NanoPC-T3 Octa-core Cortex A53 Single Board Computer


FriendlyARM launched NanoPC-T2 single board computer based on Samsung 5P4418 quad core Cortex A9 processor about 3 months ago, and the company has now an update based on Samsung S5P6818 Octa-Core A53 processor with the exact same interfaces and features including Gigabit Ethernet, WiFI, and Bluetooth, HDMI 1.4a, 30-pin expansion headers, etc…

NanoPC-T3 specifications:
SoC – Samsung S5P6818 octa core Cortex A53 processor @ up to 1.4GHz with Mali-400MP GPU
System Memory – 1 or 2GB 32bit DDR3 RAM
Storage – 8GB eMMC flash, and 1x SD card slot
Connectivity – Gigabit Ethernet (RTL8211E), 802.11 b/g/n WiFi and Bluetooth LE 4.0 (Ampak AP6212) with on-board chip antenna and IPX antenna connector
Video Output / Display I/F- 1x HDMI 1.4a, LVDS, MIPI DSI, parallel RGB LCD
Audio I/O – HDMI, 3.5mm audio jack, on-board microphone
Camera – 1x DVP interface, 1x MIPI CSI interface
USB – 2x USB 2.0 type A host ports; 1x micro USB 2.0 OTG port; 2x USB 2.0 host ports via 8-pin header
Expansions Headers – 30-pin header for GPIO, 8-pin header for power signals, reset and LED 1-2
Debugging – 4-pin header for serial console
Misc – Power switch, reset button, 1x power & 2x user LEDs, RTC battery header, boot selection button (SD card / eMMC)
Power Supply – 5V/2A via power barrel; AXP228 PMIC
Dimension – 100 x 60 mm (6-layer PCB)
64-bit_octa-core_ARM-development-boardThe board can run Android and Debian from eMMC flash or SD card like its predecessor, as well as Ubuntu Core with Qt, and software and hardware documentation can be found on the Wiki. The board ships with the heatsink shown in the top picture.
The board can be bought on FriendlyARM website for $60 + shipping via China Post ($10), Fedex ($14) or DHL ($34). Shipping fees in brackets are for my location, so you may get other quotes.

Question LVDS interface

Now I received their NanoPC-T3,but i want to use lvds interface to use my LCD,but i donot know how to use it ,i asked them via email how to support lvds interface,they replied me as ,i have to compile the kernel to support the lvds.
1. First i have to config the kernel configuration menu like this:
make menuconfig
Device Drivers --->
Graphics support --->
Nexell Graphics --->[*] LVDS
(0) Display In [0=Display 0, 1=Display 1]
and then i can use lvds interface,but i have to change uboot to detect LCD,but i donot have any idea about that ,anyone could give me some advice ?

Hi jiatang,

I have the same problem with the LVDS interface. I changed the kernel configuration with LVDS enabled but my display is still not working.
I think I have to change the bootargs "lcd=HDMI720P60" with something like "lcd=lvds" and create my own lvds config in the kernel configuration linux-3.4.y/arch/arm/plat-s5p6818/nanopi3/lcds.c but I am not sure.
Did you solve it ? Or do you have any idea how to do that ?

Thanks,

I got some information from friendlyelec,maybe you can refer:

'If you want to use LVDS display,you need clone our kernel source coed to compile.
a. First you should change kernel configuration to open lvds interface:
make menuconfig
Device Drivers --->
Graphics support --->
Nexell Graphics --->[*] LVDS
(0) Display In [0=Display 0, 1=Display 1]
b. After doing above steps,if the board doesn't detect lvds display,you can modify uboot source code,such as you can check/proc/cmdline file which includes lcd=HDMIxxx .
c. There should be display something after opening kernel configuration of LVDS,but you need to modify arch/arm/plat-s5p6818/nanopi3/lcds.c to add LCD timing configuration .
d. Actually we didn't test lvds display under uboot.
e. If the board cannot detect display's type,you need do these steps:
1. You need to modify uboot to make it notice kernel correct LCD type;

2. Or you can modify kernel source code lcds.c,forced LCD models,that is to say you
'

Hi jiatang,
I got the same informations from friendlyarm but I don't know how I can modify the file lcds.c to get my lvds working...

I did the first step:
make menuconfig
Device Drivers --->
Graphics support --->
Nexell Graphics --->[*] LVDS
(0) Display In [0=Display 0, 1=Display 1]
and I detect my lvds display but it's not working well, colours are not good, touchscreen and backlight are not working.
