9 Work with FriendlyCore
9.1 Introduction
FriendlyCore is a Ubuntu core based OS which doesn't have X Desktop. Its current version is 18.04
FriendlyCore targets enterprise users and is customized for industrial applications. FriendlyCore and Ubuntu base target different users. FriendlyCore has both a commandline utility and a two GUI utilities:
1)Qt 5.10.0 cuustomized for ROCKCHIP3399. It supports GPU and VPU acceleration and has modules like: QtQuick/QtWebEngine/QtMultimedia/WebGL and three display plug-ins:KMS, EGLFS and XCB;
2) Xorg system. It can run X11 applications and supports hardware acceleration;
FriendlyCore for RK3399 has the following features:
- supports FriendlyElec's 7"LCD with capacitive touch - HD702. If a board is connected to both an LCD and an HDMI monitor the LCD and the HDMI monitor can be set to display either differently or the same;
- supports Gstreamer 1.0 multi-media framework;
- supports hard encoding video playing with either commandline utility or Qt player;
- supports Qt5 WebGL;
- supports Qt5 VNC and runs a Qt application as a VNC Server allowing remote control;
- supports bluetooth. It has preinstalled bluez packages;
9.2 System Login
- If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
- If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will
You can use a USB to Serial on NanoPi-M4:
- FriendlyCore User Accounts:
Non-root User:
User Name: pi Password: pi
Root:
User Name: root Password: fa
The system is automatically logged in as "pi". You can do "sudo npi-config" to disable auto login.
- Update packages
$ sudo apt-get update
9.3 Configure System with npi-config
The npi-config is a commandline utility which can be used to initialize system configurations such as user password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following command to run this utility.
$ sudo npi-config
Here is how npi-config's GUI looks like:
9.4 Develop Qt Application
The Qt 5.10.0 FriendlyELEC ported for RK3399 supports the following plug-ins:KMS, EGLFS and XCB. All these three plug-ins support OpenGL ES and GPU hardware acceleration but in different ways:
- KMS - it calls Linux kernel's DRM interface to display
- EGLFS - it calls OpenGL ES interface to display
- XCB - it runs on X11 server and is integrated in X11 windows system
Three plug-ins support different Qt features and here is a table:
Plug-in OpenGL ES QtWebEngine QtMultimedia Video Playing with Hardware Decoding Different Display KMS Yes No Yes No Yes EGLFS Yes No Yes No No XCB Yes Yes Yes Yes Yes
We recommend to use KMS or XCB.
FriendlyCore has four scripts for setting Qt environmental variables for users and here is a table:
Script Comment /usr/bin/setqt5env-kms set kms' environmental variables /usr/bin/setqt5env-eglfs set eglfs' environmental variables /usr/bin/setqt5env-xcb set xcb's environmental variables /usr/bin/setqt5env-nogui set environmental variables for a system without a Qt GUI
For instance, if you want to use KMS to display you can run the following commands:
. setqt5env-kms
./apps
(Note:there is a space between '.' and 's')
9.4.1 Setup Qt Development Envronment
FriendlyELEC developed two methods for RK3399 to cross-compile a Qt program:
- 1:Use Docker. For more details you can refer to github :http://github.com/friendlyarm/friendlyelec-ubuntu18-docker
- 2:Setup a local cross-compiler. You need to run a Ubuntu 18.04 64-bit OS and you can refer to :How to Build and Install Qt Application for FriendlyELEC Boards/zh
9.4.2 Qt Demo
FriendlyCore has several Qt demo programs:
- Qt QML: CinematicExperience
CinematicExperience is a utility for selecting a video file and it is developed with Qt QML.
This demo uses Qt QML's various features and runs very smoothly on RK3399. This performance is achieved by hardware and software optimization.
You can start it in a commandline utility by running the following commands:
cd /opt/Qt5_CinematicExperience ./run.sh
- QQt WebEngine: web browser
Qt WebEngine uses Chromium and supports HTML5.
You can start it by running the following commands:
cd /opt/qt5-brower ./run.sh
Note:Qt WebEngine depends on the Xcb plug-in.
