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.
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.

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
