4.4.2 Flashing the OS to the microSD card

Follow the steps below:

• Get an 8G microSD card;
• Visit download linkto download image files (in the "01_Official images/01_SD card images" directory);
• Download the win32diskimager tool (in the "05_Tools" directory), or use your preferred tool;
• 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.
• Take out the SD and insert it to NanoPC-T6's microSD card slot;
• Power on NanoPC-T6 and it will be booted from your TF card, some models may require pressing the Power button to start;

4.4.3 Install OS to eMMC

4.4.3.1 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:

Progress	SYS LED(Red)
Power On	Solid On
System Boot	Slow Flashing
Installation in Progress	Fast Flashing
Installation Done	Slow Flashing

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.

4.4.3.1.1 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 NanoPC-T6’s microSD card slot.
• Turn on NanoPC-T6, 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 NanoPC-T6, NanoPC-T6 will automatically reboot and boot from eMMC.

4.4.3.1.2 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 NanoPC-T6, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status.

4.4.3.2 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.

4.4.3.3 Option 3: Install OS via USB

4.4.3.3.1 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.

4.4.3.3.2 Step 2: Connect NanoPC-T6 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 NanoPC-T6 to a PC;

4.4.3.3.3 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.

4.4.4 Installing the System to M.2 or USB Drive

You can use a TF card to boot the eFlasher system, allowing the boot and system to be installed on different storage devices. However, since the CPU doesn’t support booting directly from M.2 and USB devices, the system can be installed on M.2 and USB devices, but the boot must still be installed on eMMC or a TF card.
Steps are as follows:

• Prepare a TF card with a capacity of 32GB or larger.
• Visit [the download link here](http://download.friendlyelec.com/NanoPC-T6) to download the firmware file named XXXX-eflasher-multiple-os-YYYYMMDD-30g.img.gz (located in the “01_Official images/02_SD-to-eMMC images” directory).
• Flash the firmware to the TF card, connect the storage device you intend to use on NanoPC-T6, insert the TF card and power on, we need to perform the operations in the eFlasher GUI. If your NanoPC-T6 does not have a display interface, you can use VNC; refer to Using VNC to Operate eFlasher.
• In the eFlasher GUI, select the OS to install, and in the OS settings interface, choose the destination for boot installation (typically eMMC), then choose the destination for system installation (options include eMMC, M.2 hard drive, USB storage, etc.), as shown below:

• If no eMMC is available, the TF card can serve as the boot by inserting another TF card into the USB port via a USB card reader and selecting it as the boot destination, enabling booting from the TF card with the system stored on the M.2 or USB drive.
• After flashing, eject the SD card from NanoPC-T6. If booting from eMMC, NanoPC-T6 will automatically restart into the newly flashed system. If boot installation is on a TF card, power off, insert the boot TF card, and power on again.
• For a more detailed installation guide, please refer to this link.

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 NanoPC-T6. 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 NanoPC-T6

(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

7.3.1 USB connection

Please note: After turning on the ADB, the USB3 port will work in Device mode, if you need to connect a device such as a USB stick, you need to turn off the ADB and restart the board
In general, ADB is disabled by default, please follow the steps below to enable it:

• Connect your development board to your computer using a USB A-to-A data cable, referring to the figure below, be sure to connect it to the USB port closest to the edge:
  

7.3.2 For Android Tablet

• Go to Settings -> About tablet -> tap the "Build number" at the bottom of the screen 7 times in a row;
• Go to Settings -> System -> Advance -> Developer options, check USB-Debugging, and then reboot;
• To use ADB over the network, you need to connect to WiFi first, then enable Wireless debugging. In the prompt "Allow wireless debugging on the network", select "Always allow on this network", and then click "Allow".

7.3.3 For Android TV

• Click the Settings icon -> Device Preferences -> About -> tap the "Android TV OS build" at the bottom of the screen 7 times in a row;
• Click the Settings icon -> Device Preferences -> Developer options, check USB-Debugging, and then reboot;
• To use ADB over the network, on Android TV, which supports both WiFi and wired networks, enable network ADB by checking "Internet ADB" on the "Developer options" UI.

