5 Get Started
5.1 Essentials You Need
Before starting to use your NanoPC-T4 get the following items ready
- NanoPC-T4
- Type-C cable
- TF Card: Class 10 or Above, minimum 8GB SDHC
- USB to serial adapter(optinal, for debugging or access from PC host)
- A DC 12V/2A power is a must
- HDMI monitor or LCD
- USB keyboard, mouse and possible a USB hub(or a TTL to serial board)
- A host computer running Ubuntu 16.04 64 bit system or Windows 7
5.2 Debug with Serial Pins
If you want to get T4's boot messages or access T4 remotely you can operate it by using its serial pins.
- Get a USB to serial adapter and connect it to a T4:
Pin# T4's Serial Pins USB to Serial Board 1 GND GND 2 VCC5V0_SYS NC (Not Connected)
Note: if this is a FriendlyElec's Matrix USB2UART you need to turn off the "5V ON/OFF"3 UART2DBG_TX RX 4 UART2DBG_RX TX
- If you connect a USB to Serial adapter to a PC running Linux it will usually be recognized as ttyUSB0. To find out the device name, run the following commands:
dmesg | grep ttyUSB ls -l /dev/ttyUSB*
- On a PC running Linux install and run minicom, and set its configuration as follows(1500000 Bps, 8N1, N)
sudo apt-get install minicom minicom -s
Note: RK3399's debug serial interface's default baud rate is 1500000. Some adapter may not be able to run at this rate. You need to find a working adapter.
5.3 Flash Image to eMMC
As for a RK3399 based ARM board developed by FriendlyELEC there are three ways to flash an image to eMMC:
- Use eflasher to make a bootable SD card and flash an image to eMMC with this card
- Use a Windows' utility "AndroidTool_Release_v2.42" provided by Rockchip to flash an image to eMMC with a Type-C cable
- Use a Linux utility Linux_Upgrade_Tool_1.27 provided by Rockchip to flash an image to eMMC with a Type-C cable
If you are not familiar with the two utilities provided by Rockchip or you don't have a Type-C cable we suggest you try the first method.
5.3.1 Download Image and Utilities
Visit download link to download image files and utilities.
| Image Files | |
| rk3399-eflasher-YYYYMMDD-full.img.zip | Image for SD card, which is flashed to an SD card. This card can then be used to flash an Android or Lubuntu image to eMMC |
| android-nougat-images.tgz | Android 7.1.2 Image |
| lubuntu-desktop-images.tgz | Lubuntu desktop image with X Window |
| Flash Utility: | |
| win32diskimager.rar | Windows utility. Under Linux users can use "dd" |
| AndroidTool_Release_v2.42.7z | A Windows utility provided by Rockchip for flashing an image to eMMC. It needs to be used together with a Type-C cable. |
| DriverAssitant_v4.5.tgz | A Windows USB driver provided by Rockchip. When you flash an image with AndroidTool you need to install this driver. |
| Linux_Upgrade_Tool_1.27.rar | A Linux utility provided by Rockchip for flashing an image to eMMC. It needs to be used together with a Type-C cable. |
5.3.2 Flash Image to eMMC with eflasher
- Get a 8G SDHC card;
- Download the "rk3399-eflasher-YYYYMMDD-full.img.zip" and "win32diskimager" and extract them on a Windows PC;
- Run the "win32diskimager" utility as administrator, select your TF card, wanted file and click on "Write" to start flash the image to your TF card;
- After it is done take out the TF card and insert it to your T4's microSD slot;
- Connect a 12V/2A DC power cord and an HDMI monitor to your T4, press and hold the Power button for at least 1.5 seconds and you will see the PWR led is on and the image on SD card is booted. Around 15 seconds later the HDMI monitor will display a Window;
- Select your wanted OS with a USB mouse and click on "Next" to continue;
- After flashing is done press and release the Power button to shut down the system. After the PWR is off take out the TF card. Press and hold the Power button for at least 1.5 seconds the image will be booted from eMMC.
5.3.3 Flash Image to eMMC with AndroidTool
- Download DriverAssitant_v4.5.tgz, extract it and install it on a Windows PC;
- Download your wanted image from images-for-eflasher and extract it. For example the image for Android 7 is "android-nougat-images.tgz". You can ignore the "idbloader.img" and "info.conf" files.
- Download AndroidTool_Release_v2.42.7z, extract it and run AndroidTool.exe as administrator.
