is wlan0 by ifconfig -a, if there is no wlan0, usually there is no driver.
2) If ifconfig -a sees wlan0, but the hotspot is not working properly, try changing the channel and country code, an inappropriate country code can also cause the WiFi to not work.
3) Some USB WiFis (e.g. MTK MT7662) work in CD-ROM mode by default and need to be switched by usb_modeswitch, you can try to add usb_modeswitch configuration to the following directory: /etc/usb_modeswitch.d.

5.15.4 Change the default WiFi hotspot configuration

FriendlyWrt sets the country, hotspot name and other parameters for USB WiFi by default, with the aim of being as plug-and-play as possible, but this does not guarantee that all modules will be compatible with this setting, you can change these behaviors by modifying the following file：

/lib/wifi/mac80211.sh

5.16 Work with Docker Applications

5.16.1 Work with Docker: Install JellyFin

mkdir -p /jellyfin/config
mkdir -p /jellyfin/videos
docker run --restart=always -d -p 8096:8096 -v /jellyfin/config:/config -v /jellyfin/videos:/videos jellyfin/jellyfin:10.1.0-arm64 -name myjellyfin

After installation, visit port 8096 and here is what you would find:

5.16.2 Work with Docker: Install Personal Nextcloud

mkdir /nextcloud -p
docker run -d -p 8888:80  --name nextcloud  -v /nextcloud/:/var/www/html/ --restart=always --privileged=true  arm64v8/nextcloud

After installtion, visit port 8888.

5.16.3 Expand Docker Storage

• Stop docker service first:

/etc/init.d/dockerd stop

• Rename the original /opt directory, create an empty /opt directory:

mv /opt /opt-old && mkdir /opt

• Format your drive as ext4, and mount it to the /opt directory:

• Enter the command "mount | grep /opt" to check the mount status:

root@FriendlyWrt:~# mount | grep /opt
/dev/nvme0n1p1 on /opt type ext4 (rw,relatime)
root@FriendlyWrt:~#

• Copy the files from the original /opt directory to the new /opt directory:

cp -af /opt-old/* /opt/ && rm -rf /opt-old

• Reboot the device

reboot

• After reboot, go to the "Docker" -> "Overview" page, check the information in the "Docker Root Dir" line, you can see that the Docker space has been expanded:

5.16.4 Docker FAQ and solutions

5.16.4.1 Unable to access the network services provided by the Docker container

Solution:

• Go to the "Firewall" settings and set "Forwarding" to "Accept";
• Turn off "Software Offload";

5.17 Mount smbfs

mount -t cifs //192.168.1.10/shared /movie -o username=xxx,password=yyy,file_mode=0644

5.18 Use sdk to compile the package

5.18.1 Install the compilation environment

Download and run the following script on 64-bit Ubuntu (version 18.04+): How to setup the Compiling Environment on Ubuntu bionic

5.18.2 Download and decompress sdk from the network disk

The sdk is located in the toolchain directory of the network disk:

tar xvf openwrt-sdk-*-rockchip-armv8_gcc-11.2.0_musl.Linux-x86_64.tar.xz
# If the path is too long, it will cause some package compilation errors, so change the directory name here
mv openwrt-sdk-*-rockchip-armv8_gcc-11.2.0_musl.Linux-x86_64 sdk
cd sdk
./scripts/feeds update -a
./scripts/feeds install -a

5.18.3 Compile the package

download the source code of the example (a total of 3 examples are example1, example2, example3), and copy to the package directory:

git clone https://github.com/mwarning/openwrt-examples.git
cp -rf openwrt-examples/example* package/
rm -rf openwrt-examples/

Then enter the configuration menu through the following command:

make menuconfig

In the menu, select the following packages we want to compile (actually selected by default):

"Utilities" => "example1"
"Utilities" => "example3"
"Network" => "VPN" => "example2"

execute the following commands to compile the three software packages:

make package/example1/compile V=99
make package/example2/compile V=99
make package/example3/compile V=99

After the compilation is successful, you can find the ipk file in the bin directory, as shown below:

$ find ./bin -name example*.ipk
./bin/packages/aarch64_generic/base/example3_1.0.0-220420.38257_aarch64_generic.ipk
./bin/packages/aarch64_generic/base/example1_1.0.0-220420.38257_aarch64_generic.ipk
./bin/packages/aarch64_generic/base/example2_1.0.0-220420.38257_aarch64_generic.ipk

5.18.4 Install the ipk to NanoPi

You can use the scp command to upload the ipk file to NanoPi:

cd ./bin/packages/aarch64_generic/base/
scp example*.ipk root@192.168.2.1:/root/

Then use the opkg command to install them:

cd /root/
opkg install example3_1.0.0-220420.38257_aarch64_generic.ipk
opkg install example1_1.0.0-220420.38257_aarch64_generic.ipk
opkg install example2_1.0.0-220420.38257_aarch64_generic.ipk

5.19 Build FriendlyWrt using GitHub Actions

Please refre this link: https://github.com/friendlyarm/Actions-FriendlyWrt

6 Work with FriendlyCore

6.1 FriendlyCore User Account

• Non-root User:

   User Name: pi
   Password: pi

• Root:

   User Name: root
   Password: fa

6.2 Update Software Packages

$ sudo apt-get update

6.3 Setup Network Configurations

6.3.1 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 192.168.1.1

6.3.2 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

6.3.3 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.

6.4 Setup Wi-Fi

First, use the following command to check if Network-Manager is installed on your system:

which nmcli

If 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 YourWiFiPassword

Please 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

6.6 Build kernel-header deb package

Please refre to: https://github.com/friendlyarm/sd-fuse_rk3328/blob/master/test/test-build-kernel-header-deb.sh

6.7 Config status LEDs

First determine whether the system already exists the leds initialization service:

sudo systemctl status leds

If 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/lan_led/trigger
echo eth1 > /sys/class/leds/lan_led/device_name
echo 1 > /sys/class/leds/lan_led/link

6.8 Delete Qt5 and related files

Execute the following commands：

su root
cd /
rm -rf usr/local/Trolltech/Qt-5.10.0-rk64one usr/local/Trolltech/Qt-5.10.0-rk64one-sdk usr/bin/setqt5env* usr/bin/qt5demo etc/qt5

9.4.5 Running the build

9.4.5.1 Install to target board

This section applies to the following operating systems:

RK3328 uses GPT partitions by default, you can use the dd command, but be careful to choose the right output device:

• The SD/TF Card device node: /dev/mmcblk0
  
• The eMMC device node: /dev/mmcblk2
  

The following is an example of how to update the kernel to eMMC:
Use the 'parted' command to view the partition layout:

parted /dev/mmcblk2 print

Sample outputs:

Model: MMC BJTD4R (sd/mmc)
Disk /dev/mmcblk2: 31.3GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
 
Number  Start   End     Size    File system  Name      Flags
 1      8389kB  12.6MB  4194kB               uboot
 2      12.6MB  16.8MB  4194kB               trust
 3      16.8MB  21.0MB  4194kB               misc
 4      21.0MB  25.2MB  4194kB               dtbo
 5      25.2MB  41.9MB  16.8MB               resource
 6      41.9MB  83.9MB  41.9MB               kernel
 7      83.9MB  134MB   50.3MB               boot
 8      134MB   2500MB  2366MB  ext4         rootfs
 9      2500MB  31.3GB  28.8GB  ext4         userdata

as shown above, the resource partition is located at 5 and the kernel partition is located at 6. Use the dd command to write the resource.img and kernel.img files to these partitions, the commands are as follows:

dd if=resource.img of=/dev/mmcblk2p5 bs=1M
dd if=kernel.img of=/dev/mmcblk2p6 bs=1M

If you want to update u-boot:

dd if=uboot.img of=/dev/mmcblk2p1 bs=1M

To update new driver modules, copy the newly compiled driver modules to the appropriate directory under /lib/modules.

9.4.5.2 Packaging and creating an SD image

To create a new OS image file, you need to use the "sd-fuse" packaging tool.

"sd-fuse" is a collection of scripts that can be used to create bootable SD card images for FriendlyElec boards. Its main features include:

• Creation of root filesystem images from a directory
  
• Building of bootable SD card images
  
• Simple compilation of kernel, U-Boot, and third-party drivers
  

Please click on the following link to find out more:

9.4.5.3 USB flashing

9.4.5.3.1 Linux

Reboot the board and enter loader mode with the following command:

sudo reboot loader

To flash U-Boot and kernel using the "upgrade_tool_v2.17_for_linux" tool, please use the following command:

sudo upgrade_tool di -k kernel.img
sudo upgrade_tool di -re resource.img
sudo upgrade_tool di -u uboot.img
sudo upgrade_tool RD

Note: "upgrade_tool" is a command-line tool provided by Rockchip for Linux operating systems (Linux_Upgrade_Tool).

9.5 Build the code using scripts

9.5.1 Download scripts and image files

git clone https://github.com/friendlyarm/sd-fuse_rk3328.git -b kernel-4.19
cd sd-fuse_rk3328
wget http://112.124.9.243/dvdfiles/rk3328/images-for-eflasher/friendlycore-focal-arm64-images.tgz
tar xvzf friendlycore-focal-arm64-images.tgz

9.5.2 Compile the kernel

Download the kernel source code and compile it. the relevant image files in the friendlycore-focal-arm64 directory will be automatically updated, including the kernel modules in the file system:

git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-v4.19.y kernel-rk3328
KERNEL_SRC=$PWD/kernel-rk3328 ./build-kernel.sh friendlycore-focal-arm64

9.5.3 Compile the kernel headers

git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-v4.19.y kernel-rk3328
MK_HEADERS_DEB=1 BUILD_THIRD_PARTY_DRIVER=0 KERNEL_SRC=$PWD/kernel-rk3328 ./build-kernel.sh friendlycore-focal-arm64

9.5.4 Compile the uboot

Download the uboot source code and compile it. the relevant image files in the friendlycore-focal-arm64 directory will be automatically updated:

git clone https://github.com/friendlyarm/uboot-rockchip --depth 1 -b nanopi4-v2017.09
UBOOT_SRC=$PWD/uboot-rockchip ./build-uboot.sh friendlycore-focal-arm64

9.5.5 Generate new image

Repackage the image file in the friendlycore-focal-arm64 directory into sd card image:

./mk-sd-image.sh friendlycore-focal-arm64

After the command is completed, the image is in the out directory, you can use the dd command to make the SD boot card, for example:

dd if=out/rk3328-sd-friendlycore-focal-4.19-arm64-YYYYMMDD.img of=/dev/sdX bs=1M

10 Backup rootfs and create custom SD image (to burn your application into other boards)

10.1 Backup rootfs

Run the following commands on your target board. These commands will back up the entire root partition:

sudo passwd root
su root
cd /
tar --warning=no-file-changed -cvpzf /rootfs.tar.gz \
    --exclude=/rootfs.tar.gz --exclude=/var/lib/docker/runtimes \
    --exclude=/etc/firstuser --exclude=/etc/friendlyelec-release \
    --exclude=/usr/local/first_boot_flag --one-file-system /

Note: if there is a mounted directory on the system, an error message will appear at the end, which can be ignored.

10.2 Making a bootable SD card from a root filesystem

Run the following script on your Linux PC host, we'll only mention "ubuntu-noble-core-arm64 os" for brevity, but you can apply the same process for every linux OS.

su root
git clone https://github.com/friendlyarm/sd-fuse_rk3328 --single-branch -b kernel-6.1.y
cd sd-fuse_rk3328
tar xvzf /path/to/netdrive/03_Partition\ image\ files/ubuntu-noble-core-arm64-images.tgz
tar xvzf /path/to/netdrive/03_Partition\ image\ files/emmc-eflasher-images.tgz
scp pi@BOARDIP:/rootfs.tar.gz /rootfs.tar.gz
mkdir rootfs
tar xvzfp rootfs.tar.gz -C rootfs --numeric-owner --same-owner
./build-rootfs-img.sh rootfs ubuntu-noble-core-arm64
./mk-sd-image.sh ubuntu-noble-core-arm64
./mk-emmc-image.sh ubuntu-noble-core-arm64 autostart=yes