- Qt Different Display
This demo shows that when a board is connected to an HDMI monitor and an eDP LCD these two devices display differently. You can start it by running the following commands:
cd /opt/qt5-multi-screen-demo ./run.sh
- Qt Multimedia: qt5-player with hard decoding
The qt5-player works with Rockchip's gstreamer plug-in and supports 4K video playing. Since Rockchip's plug-in only supports output images to an X11 window the qt5-player needs to use XCB for display.
You can start the demo by running the following commands:
cd /opt/qt5-player ./run.sh
Here is what it looks like. You can set it to display in full-screen and adjust the voice's volume:
- Qt WebGL demo: nmapper
Qt WebGL allows you to remotely access a Qt program running on your board.
Before you run the demo you need to connect your board to the internet and run the following commands:
cd /opt/qt5-nmapper ./run-with-webgl.sh
You can open a browser on another device, type the IP address of your board on the browser's address bar, enter and you will be able to see a Qt GUI. Here is what it looks like:
- Qt VNC demo: Smart home applicance GUI
Qt VNC allows you to run a program as a VNC Server on your board and you can access the program from a VNC client on another device. This program can be developed with either QtWidgets or QML.
You can start it by running the following commands:
cd /opt/qt5-smarthome ./run-with-vnc.sh
Start a VNC viewer on a smart phone or mobile device and type your board's IP address and port number 5900. For instance if your board's IP address is 192.168.1.100 you can type "192.168.1.100:5900", enter and you will see the following GUI:
9.4.3 Play with Dual Cameras under Qt
This sample shows how to connect dual cameras to the board and play with them. Before run the sample make sure you connect dual cameras and an LCD to your board. In general popular UVC cameras should work however we suggest users use the following modules which we have tested:
Index Model 1 Logitech C270 2 Logitech C270i 3 Logitech C922 Pro
Run the following commands:
cd /opt/dual-camera ./run.sh
Here is what you expect to observe:
9.5 Setup Program to AutoRun
You can setup a program to autorun on system boot with npi-config:
sudo npi-config
Go to Boot Options -> Autologin -> Qt/Embedded, select Enable and reboot.
9.6 Extend TF Card's Section
When FriendlyCore is loaded the TF card's section will be automatically extended.You can check the section's size by running the following command:
$ df -h
9.7 Transfer files using Bluetooth
Take the example of transferring files to the mobile phone. First, set your mobile phone Bluetooth to detectable status, then execute the following command to start Bluetooth search.:
hcitool scan
Search results look like:
Scanning ... 2C:8A:72:1D:46:02 HTC6525LVW
This means that a mobile phone named HTC6525LVW is searched. We write down the MAC address in front of the phone name, and then use the sdptool command to view the Bluetooth service supported by the phone:
sdptool browser 2C:8A:72:1D:46:02
Note: Please replace the MAC address in the above command with the actual Bluetooth MAC address of the mobile phone.
This command will detail the protocols supported by Bluetooth for mobile phones. What we need to care about is a file transfer service called OBEX Object Push. Take the HTC6525LVW mobile phone as an example. The results are as follows:
Service Name: OBEX Object Push Service RecHandle: 0x1000b Service Class ID List: "OBEX Object Push" (0x1105) Protocol Descriptor List: "L2CAP" (0x0100) "RFCOMM" (0x0003) Channel: 12 "OBEX" (0x0008) Profile Descriptor List: "OBEX Object Push" (0x1105) Version: 0x0100
As can be seen from the above information, the channel used by the OBEX Object Push service of this mobile phone is 12, we need to pass it to the obexftp command, and finally the command to initiate the file transfer request is as follows:
obexftp --nopath --noconn --uuid none --bluetooth -b 2C:8A:72:1D:46:02 -B 12 -put example.jpg
Note: Please replace the MAC address, channel and file name in the above command with the actual one.
After executing the above commands, please pay attention to the screen of the mobile phone. The mobile phone will pop up a prompt for pairing and receiving files. After confirming, the file transfer will start.
