Introduction

The Nano PC board is a Cortex-A9 embedded processing board that uses the Samsung Exynos4412 Quad-Core System On Chip (SOC).

The Exynos4412 integrates the Mali-400 MP GPU graphic engine with hardware support for 3D and can drive video playing on screens up to 1080P. These features make it easily and widely used in MID development, Android notepads, auto electronic devices, industrial applications, GPS systems and multimedia systems.

Nano PC Board

The Nano PC standard version integrates 1G DDR3 RAM and 4G eMMC flash memory.

Get Started

We provide various OS image files. Users can flash those files to the board via an SD card. We will guide you through these steps in this chapter.

Burning Superboot to SD Card

In order to boot from an SD card, you need to burn BIOS to it. FriendlyARM offers a flashing utility: SD-Flasher.exe which can burn our Bootloader (Superboot4412.bin) to an SD card.

We tested the following steps on Windows7.

   Note: users complained that some notebook’s integrated SD card reader cannot work properly with card burning or reading. So far we haven’t encountered this issue and we suggest that you should try a common card reader in this case.
   Our SD-Flasher.exe formats a 130M space for the bootloader therefore an SD card whose memory is less than 256M cannot work and we recommend using one whose memory is at least 4G.

Step1: launch the SD-Flasher.exe in your shipped CD (under “\tools\”). Note: this program should be run as “administrator”.

When the utility is launched a message box will pop up “Select your Machine”, please select “Mini4412/Tiny4412”:

Below is the dialog you will see after it is started. Note: the “ReLayout” is enabled and we will format the SD card with this function.

Step2: click onto select your bootloader file

Step3: insert a FAT32 SD card into your host’s SD card socket (you can also use a USB card reader to connect to a PC), backup your data in the card and click on “Scan”, all recognized SD cards will be listed.

Step4: click on “ReLayout”, the following dialog will pop up prompting you that the data in your card will be lost. Just click on “Yes”

After formatting is done you will be directed back to the main menu. Click on “Scan”, you will see that a “FriendlyARM” section available.

Step5: click on “Fuse”, Superboot will be safely burned into the SD card. You can burn this card in WindowsXP without worrying about its FAT32 data being lost or damaged.

Run Ubuntu on Nano PC from SD Card

We have a Ubuntu image for the NanoPC. Here are the steps to flash the image files to the Nano.

Prepare SD Card

Step 1: download the image file “ubuntu_nanopc_t1_sd_8g.img”

Step 2: get an SD card whose minimum memory is 8G.

Step 3: flash the image file to the SD card in Windows or Linux.

 On windows we use a free utility win32diskimager to copy the ubuntu image to the SD card.

 On Linux we use “dd” command to write the ubuntu image file to the SD card. For user’s convenience we have a shell “hc_fuse_ubuntu.sh” which can do so too.

1. !/bin/bash

DEV_NAME=$1

IMG=$2

BLOCK_CNT=`cat /sys/block/${DEV_NAME}/size`

if [ ${BLOCK_CNT} -le 0 ]; then

    echo "Error: NO media found in card reader."
  
    exit 1

fi

if [ ${BLOCK_CNT} -gt 32000000 ]; then

    echo "Error: Block device size (${BLOCK_CNT}) is too large"

    exit 1

fi

set -x

umount ${DEV_NAME}1 2>/dev/null

umount ${DEV_NAME}2 2>/dev/null

umount ${DEV_NAME}3 2>/dev/null

umount ${DEV_NAME}4 2>/dev/null

dd if=${IMG} of=${DEV_NAME} bs=1M

sync

We assume the SD card’s device node is “/dev/sdb” under ubuntu and the “ubuntu_nanopc_t1_sd_8g.img” file under this directory. Please run the command below:

1. sudo ./hc_fuse_ubuntu.sh /dev/sdb ./ubuntu_nanopc_t1_sd_8g.img

Run Ubuntu from SD

After you make an SD card by following the above steps you can run it on the NanoPC

Step 1: connect the Nano to a TV via an HDMI cable

Step 2: connect a USB mouse and keyboard

Step 3: switch S2 to “SD” and power on. If everything is set correctly you will see the following screenshot

Set HDMI Resolution

  Users can set the HDMI’s resolution in Uboot’s commandline. The default is as follows:

root=/dev/mmcblk0p2 rootfstype=ext4 console=ttySAC0,115200n8 lcd=S70 skipcali=y ctp=2 video=HDMI-A-1:1920x1080@60

  Users can change the “video” parameter to set the resolution. For example to set it to 1280 x 720 you can set it to:

root=/dev/mmcblk0p2 rootfstype=ext4 console=ttySAC0,115200n8 lcd=S70 skipcali=y

ctp=2 video=HDMI-A-1:1280x720M@60

  Here are the steps to change the resolution:

Step 1: connect the NanoPC to a PC via a TTL2RS232 board

Step 2: power on the board from “SD” and as soon as the board is powered on press any key to enter the bootloader’s commandline mode

Step 3: run the command below to change the parameter

1. set bootargs root=/dev/mmcblk0p2 rootfstype=ext4 console=ttySAC0,115200n8 lcd=S70 skipcali=y ctp=2 video=HDMI-A-1:1280x720M@60

Step 4: run “ saveenv” to save the change

Flash Ubuntu to Nano PC

We have a Ubuntu image for the NanoPC. Here are the steps to flash the needed files to the Nano PC. The minimum requirement for the eMMC is 8G.

Step 1: please follow the steps in the previous section to run Ubuntu from an SD card

Step 2: enter the root directory of the ubuntu system and you will find a “UBUNTU_INSTALL” directory. Enter this directory

Step 3: you will find these files “superboot4412.bin”, “zImage”, “rootfs.tar.gz”, “INSTALL” and “eflasher”

Step 4: please run “sudo ./INSTALL”. The password is “123456”.

The installation takes about 10 minutes. After it is done restart the Nano from “NAND” you will see ubuntu loading.

Set HDMI Resolution

When run Ubuntu from eMMC you can change the HDMI resolution by following the steps below

Step 1: install MiniTools

File:NanoPC16.jpg

Step 2: select “Linux” and check “Kernel commandline”

Step 3: click on “Start Flashing”. After it is done restart the Nano you can verify your change.