- Import a parameter.txt for sections and configure a file for each section if needed:
- Connect a 12V/2A DC power cord and an HDMI monitor to your T4, connect your T4 to a PC with a Type-C cable. Press and hold the Recovery button and the Power button for at least 1.5 seconds AndroidTools will prompt that a LOADER device is found
a) If eMMC hasn't been flashed with an image or the image inside is removed or damaged this eMMC will be recognized as a MASKROM device; b) You can hold both the BOOT button and the Power button for at least 5 seconds to force the board to enter the MASKROM mode; c) If your system shows "no device is found" you need to check if you have installed a driver or if your Type-C cable works and then try it again; d) If your system is booted successfully you can run "reboot loader" on your board via adb or SSH and force your board to enter the LOADER mode.
- Click on "Run" to download your wanted image to eMMC. A while later after the image is flashed successfully your board will be rebooted automatically.
5.3.4 Flash Image to eMMC with Linux_Upgrade_Tool
This is a Linux utility provided by Rockchip. You need to use it together with a Type-C cable. It can be used to install an image to eMMC, delete image files from eMMC, read from and write to eMMC and etc.
- Install upgrade_tool: download Linux_Upgrade_Tool_1.27.rar, extract it and set upgrade_tool's access right
sudo cp upgrade_tool /usr/local/sbin sudo chown root:root /usr/local/sbin/upgrade_tool sudo chmod 0755 /usr/local/sbin/upgrade_tool
- Download your wanted image from images-for-eflasher and extract it. For example the image for Lubuntu is "lubuntu-desktop-images.tgz".
- Refer to the steps in "Flash Image to eMMC with AndroidTool" to boot your board and force it to enter either LOADER or MASKROM mode;
- Run the following commands to flash Lubuntu to eMMC and reboot your board:
sudo upgrade_tool ul MiniLoaderAll.bin sudo upgrade_tool di -p parameter.txt sudo upgrade_tool di uboot uboot.img sudo upgrade_tool di trust trust.img sudo upgrade_tool di resource resource.img sudo upgrade_tool di kernel kernel.img sudo upgrade_tool di boot boot.img sudo upgrade_tool di rootfs rootfs.img sudo upgrade_tool RD
- If you want to flash Android 7 to eMMC you can download and extract its image file and run the following commands:
sudo upgrade_tool ul MiniLoaderAll.bin sudo upgrade_tool di -p parameter.txt sudo upgrade_tool di uboot uboot.img sudo upgrade_tool di trust trust.img sudo upgrade_tool di misc misc.img sudo upgrade_tool di resource resource.img sudo upgrade_tool di kernel kernel.img sudo upgrade_tool di boot boot.img sudo upgrade_tool di recovery recovery.img sudo upgrade_tool di system system.img sudo upgrade_tool RD
If the image's MiniLoaderAll.bin has a different version or the image you want to flash to eMMC is different from the image that already exists in eMMC you need to delete the image file in eMMC and then flash your new image to it.
Boot your board and enter the LOADER mode, run the following commands to delete the image in eMMC. If a prompt shows "Download Boot Start" and it lasts for 10 seconds you need to press the Reset button and run the following commands again.
sudo upgrade_tool EF MiniLoaderAll.binIf it succeeds you will see a prompt showing "Erase flash ok."

The Lubuntu Desktop has been optimized for adopting Mali GPU. It has driver support for X.org and supports Hardware Cursor, OpenGL acceleration and etc.
7.2 Lubuntu Default User Account
Non-root User:
User Name: pi Password: pi
Root:
User Name: root Password: fa
7.3 OpenGL ES
Open a command line utility and run the following command:
glmark2-es2
7.4 Video Playing with Hardware Decoding
Open a command line utility and run the following command:
gst-player.sh
A video window will be displayed with Overlay and voices will be output to the audio interface. You can run "which gst-player.sh" to locate the script and customize video playing.
7.5 Connect USB Camera to T4
Connect a USB camera (e.g. Logitech C270) to T4, start Lubuntu, enter the "Other" menu, start "xawtv" and you will be able to preview with the camera.
7.6 5G WiFi
Click on the network icon on top right of the Lubuntu GUI, select a WiFi hotspot and proceed with prompts.