Bluetooth FAQ:
1) Bluetooth device not found on the development board, try to open Bluetooth with the following command:
rfkill unblock 0
2) Prompt can not find the relevant command, you can try to install related software with the following command:
apt-get install bluetooth bluez obexftp openobex-apps python-gobject ussp-push
9.8 WiFi
For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:
Index Model 1 RTL8188CUS/8188EU 802.11n WLAN Adapter 2 RT2070 Wireless Adapter 3 RT2870/RT3070 Wireless Adapter 4 RTL8192CU Wireless Adapter 5 mi WiFi mt7601 6 5G USB WiFi RTL8821CU 7 5G USB WiFi RTL8812AU
You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:
- Change to root
$ su root
- Check device list
$ nmcli dev
Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.
- Start WiFi
$ nmcli r wifi on
- Scan Surrounding WiFi Sources
$ nmcli dev wifi
- Connect to a WiFi Source
$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0
The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.
For more details about NetworkManager refer to this link: Use NetworkManager to configure network settings
If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:
$ apt-get install linux-firmware
In general all WiFi drivers are located at the "/lib/firmware" directory.
9.9 Ethernet Connection
If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP refer to: Use NetworkManager to configure network settings。
9.10 WiringPi and Python Wrapper
9.11 Custom welcome message
The welcome message is printed from the script in this directory:
/etc/update-motd.d/
For example, to change the FriendlyELEC LOGO, you can change the file /etc/update-motd.d/10-header. For example, to change the LOGO to HELLO, you can change the following line:
TERM=linux toilet -f standard -F metal $BOARD_VENDOR
To:
TERM=linux toilet -f standard -F metal HELLO
9.12 Modify timezone
For exampe, change to Shanghai timezone:
sudo rm /etc/localtime sudo ln -ls /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
9.13 Select the system default audio device
You can set the system default audio device by following the steps below.
Use the following command to view all the sound card devices in the system (Note: different development boards will have different results):
pi@NanoPi:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: realtekrt5651co [realtek,rt5651-codec], device 0: ff880000.i2s-rt5651-aif1 rt5651-aif1-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: rockchiphdmi [rockchip,hdmi], device 0: ff8a0000.i2s-i2s-hifi i2s-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: ROCKCHIPSPDIF [ROCKCHIP,SPDIF], device 0: ff870000.spdif-dit-hifi dit-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0
As you can see, the following sound card devices are available on the hardware:
Sound card device Sound card number Description realtekrt5651co 0 Realtek sound card's default output interface (through 3.5mm jack interface) rockchiphdmi 1 HDMI ROCKCHIPSPDIF 2 SPDIF (Note: temporarily unavailable, because the hardware is not exported)...
To configure the audio output to the 3.5mm jack, modify the configuration file /etc/asound.conf and modify it to the following:
defaults.pcm.card 0 defaults.pcm.device 0
To configure to output audio to HDMI, change the defaults.pcm.card above to 1.
Note that some boards do not have a Realtek sound card (no 3.5mm jack interface), so the card number of the HDMI device will be 0, so the configuration should be based on the result of the aplay -l command.
9.14 Change the behavior of the PWM fan
By default, the speed of the fan is dynamically adjusted according to the CPU temperature. If you need to let the fan run, you can modify the script /usr/bin/start-rk3399-pwm-fan.sh to the following:
#!/bin/bash echo 0 > /sys/class/pwm/pwmchip1/export sleep 1 echo 0 > /sys/class/pwm/pwmchip1/pwm0/enable echo 50000 > /sys/class/pwm/pwmchip1/pwm0/period echo 1 > /sys/class/pwm/pwmchip1/pwm0/enable echo 45000 > /sys/class/pwm/pwmchip1/pwm0/duty_cycle
9.15 Run the X11 application
FriendlyCore system built-in lightweight Xorg,although there is no window manager, you can still run a single X-Windows application,For example, the program to run is ~/YourX11App,use the following command:
. /usr/bin/setqt5env-xcb startx ~/YourX11App -geometry 1280x800
Note that there is a space between "." and /usr/bin/setqt5env-xcb. In addition, the resolution after -geometry should be changed to the actual resolution of your screen.
9.16 Mpv hardware decoding video player
FriendlyCore comes pre-installed with the ffmpeg-based command line video player mpv, which also includes libmpv.