7.3.4 Using ADB

• Install ADB drivers and commands based on your operating system;
• Normally, the Android status bar will prompt "USB debugging connected", indicating that ADB has been enabled. Enter the following command on your computer to check the connection：

$ adb devices
List of devices attached
27f7a63caa3faf16	device

• Enter adb shell:

$ adb shell
nanopi3:/ $

7.3.5 Using ADB over the network

• On an Android Tablet, go to Settings -> System -> Advance -> Developer options, then click on Wireless debugging to view the IP address and port.
• The default network ADB port for Android TV is 5555.

Assuming the IP address and port displayed on the Wireless debugging interface are 192.168.1.167:45055, the ADB commands are as follows:

• To connect to the device:

$ adb connect 192.168.1.167:45055

connected to 192.168.1.167:45055

• To enter ADB shell:

$ adb shell
nanopi3:/ $

If there are multiple devices, use the -s parameter to specify the device's IP and port, as shown below:

$ adb -s 192.168.1.167:45055 shell
nanopi3:/ $

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 https://app.emotn.com/ui/ to download the APK, and then install it using ADB:

$ adb install com.oversea.aslauncher_1.0.9.0_5094.apk
Performing Streamed Install
Success

• 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
Success

• Then comes the critical step, you need to disable the native launcher using the following command:

$ adb shell pm disable-user --user 0 com.google.android.tvlauncher
Package com.google.android.tvlauncher new state: disabled-user

• Finally, restart the device to see the effect, the device should boot directly into Emotn UI:

$ adb shell reboot

• Root:

   User Name: root
   Password: fa

11.2 Update Software Packages

$ sudo apt-get update

11.3 Setup Network Configurations

11.3.1 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

The other ethernet port are set up with static IP addresses, as follows:
eth1: 192.168.2.1

11.3.2 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

11.3.3 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.

11.4 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

11.4.1 WiFi models supported

11.4.1.1 M.2 WiFi Module

• RTL8822CE

11.5 Install the kernel-header package

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

11.6 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/usr_led/trigger
echo eth0 > /sys/class/leds/usr_led/device_name
echo 1 > /sys/class/leds/usr_led/link

11.7 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

13.4.4 Running the build

13.4.4.1 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.

13.4.4.2 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
linux v6.1.y	sd-fuse_rk3588

13.4.4.3 USB flashing

13.4.4.3.1 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).

13.5 Build the code using scripts

13.6.6 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.

13.6.6.1 USB Flashing

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

13.6.6.2 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 NanoPC-T6 and re-flash;

13.6.7 Pack the new SD Image

git clone https://github.com/friendlyarm/sd-fuse_rk3588.git
SDFUSE=$PWD/sd-fuse_rk3588
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
 
cd $SDFUSE/
./mk-sd-image.sh android12
 
tar xvzf /path/to/netdrive/03_Partition\ image\ files/emmc-flasher-images.tgz
./mk-emmc-image.sh android12

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

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

14.1 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.

14.2 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_rk3588 --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
./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

15 Connect NVME SSD High Speed Hard Disk

15.1 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.

15.2 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.

15.3 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

15.4 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

16 Common Linux-based operating system operations

16.1 Using ADB on Linux Systems

16.1.1 Enabling ADB in Buildroot System

Enable on Startup

mv /etc/init.d/K50usbdevice.sh /etc/init.d/S50usbdevice.sh
reboot

Enable Temporarily

usbdevice-wrapper start

16.1.2 Enabling ADB in Ubuntu and Debian Systems

Enable on Startup

sudo systemctl enable usbdevice
sudo reboot

Enable Temporarily

usbdevice-wrapper start

16.1.3 How to Connect

When using ADB, the port connected to the computer is the same as the USB flashing port.

16.2 Install Kernel Headers

To install the .deb file located in the /opt/archives directory:

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

To download and update the kernel header files online:

wget http://112.124.9.243/archives/rk3588/linux-headers-$(uname -r)-latest.deb
sudo dpkg -i ./linux-headers-latest.deb

You can visit http://112.124.9.243/archives/rk3588 to see which kernel deb packages are available.

