  • Power on NanoPi-R4SE and it will be booted from your TF card;

4.4.2 Install OS to eMMC

4.4.2.1 Option 1: Install OS on Web Page

Get a TF card which has been installed with FriendlyWrt, log in FriendlyWrt on the web page, click on “System” ->”eMMC Tools”. Click on “Select file” to select your wanted image file, either an official image (the name might start with “rk3399-sd”) or a third party image. The file should be a “.gz” or “.img” file.
After a file is selected, click on “Upload and Write” to start installing an OS.
Friendlywrt-emmctools2-en.png
After installation is done, eject the SD card, the system will automatically reboot and load the OS from eMMC. After the OS begins to load, if the system LED is flashing and the network LED is on, it means the the OS has loaded successfully. If the OS is FriendlyWrt, you can click on “Go to Homepage” to enter the homepage.
Note that if you are burning the FriendlyElec firmware, you need to use an image file with the "-sd-" file name, similar to the one below:

rk3399-sd-friendlywrt-21.02-YYYYMMDD.img.gz
rk3399-sd-friendlywrt-21.02-docker-YYYYMMDD.img.gz
rk3399-sd-friendlywrt-23.05-YYYYMMDD.img.gz
rk3399-sd-friendlywrt-23.05-docker-YYYYMMDD.img.gz

If the file is in 7z, zip or rar format, you will need to extract it first. If the file is too large to write, you can compress it into .gz format and try again.

4.4.2.2 Option 2: Install OS via TF Card
4.4.2.2.1 Install OS to eMMC

5.15 How to Control Fan Speed for Cooling

（Note: The contents of this section are based on firmware released after 2021/08/31, kernel version kernel 5.10.xyz）

  • The default behavior of the current PWM fan is: after a short wait (about 20 seconds) for power on, the fan will first work automatically for about 5 seconds, after which the behavior is driven by the kernel, which decides the fan on/off and the speed according to the CPU temperature.
  • The behavior of the fan can be changed by modifying the following script: /usr/bin/fa-fancontrol.sh. For example, to change the CPU temperature when the fan starts working, you can change the following two lines:
echo 50000 > trip_point_3_temp  # Indicates that the fan starts working at the lowest speed when the CPU temperature reaches 50 degrees
echo 55000 > trip_point_4_temp  # Indicates that when the CPU temperature reaches 55 degrees, the fan rises to the second gear and above and automatically adjusts to the highest gear (4th gear) or reduces the speed according to the CPU cooling situation

As shown below, the cooling-levels define 4 levels, with 0 being off and the highest level being 255: 

	fan: pwm-fan {
 		compatible = "pwm-fan";
-		/* FIXME: adjust leveles for the connected fan */
-		cooling-levels = <0 12 18 255>;
+		cooling-levels = <0 18 102 170 255>;
  • If you are using kernel version 4.19.xyz, the fan is operated by PWM at the application level to achieve temperature control, the above content is not applicable, you need to modify this script: 
/usr/bin/fa-fancontrol-direct.sh


5.16 How to use USB WiFi

5.16.1 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.

5.16.2 Configure a USB WiFi Device as AP

(1) Connect a USB WiFi device to the NanoPi-R4SE. We recommend you to use the following devices:
R2swrt+usbwifi-20210831.jpg
Note: devices that match these VID&PIDs would most likely work.
(2) Click on "System>Reboot" and reboot your NanoPi-R4SE

(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

5.16.3 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.

5.16.4 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

5.17 Work with Docker Applications

5.17.1 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:

After installtion, visit port 8888.

5.17.3 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:

Friendlywrt mount nvme opt-en.jpg

  • 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:

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

5.19.4 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

5.20 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_rk3399/blob/kernel-5.15.y/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

10.4.7 Running the build

10.4.7.1 Install to target board
10.4.7.1.1 MBR partition

This section applies to the following operating systems:

lubuntu eflasher friendlydesktop-arm64 friendlycore-arm64

The MBR partitioning is only used by the Linux v4.4 kernel. You can check the partition layout by clicking on this link: partmap. To write an image file, you can use the dd command. For example, in the parameter.template file, "0x00014000@0x00014000(kernel)" specifies that the kernel partition starts at 0x00014000, which is equivalent to 81920 in decimal. Therefore, the dd command should be as follows: 

dd if=kernel.img of=/dev/mmcblk0 seek=81920
10.4.7.1.2 GPT partition

This section applies to the following operating systems:

ubuntu-focal-desktop-arm64 debian-bookworm-core-arm64 debian-bullseye-desktop-arm64 debian-bullseye-minimal-arm64
friendlycore-focal-arm64 ubuntu-noble-core-arm64 friendlywrt21-kernel4 buildroot
friendlywrt21 friendlywrt21-docker friendlywrt23 friendlywrt23-docker

The OS uses GPT partitions by default which is using the Linux v4.19 and Linux v5.15 kernel, 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.

10.4.7.2 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:

Kernel version Packaging Tool

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

12.1 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.

12.2 Making a bootable SD card from a root filesystem

Run the following script on your Linux PC host, we'll only mention "debian-bullseye-desktop-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_rk3399 --single-branch -b kernel-4.19
cd sd-fuse_rk3399
tar xvzf /path/to/netdrive/03_Partition\ image\ files/debian-bullseye-desktop-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 debian-bullseye-desktop-arm64
./mk-sd-image.sh debian-bullseye-desktop-arm64
./mk-emmc-image.sh debian-bullseye-desktop-arm64 autostart=yes

13 Configuring kernel command line parameters (only support for kernel4.4)

13.1 eMMC Boot

Here are the steps:
Make an eflahser bootable SD card (use the firmware file starting with rk3xxxx-eflasher-)，
Insert the SD card into your computer, go to the SD card's OS-related directory, and edit the file parameter.txt, which is a text file containing command-line parameters，
Then boot from the SD card and burn the system to the eMMC.

13.2 SD Boot

To modify the command line parameters of the SD card, you need to repackage the SD card image file,
you can use the sd-fuse script we provide to assist packaging: 

git clone https://github.com/friendlyarm/sd-fuse_rk3399.git -b master --single-branch
cd sd-fuse_rk3399
tar xvzf /path/to/netdrive/03_Partition\ image\ files/friendlydesktop-arm64-images.tgz
tar xvzf /path/to/netdrive/03_Partition\ image\ files/emmc-flasher-images.tgz
vim friendlydesktop-arm64/parameter.txt   # Edit command-line parameters
./mk-sd-image.sh friendlydesktop-arm64    # Repackage sd image file
./mk-emmc-image.sh friendlydesktop-arm64  # Repackage sd-to-emmc image file

14 Unbricking Method

If the ROM is not installed correctly, causing the development board to become bricked, and you might not have the opportunity to reinstall the ROM via an SD card, you need to enter Maskrom mode to unbrick it by erasing the storage device.

14.1 Windows Users

14.1.1 Download Required Files