The mpv player supports Rockchip MPP video decoder, so it supports 4K hardware decoding. There are many parameters of mpv. In order to simplify the use, we provide a script start-mpv. After simplification, there is only one parameter: video file name, as follows:
start-mpv /home/pi/demo.mp4
It should be noted that the pi user needs to log in during playback, because there are no mpv related settings in other users' directories. Of course, you can copy one from the pi user directory. The mpv settings file is stored in the following path:
/home/pi/.config/mpv/mpv.conf
The contents of the mpv.conf file are as follows:
vo=gpu gpu-context=drm hwdec=rkmpp demuxer-max-bytes=41943040 demuxer-max-back-bytes=41943040 drm-osd-plane-id=1 drm-video-plane-id=0 audio-device=alsa/default:CARD=rockchiphdmi
These will be passed as parameters to mpv. When the value of hwdec is rkmpp, it means using hardware decoding, audio-device is used to specify the audio output device, and the default output is to HDMI. You can use the following command to query which audio devices are in the system:
mpv --audio-device=help
Another important parameter is drm-osd-size. When playing video in full screen, drm-osd-size is specified as the resolution of the screen. This parameter is automatically obtained by start-mpv and passed to mpv, start-mpv script will do one more important thing. It needs to ensure that the libmali library in the system uses the correct version, because mpv renders the image through gbm, so libmali.so needs to use this version: libmali-midgard-t86x -r14p0-gbm.so, which means that this version of mpv can only be used under FriendlyCore, can not be used under X11 Desktop.
Mpv official use guide:https://github.com/mpv-player/mpv/wiki
10 Features applicable to FriendlyDesktop and FriendlyCore
10.1 Using Camera on Linux (MIPI Camera OV13850 & OV4689, and webcam logitect C920)

10.3 Using ffmpeg (video hardware decoding)
Both FriendlyCore and FriendlyDesktop systems are built-in ffmpeg, with bin file, static libraries, and header files, all stored in the /usr/ffmpeg-rkmp directory.
ffmpeg supports the RockChip MPP video decoder, for details, please refer to: https://trac.ffmpeg.org/wiki/HWAccelIntro
Test the decoding performance of 4K video:
/usr/ffmpeg-rkmp/bin/ffmpeg -benchmark -loglevel 48 -vcodec h264_rkmpp -i 4K-Chimei-inn-60mbps.mp4 -map 0:v:0 -f null -
The results are shown below:
To play the video, you can use the ffmpeg-based player mpv. The 4K video used for the above test can be found in the test-video directory of the network disk. The network address is http://dl.friendlyelec.com/nanopct4.
11 Connect NVME SSD High Speed Hard Disk
11.1 Detection of SSD
root@FriendlyELEC:~# cat /proc/partitions major minor #blocks name 1 0 4096 ram0 259 0 125034840 nvme0n1
If there is a nvme0n1 device node it means an SSD is recognized.
11.2 Partition of SSD
To mount an SSD under Linux we re-partition it as one section by running the following command:
(echo g; echo n; echo p; echo 1; echo ""; echo ""; echo w; echo q) | fdisk /dev/nvme0n1
If you want to re-partition it to multiple sections you can run "fdisk /dev/nvme0n1". For more detail about this command refer to the fdisk's manual.