16.3 Update Kernel to Latest Version

This will update the kernel to the latest version and update the kernel and resource partitions, as well as the kernel modules:

wget http://112.124.9.243/archives/rk3588/linux-image-$(uname -r)-latest.deb
sudo dpkg -i ./linux-image-latest.deb
sudo reboot

16.4 Setting Kernel Boot Parameters (eMMC Only)

Flash the firmware file XXXX-eflasher-multiple-os-YYYYMMDD-30g.img.gz to a TF card, then insert the TF card into your computer. Windows will usually recognize the TF card partition automatically (formatted as exFAT). For Linux or Mac users, manually mount the first partition of the TF card. Assuming the TF card’s device name is /dev/sdX, mount /dev/sdX1.

Edit the info.conf configuration file in the OS directory on the TF card, adding the bootargs-ext parameter. For example:

bootargs-ext=rockchipdrm.fb_max_sz=2048

To remove a specified parameter, set it to empty. For example, to remove the userdata parameter:

bootargs-ext=userdata=

After editing, use this TF card to flash the system to eMMC.

To set kernel boot parameters during the creation of a mass production card, refer to the following script (example for RK3588): https://github.com/friendlyarm/sd-fuse_rk3588/blob/kernel-6.1.y/test/test-custom-bootargs.sh

17 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.

17.1 Windows Users

17.1.1 Download Required Files

• Get the necessary tools: Visit here, find RKDevTool_v3.19_for_window.zip and DriverAssitant_v5.12.zip in the 05_Tools directory, and download them to your local machine.
• Install Rockchip USB driver and RKDevTool: Extract DriverAssitant_v5.12.zip to install the Rockchip USB driver, and extract RKDevTool_v3.19_for_window.zip to obtain the Rockchip flashing tool RKDevTool.
• Get the loader: Visit here, enter the tools directory corresponding to your CPU model, and download MiniLoaderAll.bin.

17.1.2 Enter Maskrom Mode to Erase the Storage Device

• Connect NanoPC-T6 to your computer using a USB data cable.
• Start RKDevTool on your computer.
• Disconnect the power from NanoPC-T6, hold down the MASK button, connect the power, and release the button when you see Found One MASKROM Device displayed at the bottom of the interface, as shown below:

• Click the Advanced Function tab in the RKDevTool interface.
• In the Boot text box, select MiniLoaderAll.bin, then click the Download button.
• Select EMMC, click Switch Storage, then click the EraseAll button to erase the eMMC.

• (Optional): If your NanoPC-T6 has SPI Nor Flash, select SPINOR, click Switch Storage, then click the EraseAll button to erase the SPI Nor Flash.

• At this point, NanoPC-T6 is restored to its initial state and can be normally booted via SD card or eMMC.

17.2 Linux/Mac Users

17.2.1 Download the Required Files

• Get the necessary tools: Visit here and find upgrade_tool_v2.30_for_linux.tgz (or for Mac users, select upgrade_tool_v2.25_for_mac.tgz) in the 05_Tools directory and download it locally.
• Get the loader: Visit here, enter the tools directory corresponding to your CPU model, and download MiniLoaderAll.bin.

17.2.2 Installation for upgrade_tool

The following commands are for Linux, with only slight differences in file and directory names for Mac users:

tar xzf upgrade_tool_v2.30_for_linux.tgz
cd upgrade_tool_v2.30_for_linux
sudo cp upgrade_tool /usr/local/sbin/
sudo chmod 755 /usr/local/sbin/upgrade_tool

17.2.3 Enter Maskrom Mode to Erase the Storage Device

• Connect NanoPC-T6 to the computer using a USB data cable.
• Disconnect the power from NanoPC-T6, hold down the MASK button, connect the power, and release the button after 4 seconds.
• Check the connection with the following command:

upgrade_tool LD

A result similar to "DevNo=1 Vid=0x2207,Pid=0x350b,LocationID=13 Mode=Maskrom SerialNo=" indicates that the device has been detected.

• Erase the eMMC with the following command:

upgrade_tool EF MiniLoaderAll.bin

• (Optional): If your NanoPC-T6 has SPI Nor Flash, erase the SPI Nor Flash with the following commands:

upgrade_tool DB MiniLoaderAll.bin
upgrade_tool SSD   # Select 5, SPINOR
dd if=/dev/zero of=zero.img bs=1M count=16   # For 16M NOR FLASH
upgrade_tool WL 0 zero.img

• At this point, NanoPC-T6 has been restored to its initial state and can boot the system normally via SD card or eMMC.
