Download and Build

Prebuilt Image

For fast begin, you can download the [prebuilt image here.

System requirements

Listed below are the recommended requirements for downloading and building the SDK:

  • CPU: x86_64 or better family processor
  • Memory: 8GB or higher
  • Disk: 20GB free hard disk space, if you build it in a Virtual machine, I recommand you allocate a 30G virtual hard disk.
    • The Whole SDK is about 15G.
  • OS: Ubuntu 14.04 (tested) or higher
  • Network: internet connection

Lazy Start

Here are VMware station 14 image files which include the whole compiled SDK. And the SDK remote repositoreies are on gitee (not github).
Click here to get it (access code: tq4x)
The password of the Ubuntu 14.04 in the VMware is "lindenis". Enjoy it !

Linux host setup

Ubuntu 14.04

HINT: later version should also work.

Install prerequisites

$ sudo apt-get update
$ sudo apt-get install build-essential libncurses5-dev zlib1g-dev gawk git git-core ccache gettext libssl-dev xsltproc gperf subversion 
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install lib32z1 lib32ncurses5 libc6:i386 libstdc++6:i386

Sudo without password

$ sudo visudo

Add this line at the end (change “tom” to your username):


Ctrl-X to leave, save your changes, and you're done!


The SDK is available on github. For Chinese developer, it is available on gitee too.

We use Repo manage Git repositories. Clone Repo from android Git repositories or other mirrors and install it.
Chinese developers can install Repo follow these steps:

$ git clone http://mirrors.ustc.edu.cn/aosp/git-repo.git ~/.bin/repo
$ echo "export PATH=~/.bin/repo:$PATH" >> ~/.bashrc
$ source ~/.bashrc

Becase there are some big files in the SDK, please run the following command before you start the downloading.

$ git config --global http.postBuffer 524288000

Then run this to check:

$ git config --list

For Lindenis V536 SBC, download the SDK on Github via:(此为github的下载方式,国内下载较慢,请使用国内源的方式下载,见下文)

$ mkdir lindenis-v536
$ cd lindenis-v536
$ repo init -u https://github.com/lindenis-org/manifest.git -b v536 -m lindenis-v536.xml
$ repo sync

We recommend the Chinese developer download the SDK source code on gitee via:

$ mkdir lindenis-v536
$ cd lindenis-v536
$ repo init -u https://gitee.com/lindenis/manifest.git -b master -m lindenis-v536.xml
$ repo sync

And then download these two files from Baidu NetDisk, and then copy them into the target directory follow below steps:
dl.tar.gz (提取码: 575x)

$ cp dl.tar.gz lindenis-v536
$ tar xzvf dl.tar.gz dl/

libs.tar.xz (提取码: ljvj)

$ cp libs.tar.xz lindenis-v536/package/cortana/cortana-sdk

The Download time depends on your network connection speed. After finish the download, you should get below directories and files:

build  config  Config.in  device  dl  lichee  Makefile  package  prebuilt  rules.mk  scripts  softwinner  target  toolchain  tools

Start a branch for local workspace:

$ repo start lindenis-v536 --all


Setup env
  • For Lindenis V536 SBC:
$ source build/envsetup.sh
$ lunch

Then you will see the follwing menu, and enter the number to select the target case, and enter:

You're building on Linux

Lunch menu... pick a combo:
     1. v536_Lindenis_SBC-tina

Which would you like? [Default v536_Lindenis_SBC]:1
Build source
  • Build kernel and rootfs

If you are the first time downloaded the SDK and have not built the SDK before, run the below two commands, then exit and save the configuration at first.

$ make menuconfig
$ make kernel_menuconfig

Then make it and wait ...

$ make -j8 V=s
Build image
$ pack



  • Download the PhoenixSuit.7z and extract to a local folder (note: Windows only).
  • Open the PhoenixSuit.exe.


  • Click the "firmware" button.


  • Click the "image" button to select the image file.


  • Now the PC tool is ready. Just keep pressing the "fel" key on the SBC.


  • After connected the SBC to PC via a USB cable, release the key, and the PhoenixSuit will enter the burn model.


  • If you want to keep the user data, please click "No". Click "Yes" will clean all datas in eMMC.Then will begin to download the image into eMMC.
  • If you can not start to download, just plug-out the USB cable and try again.


  • Wait until it finish downloading.

System Setup

  • By default, the ttyS3 is assigned to the Linux console. The UART transmit pin called "TX" and receive pin called "RX" are in the J12 pin group, whose label is DEBUG. And the bit rate is 115200 bps.See below red rectangle.