11.3 Format Section to EXT4
After an SSD is successfully partitioned you can check its sections by running "cat /proc/partitions". The /dev/nvme0n1p1 section is used to store data:
root@FriendlyELEC:~# cat /proc/partitions major minor #blocks name 1 0 4096 ram0 259 0 125034840 nvme0n1 259 2 125033816 nvme0n1p1
The following command formats a section to ext4:
mkfs.ext4 /dev/nvme0n1p1
11.4 Auto Mount SSD on System Startup
Before we mount an SSD's section you need to know its Block ID. You can check it by running "blkid":
blkid /dev/nvme0n1p1 /dev/nvme0n1p1: UUID="d15c4bbf-a6c3-486f-8f81-35a8dbd46057" TYPE="ext4" PARTUUID="887628f0-01"
Add a "Block ID" to "/etc/fstab" and here is what it looks like
UUID=<Block ID> /media/nvme ext4 defaults 0 0
You need to replace <Block ID> with the UUID obtained by running "blkid". To mount the SSD in our example we made the "/etc/fstab" file as follows:
UUID=d15c4bbf-a6c3-486f-8f81-35a8dbd46057 /media/nvme ext4 defaults 0 0
We want to mount an SSD to "/media/nvme" but this directory doesn't exist. Therefore we create it and change its access right by running the following commands:
mkdir -p /media/nvme chmod 777 /media/nvme
Run "mount" to check if the SSD is mounted successfully:
mount /media/nvme
You can reboot your board to check if your SSD will be automatically mounted:
reboot

14.14 Work with USB Camera to Take Pictures and Record Video
FriendlyELEC's Android system supports picture taking and video recording with a USB camera, Android's camera app has these functions. When you use the app to take pictures or record video you need to be aware of the following two things:
1) Make sure your camera's resolution works. We suggest you try a camera with a lower CIF resolution first. If it works you may switch to a camera with a higher resolution:
;
2)A USB camera cannot work simultaneously with a MIPI camera. Plug and play is not supporter for camera modules. After you connect a camera to a board you need to reboot your board to enable the camera.
Here are the camera modules we tested: Logitech C270 and LogitechC922 PRO
In our test the resolution was 1080P when we used a Logitech C922 PRO to take pictures or record video.
14.15 Using 4G Module EC20 on Android
14.15.1 Hardware Setup
Connect an EC20 module to a USB to miniPCIe board and connect the board to an ARM board's USB Host. Here is a hardware setup:
Power on the board and you will be able to surf the internet with the 4G module like using an Android phone.
14.15.2 Activate EC20's GPS Functions
By default GPS functions are disabled in Android. If GPS functions are enabled in Android but no GPS module is detected Android will continuously output log messages. After an EC20 module is connected you can enable GPS functions.
To enable the GPS functions open the "vendor/quectel/ec20/BoardConfigPartial.mk" file and change the following line:
BOARD_HAS_GPS := false
to
BOARD_HAS_GPS := true
and recompile Android。
14.16 Using SSD on Android
14.16.1 Step1: Format SSD as ext4
These steps need to be operated under the LINUX system.
For the convenience of operation, please switch to the root user with the following command on the terminal:
su -
The default password for the root user is fa.
14.16.1.1 Detection of SSD
root@FriendlyELEC:~# cat /proc/partitions major minor #blocks name 1 0 4096 ram0 259 0 125034840 nvme0n1
If there is a nvme0n1 device node it means an SSD is recognized.
14.16.1.2 Partition of SSD
To mount an SSD under Linux we re-partition it as one section by running the following command:
(echo o; echo n; echo p; echo 1; echo ""; echo ""; echo w; echo q) | fdisk /dev/nvme0n1
If you want to re-partition it to multiple sections you can run "fdisk /dev/nvme0n1". For more detail about this command refer to the fdisk's manual.
14.16.1.3 Format partition to EXT4
After an SSD is successfully partitioned you can check its partitions by running "cat /proc/partitions". The /dev/nvme0n1p1 partition is used to store data:
root@FriendlyELEC:~# cat /proc/partitions major minor #blocks name 1 0 4096 ram0 259 0 125034840 nvme0n1 259 2 125033816 nvme0n1p1
The following command formats a section to ext4:
mkfs.ext4 /dev/nvme0n1p1 -L SSD
14.16.2 Step2: Auto Mount SSD on Android System Startup
Android will automatically mount the SSD as an external storage device. No additional settings are required. Open the built-in Files application of Android and you can see that the SSD device is mounted:
third-party software can recognize SSDs normally.

16.4.7.1.1 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
16.4.7.1.2 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.
16.4.7.2 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 |

18.2 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
19 Configuring kernel command line parameters (only support for kernel4.4)
19.1 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.
19.2 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

20.2 Install Kernel Headers
sudo dpkg -i /opt/archives/linux-headers-*.deb
21 The usage of eMMC module
21.1 Install OS to eMMC
21.1.1 Option 1: Install OS via TF Card
This method firstly boots a mini Linux from a TF card and then automatically runs an EFlasher utility to install the OS to eMMC. You can connect your system to an HDMI monitor and watch its progress.
