Download and Build

Prebuilt Image

Download from FTP
Download from Baidu Netdisk

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

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):

SDK Source Code Downloading

Download from Github
Download from Baidu Netdisk

Building

Setup env

• For Lindenis-V853 AI EVB DevKit:

$ 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. v853_lindenis-tina

Which would you like? [Default v853_lindenis]: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

$ add-prebuilts-to-rootfs --ext4
$ pack

Installation

PhoenixSuit

• 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.

• You can trigger the image downloading follow these step:
  • 1) Connect the EVB to your PC via a USB cable, and you will see the green light. If you get a blue one, click the USB Select button to switch it.
  • 2) Keep long press the "FEL" key, then press the "RESET" key to reset the board. Please just keep pressing the "FEL" key.

• Release the "FEL" key when you see below PC pop-up.

• 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.

Tina Linux OS

Overview

Tina Linux is an embedded OS developed by Allwinner based on openwrt-14.07 SDK. The OS architecture of Tina Linux is shown in the following diagram, from bottom to top, which are Kernel & Driver, Libraries, System Services and Applications.

Tina Linux Architecture

Applications

Applications layer is mainly to implement specific product functions and interaction logic. Developers can flexibly develop their own applications to achieve the various needs of customers.

System Services

System Services layer provides system infrastructure services, including system boot management, configuration management, storage and memory management, multimedia middleware, etc.

Libraries

Libraries layer contains support for various system base libraries and third-party open source libraries, which allows system developers and application developers to develop new system services and applications based on the APIs provided by this layer.

Kernel & Driver

Kernel & Driver layer is the standard implementation of the Linux Kernel. And the Tina SDK for V853 is based on Linux-4.9 kernel.