The camera supports the imx317 module as default. If you need to change to imx307, you can follow the steps below:

  • 1.modify device/config/chips/v536/configs/Lindenis_SBC/sys_config.fex

find this:

sensor0_mname = "imx317_mipi"

change to:

sensor0_mname = "imx307_mipi"
  • 2. make menuconfig selection
Allwinner --->
    eyesee-mpp --->
        -*-eyesee-mpp-middleware ............... eyesee-mpp-middleware for Tina Linux
            select sensor (use sensor imx307) --->
        () use sensor imx317
        (X) use sensor imx307
         () use sensor imx278
        () use sensor imx258
        () use sensor imx386
        () use sensor sc2232
  • 3. do "make" and then flash the firmware.
ISP Tuning

Allwinner V536 ISP Tuning Tool | 国内提取码:c0u8

  • Download the HawkviewTools-V3.0.2.7z and extract to a local folder (note: Windows only).
  • Download the awTuningApp, push it into the board through ADB or SSH and then run it.
  • Please refer to the documents in docs folder for usage.
  • Because of the limitation that there is one display engine module in V536, Lindenis-V536 SBC can not support dual-display.
  • The default display device of the SDK and the prebuilt image is HDMI(1080p).
  • If you have download the prebuilt image, and burn it into eMMC, you can switch the display device follow these steps:

Connect serial to control the board

  • Firstly, you should connect the SBC debug UART to computer via a serial-USB cable so that you can send commands to the board through a PC serial software like Putty.
  • After you connected successfully, you will see the log show on the PC serial software like this:


Enter U-boot command mode

  • Power on and press any keyboard key within 1s when you see the message below, then you can enter u-boot command mode.
  • Under this mode, you can modify the kernel devices tree by FDT tools in u-boot.


Change display device configuration with FDT tool

  • Input the follow command to switch display device between LCD and HDMI (1080p):


fdt set disp screen0_output_type <0x01>;
fdt set disp screen0_output_mode <0x04>;
fdt save;

HDMI (1080p):

fdt set disp screen0_output_type <0x03>;
fdt set disp screen0_output_mode <0x0a>;
fdt save;
  • You can also select different display device via configuration in sys_config.fex
;disp init configuration
;disp_mode             (0:screen0<screen0,fb0>)
;screenx_output_type   (0:none; 1:lcd; 2:tv; 3:hdmi;5:vdpo)
;screenx_output_mode   (used for hdmi output, 0:480i 1:576i 2:480p 3:576p 4:720p50)
;                      (5:720p60 6:1080i50 7:1080i60 8:1080p24 9:1080p50 10:1080p60)

Application Demo

The application demos powered by Lindenis.Click here to download the demos


lindlive is a high performance low latency live streaming library. lindlive integrate some useful function modules, such as audio/video capture, encoding and streaming protocol. So developers can easily implement a live streaming server based on lindenis board.

There are two samples app using lindlive, one is sample_mppsrc_2_livesink and the other is sample_mppsrc_2_ffsink. The sample source code is located in SDK.

!!! It is strongly recommended to use lindplayer with '-live' as the client of the lindlive. It will be lower latency.


   sample_mppsrc_2_livesink -i [ip] -p [port] -n [name]
       -i [ip] is the ip address of the server. If it is not set, the 'ip' default is local ethernet or wifi ip address.
       -p [port] is the port of the server. If it is not set, the 'port' default is rtsp port 8554.
       -n [name] is the name of live streaming. If it is not set, the 'name' default is 'live'.
       All of the arguments are optional.
   If sample_mppsrc_2_livesink is correctly running, the server url is 'rtsp://[ip]:[port]/[name]'
   Then it can be played in an player with the url 'rtsp://[ip]:[port]/[name]'.
   sample_mppsrc_2_ffsink -t [type] -u [url]
       -t [type]: the muxer type, can be 'mpegts/mp4/rtp/rtp_mpegts/rtsp/rtmp'
       -u [url] : sink to url, like: '/tmp/out.mp4' or 'rtp://'
   Example 1: sink as a live streaming.
       sample_mppsrc_2_ffsink -t rtp_mpegts -u rtp://
       sample_mppsrc_2_ffsink -t rtp -u rtp://
       Then it can be played in an player with the url 'rtsp://[ip]:[port]/[name]'.
   Example 2: save as a local file.
       sample_mppsrc_2_ffsink -t mp4 -u /tmp/out.mp4
       sample_mppsrc_2_ffsink -t mpegts -u /tmp/out.ts