7.7 Connect NVME SSD High Speed Hard Disk to T4
Connect a NVME SSD hard disk to NanoPC-T4's M.2 interface, initialize and automatically mount the SSD by running the following commands. Before proceed turn off your T4 and connect an SSD to your T4. Power on your T4 and open a command line utility(go to top left of the GUI and enter System Tools -> LXTerminal) or SSH to your T4.
We suggest you switch to "root" by running the following command:
su -The password for "root" is "fa".
7.7.1 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 by T4.
7.7.2 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.
7.7.3 将分区格式化为 ext4 格式
上一个步骤分区完成后，我们再用 cat /proc/partitions 命令看一下当前的分区信息，由于原厂内核会把PCIe nvme设备采取按eMMC相同的分区处理方式，所以你会看到SSD多出了一些额外的小分区。
我们需要看 blocks 这一列，找到容量最大的那个分区就是我们可用的分区了，在下面的结果中，可用于存储数据的分区设备名为 /dev/nvme0n1p7 :
root@FriendlyELEC:~# cat /proc/partitions major minor #blocks name 1 0 4096 ram0 259 0 125034840 nvme0n1 259 1 4096 nvme0n1p1 259 2 4096 nvme0n1p2 259 3 4096 nvme0n1p3 259 4 12288 nvme0n1p4 259 5 32768 nvme0n1p5 259 6 32768 nvme0n1p6 259 7 124932440 nvme0n1p7
下面的命令将该分区格式化为 ext4 格式：
mkfs.ext4 /dev/nvme0n1p7
7.7.4 让Lubuntu能在开机时自动挂载 SSD 分区
首先，我们需要了解分区的Block ID，用blkid查看:
blkid /dev/nvme0n1p7 /dev/nvme0n1p7: UUID="13fb682e-ef40-4c71-b98b-3d17403e1205" TYPE=“ext4"
然后需要把 Block ID 添加到 /etc/fstab 文件中去，格式为
UUID=<Block ID> /media/nvme ext4 defaults 0 0
其中，<Block ID>请替换成 blkid 得到的UUID结果，为了挂载本例中使用的SSD，/etc/fstab内容如下所示：
UUID=13fb682e-ef40-4c71-b98b-3d17403e1205 /media/nvme ext4 defaults 0 0
我们会将SSD挂载到 /media/nvme目录，这个目录默认是不存在的，我们用以下命令手动创建它，并设置为普通用户可以读写：
mkdir /media/nvme chmod 777 /media/nvme
接下来就可以输入mount命令，测试一下是否能正常挂载了：
mount /media/nvme
接下来我们关机测试一下，看下次开机是否会自动挂载：
poweroff
关机后重新开机，进入Lubuntu，应该能在桌面上看到已经挂载的SSD分区了，如下图所示：
7.7.5 SSD Read & Write
You can test SSD read and write speed. In our test we used an Intel SSD 600P 128GB hard disk. Different SSDs may have different results.
Write to SSD:
# dd if=/dev/zero of=/media/nvme/deleteme.dat bs=32M count=128 128+0 records in 128+0 records out 4294967296 bytes (4.3 GB, 4.0 GiB) copied, 21.3773 s, 201 MB/s
Read from SSD:
# dd if=/media/nvme/deleteme.dat of=/dev/zero bs=32M count=128 128+0 records in 128+0 records out 4294967296 bytes (4.3 GB, 4.0 GiB) copied, 13.623 s, 315 MB/s
8 Make Your Own OS Image
8.1 Setup Development Environment
If you want to compile an Android image we suggest you use a PC running a 64-bit Ubuntu 16.04.
sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip sudo apt-get install flex curl libncurses5-dev libssl-dev zlib1g-dev gawk minicom sudo apt-get install openjdk-8-jdk

8.2 Install Cross Compiler
8.2.1 Install aarch64-linux-gcc 6.4
Download and extract compiler:
git clone https://github.com/friendlyarm/prebuilts.git sudo mkdir -p /opt/FriendlyARM/toolchain sudo tar xf prebuilts/gcc-x64/aarch64-cortexa53-linux-gnu-6.4.tar.xz -C /opt/FriendlyARM/toolchain/
Add the compiler's path to the PATH variable by appending the following lines to the " ~/.bashrc " file:
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin:$PATH export GCC_COLORS=auto
Run the " ~/.bashrc " script. Note there is a space after the first ".":
. ~/.bashrcThis a 64-bit compiler. It cannot be run on a 32-bit OS. After it is installed you can check if it is correctly installed by running the following commands:
