Remote access


Follow the instructions on


sudo apt-get install x11vnc

The following file shoud be opened ~/.config/lxsession/LXDE/autostart and this line should be added to the bottom:

@x11vnc -noxrecord -forever

noxrecord fixes a problem it has with stack smashing on this board

forever option keeps the server alive after a connect and disconnect from a client

It must be restarted to run without a terminal.

If you do not have a USB keyboard it is possible to install virtual keyboard via ssh with command ‘sudo apt-get install matchbox-keyboard’. To run the virtual keyboard run the ‘matchbox-keyboard’ in the terminal.

How to build Kernel/U-boot source code


Get source code:

$ git clone -b release

Building image:

$ cd debian_u-boot
            $ make CROSS_COMPILE=arm-linux-gnueabihf- O=miniarm-rk3288 tinker-rk3288_defconfig all -j4 
            $ miniarm-rk3288/tools/mkimage -n rk3288 -T rksd -d miniarm-rk3288/spl/u-boot-spl-dtb.bin u-boot.img
            $ cat miniarm-rk3288/u-boot.bin >> u-boot.img

Flash image:

Prepare one sdcard which has the full Debian image inside.

Then insert the sdcard into a linux based OS, and suppose the block device of the sdcard is /dev/sdx

 $ sudo dd if=[path]/u-boot.img of=/dev/sdx seek=64


Install the related packages:

$ sudo apt-get install git-core gitk git-gui gcc-arm-linux-gnueabihf gcc-arm-linux-gnueabi device-tree-compiler gcc-aarch64-linux-gnu mtools parted libssl-dev fakeroot

Get source code:

$ git clone -b release

Building image:

$ cd debian_kernel
            $ make miniarm-rk3288_defconfig ARCH=arm -j16
            $ make zImage ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
            $ make modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
(Note: As of 2018-01-05, if may be necessary to edit the Makefile to add -Wno-misleading-indentation to the CFLAGS_MODULE 
$ make modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 CFLAGS_MODULE=-Wno-misleading-indentation
            $ make rk3288-miniarm.dtb ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
            $ make dtbs ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16

Flash image:

Prepare one sdcard which has the full Debian image inside.

  1. Install WIFI module to root file system:
  1.1 Insert sd card to linux pc and then mount partition 2 (rootfs partition) suppose the block device of the sdcard is /dev/sdx
$ sudo mkdir –p /media/users/sdx2
            $ sudo mount /dev/sdx2 /media/users/sdx2
1.2 Open terminal to kernel folder and enter the following commands
$ sudo make ARCH=arm INSTALL_MOD_PATH=/media/users/sdx2 modules_install
            $ sudo umount /media/users/sdx2
2. Replace the kernel image:
            2.1 Insert sd card to linux pc and then mount partition 1 (boot partition)
                suppose the block device of the sdcard is /dev/sdx
$ sudo mkdir –p /media/users/sdx1
            $ sudo mount /dev/sdx1 /media/users/sdx1
2.2 Open terminal to kernel folder and copy zImage and rk3288-miniarm.dtb to partition 1
$ cp arch/arm/boot/zImage /media/users/sdx1
            $ cp arch/arm/boot/dts/rk3288-miniarm.dtb /media/users/sdx1
            $ sudo umount /media/users/sdx1
NOTE: The step 1.1 and 2.1 should be skipped since most of the linux distribution will mount the sdcard automatically.

PXE boot

Image version

Please use the image version before V1.9.1 (include), or after V2.0.5 (include).

NOTE : There is some problem from the image version V2.0.1 to V2.0.4, we have fixed it at V2.0.5.

Install tftp

1. Install following packages

sudo apt install xinetd tftpd

2. Create /etc/xinet.d/tftp and put this entry

service tftp
              protocol     = udp
              port         = 69
              socket_type  = dgram
              wait         = yes
              user         = nobody
              server       = /usr/sbin/in.tftpd
              server_args  = -s /tftpboot
              disable      = no

3. Create a folder /tftpboot

sudo mkdir /tftpboot
            sudo chmod -R 777 /tftpboot
            sudo chown -R nobody /tftpboot

4. Restart the xinetd service.

sudo service xinetd restart

Install nfs

1. Install following packages

sudo apt install nfs-kernel-server nfs-common

2. Create a folder/var/nfsshare

                  sudo mkdir /var/nfsshare
sudo chmod -R 777 /var/nfsshare

3. Create /etc/exports and put this entry


4. Restart NFS server

/etc/init.d/nfs-kernel-server restart

PXE Boot

1.Set up a DHCP server as a PXE server. This server must provide functions of TFTP server and NFS server.

2.Prepare PXE config file in tftpboot directory. Create a directory “pxelinux.cfg” in tftpboot directory. The file name of PXE config is “default ”. The patch of PXE config should be :

“/tftpboot/pxelinux.cfg/default ” The content of PXE config is like “/boot/extlinux/extlinux.conf ” in Tinker Board, but the path of rootfs should be modified. The following is an example. “ ” is IP of NFS server. “/nfs/rootfs/ ” is path of NFS ROOT.

label kernel-4.4
              kernel /zImage
              fdt /rk3288-miniarm.dtb
              append  earlyprintk console=tty1 console=ttyS1,115200n8 root=/dev/nfs nfsroot= rw ip=dhcp rootwait elevator=deadline

1.Put the following files into tftpboot directory for PXE boot. hw_intf.conf: You can get it from “/boot/hw_intf.conf ” in Tinker Board. rk3288-miniarm.dtb: Device Tree config for Linux kernel. zImage: Linux kernel image with NFS functions(CONFIG_IP_PNP, CONFIG_IP_PNP_DHCP, CONFIG_IP_PNP_BOOTP, CONFIG_IP_PNP_RARP, and CONFIG_ROOT_NFS). The paths should be : “/tftpboot/hw_intf.conf “, “/tftpboot/rk3288-miniarm.dtb”, “/tftpboot/zImage”

2.Copy the whole rootfs of Tinker Board into NFS directory in NFS server. According to the example above, the path of NFS ROOT in NFS server should be: “/nfs/rootfs” This path needs to be shared by NFS server. Modify the partition definitions in “/nfs/rootfs/etc/fstab”. There should be only one partition.

proc            /proc           proc    defaults          0       0

3.Remove the following files in Tinker Board. “/boot/rk3288-miniarm.dtb” “/boot/zImage” The bootloader will start PXE boot if these files are removed from Tinker Board.

HDMI resolution

How to change the HDMI resolutions

Method 1 : from UI intereface

Using the Monitor settings to change the resolution directly.

Method 2 : Terminal (Command line) – Xrandr

The following is the wiki of the xrandr

# list all the available output resolution
            $ xrandr

then you can use xrandr to set different resolution (must be present in the above list) on some output:

$ xrandr --output HDMI-1 --mode 1920x1080

Adding for unlisted resolution

$ cvt 1024 768 60
            # 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz
            Modeline "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
            $ xrandr --newmode "1024x768" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
            $ xrandr --addmode HDMI1 1024x768
            $ xrandr --output HDMI1 --mode 1024x768

Method 3 : Editing /etc/X11/xorg.conf.d/20-modesetting.conf (Need to reboot)

Section "Device"
                Identifier  "Rockchip Graphics"
                Driver      "modesetting"
                Option      "AccelMethod"    "glamor"
                Option      "DRI"            "2"
            Section "Monitor"
                Identifier "Monitor 0"
                Modeline "1024x768_60.00" 63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync
            Section "Screen"
                Identifier "Default Screen"
                Monitor "Monitor 0"
                SubSection "Display"
                    Depth 24
                    Modes "1024x768_60.00"

Method 4 : Add a file to the folder of /boot/hdmi (Need to plug in-out)

Add a new file of hdmi_set_resolution.cfg, and write the resolution which you want in the file.

Then put it in this folder “/boot/hdmi” or the hdmi folder which is in your sdcard. (These 2 paths are the same)

There is a example in the attached file.

Static boot logo


1.Please prepare the 24 bit bmp file and the length/width must be divisible by 4.
For example: 1000×400, 1920×1080 are OK, but 1921×1000 is not allowed
We recommended that you can use the Microsoft paint to save the picture as the 24 bit bmp.
Let's assume the picture name is logo.bmp

2.Use the linux tool "convert" to change the format

$ convert -compress rle -colors 256 logo.bmp logo_kernel.bmp

logo.bmp is the file which is came from step 1 and logo_kernel.bmp is the file which is after convert.

Android M:
3.Replace the logo.bmp and logo_kernel.bmp which is came from step 1 and step 2 to the kernel folder
Android N:
3.use the logo_kernel.bmp which is came from step 2 to replace the logo.bmp and logo_kernel.bmp at kernel folder

4.Rebuild kernel image

How to rebuild kernel:

NOTE: Please notice that the version of "convert" is also importance. The version of convert must be equal to the below

$ convert -version

Please check the following 2 commits. One is for HDMI and the other is for DSI.

How to Rotate screen

Tinker Board can support rotate screen 0/90/180/270 degree. Please reference for the below 2 POSTs.

set the ro.sf.hwrotation in build.prop file

$ adb connect [ip address of tinkerboard]
            $ adb root
            $ adb connect [ip address of tinkerboard]
            $ adb remount
            $ adb pull /system/build.prop .

Then, edit the pulled build.prop file with a text editor. You want to focus on this particular property:

This properties has 4 options

# other possible values: 
            # 0 = Landscape, 90 = Portrait, 180 = reverse Landscape, 270 = Reverse Portrait

Please note that the 180 degree needs to use the image after 20180613.
After editing, push the build.prop back to the device

$ adb push build.prop /system/build.prop

Set the persist.demo.hdmirotation property

# for 0/180 degree
            $ adb shell "setprop persist.demo.hdmirotation landscape"
            # for 90/270 degree
            $ adb shell "setprop persist.demo.hdmirotation portrait"

finally reboot the device.

How to connect DSI and CSI cable

  • DSI, CSI cable can be use will no difference, those cable is the same.
  • CSI connect to the middle of tinker board, please refer icon print on board as follows:
  • DSI connect to the boundary of tinker board, please refer icon print on board as follows:
  • DSI panel need extra 5V power. You can USB to supply, or thinker board can output 5V by GPIO PIN, red line is for positive(+),black line is for negative(-) , as follow.
  • You need to notice the direction, when you install cable, the principle is: blue side is face outside of the tinker board.



How to trigger CSI

  • Use Build-in Camera test tool for operation.
  • Some operations need root permission to execute.
  • Run "sudo su" in terminal command line before operation.

Camera Preview:


camHalTest.bin  0


camHalTest.bin  1

0 for show preview in DSI

1 for show preview in HDMI

Camera preview will be showed on specific display equipment.


Each time executing Capture needs to run below cmd to setup environment.

sh  /home/linaro/camera/

Then key-in capture cmd:


Five pictures will be taken and placed in /tmp/isptune with ppm filename extension.

Build-in file viewer is capable to open and view the image.


  1. All contents in /tmp/ are volatile and will disappear after reboot.
  2. Disk space for /tmp/ is only ~300MB and one ppm image size is ~22MB, so it can only save ~12 pictures. Make sure to move (mv) image files to external storage before next Capture operation of stress test.

Camera SOP/Camera Config


Warning: Cameras are sensitive to static. Earth yourself prior to handling the PCB. A sink tap or similar should suffice if you don't have an earthing strap.

The camera board attaches to the Tinker Board via a 15-way ribbon cable. There are only two connections to make: the ribbon cable needs to be attached to the camera PCB, and to the Tinker Board itself. You need to get the cable the right way round, or the camera will not work. On the camera PCB, the blue backing on the cable should face away from the PCB, and on the Tinker Board it should face towards the Ethernet connection (or where the Ethernet connector would be if you're using a model A).

Although the connectors on the PCB and the Tinker Board are different, they work in a similar way. On the Tinker Board itself, pull up the tabs on each end of the connector. It should slide up easily, and be able to pivot around slightly. Fully insert the ribbon cable into the slot, ensuring it is set straight, then gently press down the tabs to clip it into place. The camera PCB connector also requires you to pull the tabs away from the board, gently insert the cable, then push the tabs back. The PCB connector can be a little more awkward than the one on the Tinker Board itself.


Camera software is default built inside the release image. You don't need to do extra setup.

To test whether the Camera is working, try the following Gstreamer command:

$ gst-launch-1.0 v4l2src ! video/x-raw,format=NV12,width=640,height=480 ! videoconvert ! autovideosink

The display should show a preview from the Camera, whilst displaying various informational messages.


If the Camera Module isn't working correctly, please use below command to check whether the Camera Module be detected by Tinker Board.

$ ls /dev/video*

You will see /dev/video0 /dev/video1 /dev/video2. If not, there are number of things to try:

  1. Is the ribbon cable attached to the Camera Serial Interface (CSI), not the Display Serial Interface (DSI)? The ribbon connector will fit into either port. The Camera port is located near the HDMI connector.
  2. Are the ribbon connectors all firmly seated, and are they the right way round? They must be straight in their sockets.
  3. Is the Camera Module connector, between the smaller black Camera Module itself and the PCB, firmly attached? Sometimes this connection can come loose during transit or when putting the Camera Module in a case. Using a fingernail, flip up the connector on the PCB, then reconnect it with gentle pressure. It engages with a very slight click. Don't force it; if it doesn't engage, it's probably slightly misaligned.
  4. Is your power supply sufficient? The Camera Module adds about 200- 250mA to the power requirements of your Tinker Board.


The CSI Camera of Tinker Board support IMX219 and OV5647. Here describes the basic usage of Gstreamer and MJPEG-streamer.