This is optional. You can watch its progress by observing its LEDs as well:
By default, flashing starts automatically upon power-up, so be sure to back up the data in eMMC. If you don't want it to start automatically, you can use image file with a filename containing the words 'multiple-os' and manually select the OS you want to flash on the interface.
21.1.1.1 Flash Official OS to eMMC
Follow the steps below:
- Get an SDHC card with a minimum capacity of 8G
- Visit download linkto download image files (in the "01_Official images/02_SD-to-eMMC images" directory) and win32diskimager tool (in the "05_Tools" directory);
- Extract the .gz format compressed file to get the .img format image file;
- Run the win32diskimager utility under Windows as administrator. On the utility's main window select your SD card's drive, the wanted image file and click on "write" to start flashing the SD card.
- Eject your SD card and insert it to NanoPi-M4’s microSD card slot.
- Turn on NanoPi-M4, it will boot from the SD card and automatically run EFlasher to install the OS to the board’s eMMC.
- After flashing is complete, eject the SD card from NanoPi-M4, NanoPi-M4 will automatically reboot and boot from eMMC.
21.1.1.2 Flash third party OS (Image file) to eMMC
- Auto Install (Default Behavior)
1) Download an “eflasher” firmware from network drive(in the "01_Official images/02_SD-to-eMMC images" directory), extract it and install it to a TF card ;
2) Eject and insert the TF card to your PC, after a “FriendlyARM” device shows up(Under Linux, it is a “FriendlyARM” directory), copy the image file ending with .raw or .gz into the directory (Note: if your file is in .img format, please rename it to .raw format).
3) Open the eflasher.conf file on the TF card, set “autoStart=” to the name of your image file, such as:
autoStart=openwrt-rockchip-armv8_nanopi-ext4-sysupgrade.img.gz
In addition to third-party image, official image files which with the '-sd-' word in the filename are also supported, for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz
4) Eject the TF card, insert the TF card to NanoPi-M4, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status.
21.1.2 Option 2: 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 (filename containing '-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.
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.
For official OS, you need select the file with the filename containing '-sd-', for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz, the compression file only supports the .gz format. If the file is too large, you can compress it into .gz format before uploading.
21.1.3 Option 3: Install OS via USB
21.1.3.1 Step 1: Install USB Driver and Tools/Utilities
Download a driver file DriverAssitant_v5.12.zip under the “tools” directory from network drive, extract and install it.
Under the same directory, download a utility RKDevTool_Release_v2.84.zip and extract it.
21.1.3.2 Step 2: Connect NanoPi-M4 to PC and Enter Installation Mode
Press and hold the “Mask” key, Use a USB cable, connect NanoPi-M4 to a PC,After the status LED has been on for at least 3 seconds, release the Mask key;
21.1.3.3 Step 3: Install image to eMMC
A firmware in general is packaged in either of the two options: the first is an whole image (ie, update.img) which is often offered by third party developers, the second is that an image is packaged and placed in multiple partition images. FriendlyElec offers an image in the latter option.
- Option 1: Install whole image (ie, update.img)
On a PC which has the extracted RKDevTool_Release_v2.84 utility, go to the RKDevTool_Release_v2.84 directory, run the RKDevTool.exe file. If everything works, you will see a “Found a new Maskrom device” message on the utility;
Go to “Upgrade Firmware(升级固件)”, click on “Firmware(固件)”, select your wanted image file, and click on “Upgrade(升级)” to install. After installation is done, your board will reboot automatically and load the system from eMMC;
- Option 2: Install OS that is packaged & placed in multiple partition images
Go to network drive to download your needed package and extract it (in the "01_Official images/03_USB upgrade images).
After it is extracted, you will see some utilities and a configuration file under the directory. double click on RKDevTool.exe, you will see a “Found a new Maskrom device” message on the utility. Click on the “Execute”, wait a moment and it will be installed. After installation is done your system will automatically reboot and load the system from eMMC.
