Download and Build
Prebuilt Image
For fast begin, you can download the [prebuilt image here.
国内开发者请在此下载提取码:4p3h
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):
tom ALL=(ALL) NOPASSWD: ALL
Ctrl-X to leave, save your changes, and you're done!
Downloading
The SDK is available on github. For Chinese developer, it is available on gitee too.
由于国内从Github上下载速度较慢,建议从Gitee上下载 --> Another way to get the SDK from Gitee
We use Repo manage Git repositories. Clone Repo from android Git repositories or other mirrors and install it.
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:
$ mkdir lindenis-v536 $ cd lindenis-v536 $ repo init -u https://github.com/lindenis-org/manifest.git -b v536 -m lindenis-v536.xml $ repo sync
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
Building
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 --For eMMC 2. v536_Lindenis_SOM-tina --For SPINOR 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
Installation
- Install the eMMC module on the board.
- Download the PhoenixSuit_V1.1.0.7z (Click here)and extract to a local folder (note: Windows only) and run one of the installers.
- Open the PhoenixSuit.exe.
- Click the "firmware" button.
- Click the "image" button to select the image file.
- For Lindenis_V536_DIBAN_V2_0, Make sure the two USB shift switches Switch A and Switch B on the right gear like the picture. Switch A should be on "ON" and Switch B should be on "1".
- For Lindenis_V536_DIBAN_V3_0, it's a new way. You just only need to press down the key.Like the picture show you.
- 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
Uart
- 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.
Camera
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.
- If you cannot access the files, please send an e-mail to services@lindeni.com .
Display
- 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):
LCD:
fdt set disp screen0_output_type <0x01>; fdt set disp screen0_output_mode <0x04>; fdt save; reset;
HDMI (1080p):
fdt set disp screen0_output_type <0x03>; fdt set disp screen0_output_mode <0x0a>; fdt save; reset;
- 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) ;---------------------------------------------------------------------------------- [disp] disp_init_enable = 1 disp_mode = 0 screen0_output_type = 3 screen0_output_mode = 10
