4.4.3 Install OS to eMMC 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. 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 CM3588’s microSD card slot.
  • Turn on CM3588, 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 CM3588, CM3588 will automatically reboot and boot from eMMC. 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:


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 CM3588, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status. 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. Option 3: Install OS via USB Step 1: Install USB Driver and Tools/Utilities

Download a driver file under the “tools” directory from network drive, extract and install it.
Under the same directory, download a utility and extract it. Step 2: Connect CM3588 to PC and Enter Installation Mode

1) Press and hold the “Mask” key, power on the board. After the status LED has been on for at least 3 seconds, release the Mask key;
2) Use a USB C-to-A cable, connect CM3588 to a PC;
Cm3588-usbflash.jpg 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.

7.4 How to Change Default Launcher in Android TV

  • Refer to the previous section to enable adb
  • For example, install the third-party launcher Emotn UI via APK, visit the website to download the APK, and then install it using ADB:
$ adb install com.oversea.aslauncher_1.0.9.0_5094.apk
Performing Streamed Install
  • After the installation is complete, launch it, and then enter the following ADB command to obtain its package name:
$ adb shell dumpsys window | grep mCurrentFocus
mCurrentFocus=Window{7a950fb u0 com.oversea.aslauncher/com.oversea.aslauncher.ui.main.MainActivity}
  • As you can see, the package name of Emotn UI is com.oversea.aslauncher, set it as the default launcher:
$ adb shell pm set-home-activity com.oversea.aslauncher
  • Then comes the critical step, you need to disable the native launcher using the following command:
$ adb shell pm disable-user --user 0
Package new state: disabled-user
  • Finally, restart the device to see the effect, the device should boot directly into Emotn UI:
$ adb shell reboot
  • From now on, if you want to install another launcher, you can switch between them through the GUI. for example, after installing FLauncher, you can enter the following settings interface to set FLauncher as the default launcher: Settings -> Device Preferences -> Advanced setting -> Default Launcher:


7.5 Wired networks on Android

  • Any network port can connect to the network via DHCP
  • If you want to configure a static IP, only eth0 interface is supported
  • Some applications may have compatibility issues and report no network connection error, but the network is actually connected

  • Root:
   User Name: root
   Password: fa

9.2 Update Software Packages

$ sudo apt-get update

9.3 Setup Network Configurations

9.3.1 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

9.3.2 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


Restart the systemd-resolved service with the following command:

sudo systemctl restart systemd-resolved.service
sudo systemctl enable systemd-resolved.service

9.3.3 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.

9.4 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

9.5 Install the kernel-header package

sudo dpkg -i /opt/linux-headers-*.deb

Run your build:
Please refre to #Running the build

10.4.4 Running the build Install to target board

RK3588 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

Use the 'parted' command to view the partition layout:

parted /dev/mmcblk2 print

Sample outputs:

Model: MMC A3A551 (sd/mmc)
Disk /dev/mmcblk2: 31.0GB
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               misc
 3      16.8MB  21.0MB  4194kB               dtbo
 4      21.0MB  37.7MB  16.8MB               resource
 5      37.7MB  79.7MB  41.9MB               kernel
 6      79.7MB  113MB   33.6MB               boot
 7      113MB   147MB   33.6MB               recovery
 8      147MB   31.0GB  30.9GB  ext4         rootfs

as shown above, the resource partition is located at 4 and the kernel partition is located at 5. 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/mmcblk2p4 bs=1M
dd if=kernel.img of=/dev/mmcblk2p5 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. 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
linux v6.1.y sd-fuse_rk3588 USB flashing 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).

10.5 Build the code using scripts

10.5.1 Download scripts and image files

git clone --single-branch -b kernel-6.1.y
cd sd-fuse_rk3588
tar xvzf /path/to/netdrive/03_Partition\ image\ files/friendlycore-focal-arm64-images.tgz

10.5.2 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 --depth 1 -b nanopi6-v6.1.y kernel-rk3588
KERNEL_SRC=$PWD/kernel-rk3588 ./ friendlycore-focal-arm64

10.5.3 Compile the kernel headers

git clone --depth 1 -b nanopi6-v6.1.y kernel-rk3588
MK_HEADERS_DEB=1 BUILD_THIRD_PARTY_DRIVER=0 KERNEL_SRC=$PWD/kernel-rk3588 ./ friendlycore-focal-arm64

10.5.4 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 --depth 1 -b nanopi6-v2017.09
UBOOT_SRC=$PWD/uboot-rockchip ./ friendlycore-focal-arm64

10.5.5 Generate new image

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

./ 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/rk3588-sd-friendlycore-focal-5.10-arm64-YYYYMMDD.img of=/dev/sdX bs=1M

10.6 Building AOSP from source

10.6.1 Hardware and Software Requirements

  • Your computer should have at least 16GB of RAM and 300GB of disk space. We recommend using a machine with 32GB of RAM and a large-capacity, high-speed SSD, and we do not recommend using virtual machines.
  • If you encounter compilation errors, they may be caused by problems with the compilation environment. We recommend using the following Docker container for compilation: docker-cross-compiler-novnc.

10.6.6 Running your AOSP build

After the Android compilation is completed, the image file will be stored in the rockdev/Image-aosp_nanopi3 subdirectory of the Android source code directory. USB Flashing

Use the rockchip tool to flash the following file: rockdev/Image-aosp_nanopi3/update.img SD-to-eMMC Flashing

Refer to the following steps:
1) Insert the SD card of the eflasher system into the host;
2) Copy the files in the rockdev/Image-aosp_nanopi3 directory to the android12 or androidtv directory in the FRIENDLYARM partition of the SD card:

sudo cp -af parameter.txt config.cfg MiniLoaderAll.bin uboot.img \
    dtbo.img vbmeta.img boot.img recovery.img \
    misc.img pcba_small_misc.img pcba_whole_misc.img \
    baseparameter.img super.img /media/$USER/FriendlyARM/android12

3) Insert the SD card into CM3588 and re-flash;

10.6.7 Pack the new SD Image

git clone
mkdir $SDFUSE/android12
cd /path/to/rk35xx-android12/rockdev/Image-aosp_nanopi3
cp -af parameter.txt config.cfg MiniLoaderAll.bin uboot.img \
    dtbo.img vbmeta.img boot.img recovery.img \
    misc.img pcba_small_misc.img pcba_whole_misc.img \
    baseparameter.img super.img $SDFUSE/android12
./ android12
tar xvzf /path/to/netdrive/03_Partition\ image\ files/emmc-flasher-images.tgz
./ android12

For more information, please refer to #Packaging and creating an SD image

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

11.1 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.

11.2 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 --single-branch -b kernel-6.1.y
cd sd-fuse_rk3588
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
./ rootfs debian-bullseye-desktop-arm64
./ debian-bullseye-desktop-arm64
./ debian-bullseye-desktop-arm64 autostart=yes

12 Connect NVME SSD High Speed Hard Disk

12.1 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.

12.2 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.

12.3 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

12.4 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:
