Notes in Hardware Design

EEPROM

  • The board has an EEPROM(model: 24AA025E48T-I/OT) with a unique MAC. This EEPROM is connected to I2C0 and its address is 0x51 therefore some EEPROM chips cannot be connected to I2C0 which will cause conflicts of addresses.
  • In our tests these EEPROM chips cannot be connected to I2C0: 24C04, 24C08 and 24C16. There chips which we tested can be connected to I2C0: 24C01, 24C02 and 24C256
  • For more details about EEPROM address issues refer to http://www.onsemi.com/pub_link/Collateral/CAT24C01-D.PDF

Make Installation Card under Linux Desktop

  • 1) Insert your SD card into a host computer running Ubuntu and check your SD card's device name
dmesg | tail

Search the messages output by "dmesg" for similar words like "sdc: sdc1 sdc2". If you can find them it means your SD card has been recognized as "/dev/sdc". Or you can check that by commanding "cat /proc/partitions"

  • 2) Downlaod Linux script

git clone https://github.com/friendlyarm/sd-fuse_s5p6818.git
cd sd-fuse_s5p6818

  • 3) Here is how to make a Lubuntu desktop SD card
sudo ./fusing.sh /dev/sdx lubuntu

(Note: you need to replace "/dev/sdx" with the device name in your system)
When you run the script for the first time it will prompt you to download an image you have to hit “Y” within 10 seconds otherwise you will miss the download

  • 4) Run this command to make a complete image file:
sudo ./mkimage.sh lubuntu

More content please refre: Assembling the SD card image yourself

Extend SD Card Section

  • When Debian/Ubuntu is loaded the SD card's section will be automatically extended.
  • When Android is loaded you need to run the following commands on your host PC to extend your SD card's section:
sudo umount /dev/sdx?
sudo parted /dev/sdx unit % resizepart 4 100 resizepart 7 100 unit MB print
sudo resize2fs -f /dev/sdx7

(Note: you need to replace "/dev/sdx" with the device name in your system)

LCD/HDMI Resolution

When the system boots our uboot will check whether it is connected to an LCD or to an HDMI monitor. If it recognizes an LCD it will configure its resolution. Our uboot defaults to the HDMI 720P configuration.
If you want to modify the LCD resolution you can modify file "arch/arm/plat-s5p6818/nanopi3/lcds.c" in the kernel and recompile it.
If your NanoPC-T3 is connected to an HDMI monitor and it runs Android it will automatically set the resolution to an appropriate HDMI mode by checking the "EDID". If your NanoPC-T3 is connected to an HDMI monitor and it runs Debian by default it will set the resolution to the HDMI 720P configuration. If you want to modify the HDMI resolution to 1080P modify your kernel's configuration as explained above.

Update SD Card's boot parameters From PC Host

Insert your SD card into a host PC running Linux, if you want to change your kernel command line parameters you can do it via the fw_setevn utility.
Check the current Command Line:

git clone https://github.com/friendlyarm/sd-fuse_s5p6818.git
cd sd-fuse_s5p6818/tools
./fw_printenv /dev/sdx | grep bootargs

For example, to disable android SELinux, You can change it this way:

./fw_setenv /dev/sdc bootargs XXX androidboot.selinux=permissive

The "XXX" stands for the original bootargs' value.

Work with FriendlyCore

Introduction

FriendlyCore is a light Linux system without X-windows, based on ubuntu core, It uses the Qt-Embedded's GUI and is popular in industrial and enterprise applications.

Besides the regular Ubuntu core's features our FriendlyCore has the following additional features:

  • it supports our LCDs with both capacitive touch and resistive touch(S700, X710, HD702, S430, HD101 and S70)
  • it supports WiFi
  • it supports Ethernet
  • it supports Bluetooth and has been installed with bluez utilities
  • it supports audio playing
  • it supports Qt5.9 EGLES and OpenGL ES1.1/2.0 (Only for S5P4418/S5P6818)

FriendlyCore's User Accounts

  • If your board is connected to an HDMI monitor you need to use a USB mouse and keyboard.
  • If you want to do kernel development you need to use a serial communication board, ie a PSU-ONECOM board, which will allow you to operate the board via a serial terminal.Here is a setup where we connect a board to a PC via the PSU-ONECOM and you can power on your board from either the PSU-ONECOM or its MicroUSB:

For example, NanoPi-M1:
PSU-ONECOM-M1.jpg
You can use a USB to Serial conversion board too.
Make sure you use a 5V/2A power to power your board from its MicroUSB port:
For example, NanoPi-M1:
USB2UART-NEO2.jpg

  • FriendlyCore User Accounts:

Non-root User:

   User Name: pi
   Password: pi

Root:

   User Name: root
   Password: fa

The system is automatically logged in as "pi". You can do "sudo npi-config" to disable auto login.

  • Update packages
$ sudo apt-get update

Configure System with npi-config

The npi-config is a commandline utility which can be used to initialize system configurations such as user password, system language, time zone, Hostname, SSH switch , Auto login and etc. Type the following command to run this utility.

$ sudo npi-config

Here is how npi-config's GUI looks like:
npi-config

Develop Qt Application

Please refer to: How to build Qt application

Setup Program to AutoRun

You can setup a program to autorun on system boot with npi-config:

sudo npi-config

Go to Boot Options -> Autologin -> Qt/Embedded, select Enable and reboot.

Extend TF Card's Section

When FriendlyCore is loaded the TF card's section will be automatically extended.You can check the section's size by running the following command:

$ df -h

WiFi

For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:

Index Model
1 RTL8188CUS/8188EU 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601

You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:

  • Check device list
sudo nmcli dev

Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.

  • Start WiFi
sudo nmcli r wifi on
  • Scan Surrounding WiFi Sources
sudo nmcli dev wifi
  • Connect to a WiFi Source
sudo nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0

The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.

For more details about NetworkManager refer to this link: Use NetworkManager to configure network settings

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:

$ sudo apt-get install linux-firmware

In general all WiFi drivers are located at the "/lib/firmware" directory.

Setup Wi-Fi AP

Follow the steps below. Since our OS image by default already has the NetworkManager utility you will be prompted to uninstall it first:

sudo turn-wifi-into-apmode yes

After you uninstall the NetworkManager reboot your board.
After your board is rebooted run the above commands again and you will be prompted to type in a WIFI's name and password. Type in your wanted name and password

If this is successful you will be able to find and connect your board to a WIFI. Login to your board at 192.168.8.1:

ssh root@192.168.8.1

Type in a password. In our system the password is "fa".

To login smoothly via SSH we recommend you turning off WIFI's power save mode by running the following commands:

sudo iwconfig wlan0 power off

You can check your WiFi's mode by running the following command:

sudo cat /sys/module/bcmdhd/parameters/op_mode

Number 2 means your WiFi is in AP mode. You can switch to the Station mode by running the following command:

sudo turn-wifi-into-apmode no

Bluetooth

If your board has an onboard bluetooth module you can search for surrounding bluetooth devices by running the following command:

hcitool scan

You can run "hciconfig" to check bluetooth's status.

Ethernet Connection

If a board is connected to a network via Ethernet before it is powered on it will automatically obtain an IP with DHCP activated after it is powered up. If you want to set up a static IP refer to: Use NetworkManager to configure network settings

Set Audio Device

If your system has multiple audio devices such as HDMI-Audio, 3.5mm audio jack and I2S-Codec you can set system's default audio device by running the following commands.

  • After your board is booted run the following commands to install alsa packages:
$ apt-get update
$ apt-get install libasound2
$ apt-get install alsa-base
$ apt-get install alsa-utils
  • After installation is done you can list all the audio devices by running the following command. Here is a similar list you may see after you run the command:
$ aplay -l
card 0: HDMI
card 1: 3.5mm codec
card 2: I2S codec

"card 0" is HDMI-Audio, "card 1" is 3.5mm audio jack and "card 2" is I2S-Codec. You can set default audio device to HDMI-Audio by changing the "/etc/asound.conf" file as follows:

pcm.!default {
    type hw
    card 0
    device 0
}
 
ctl.!default {
    type hw
    card 0
}

If you change "card 0" to "card 1" the 3.5mm audio jack will be set to the default device.
Copy a .wav file to your board and test it by running the following command:

$ aplay /root/Music/test.wav

You will hear sounds from system's default audio device.
If you are using H3/H5/H2+ series board with mainline kernel, the easier way is using npi-config

Run Qt5.9 Demo with GPU acceleration

Run the following command

$ sudo qt5demo

S5pxx18-QtE

Run Qt5.9 Demo with OpenGL

Run the following command

. setqt5env
cd $QTDIR
cd /examples/opengl/qopenglwidget
./qopenglwidget

For more Qt5.9 examples, please go to:
cd $QTDIR/examples/

Play HD Video with Hardware-decoding

gst-player is console player, it base on GStreamer, support VPU with Hardware-decoding:

sudo gst-player /home/pi/demo.mp4

The equivalent gsteamer command is as follows:

sudo gst-launch-1.0 filesrc location=/home/pi/demo.mp4 ! qtdemux name=demux demux. ! queue ! faad ! audioconvert ! audioresample ! alsasink device="hw:0,DEV=1" demux. ! queue ! h264parse ! nxvideodec ! nxvideosink dst-x=0 dst-y=93 dst-w=1280 dst-h=533

Connect to DVP Camera CAM500B

The CAM500B camera module is a 5M-pixel camera with DVP interface. For more tech details about it you can refer to Matrix - CAM500B.
Under Debian/Ubuntu a camera utility "nanocams" is available for previewing 40 frames and picture taking. You can try it by following the commands below

sudo nanocams -p 1 -n 40 -c 4 -o IMG001.jpg

For more details about the usage of the nanocams run "nanocams -h". You can get its source code from our git hub:

git clone https://github.com/friendlyarm/nexell_linux_platform.git

Power Off and Schedule Power On

“PMU Power Management” feature helps us to auto power on the board at a specific time, it is implemented by an MCU, support software power-off, and RTC alarm power-up functions.

Here’s a simple guide:
Turn on automatically after 100 seconds. (Time must be greater than 60 seconds.):

$ sudo echo 100 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

After setting up the automatic boot, turn off board with the 'poweroff’ command:

$ sudo poweroff

Cancel automatic boot:

$ sudo echo 0 > /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm

Query the current settings, in the front is current time, followed by the time of automatic booting: If no automatic boot is set, it will display "disabled”.

$ sudo cat /sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm


Note that some older versions of hardware may not support this feature, if you don't see this file node in your system:
/sys/class/i2c-dev/i2c-3/device/3-002d/wakealarm
your board may be it does not support this feature.

Compile Linux kernel 4.4.y

Compile Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux.git -b nanopi2-v4.4.y --depth 1
cd linux

The kernel source for S5P6818 is in the "nanopi2-v4.4.y" branch. Before you start compiling it you need to switch to this branch.

  • Compile Ubuntu Kernel
touch .scmversion
make ARCH=arm64 nanopi3_linux_defconfig
make ARCH=arm64

After your compilation succeeds an "arch/arm/boot/Image" will be generated and a DTB file(s5p6818-nanopi2-rev*.dtb) will be generated in the "arch/arm/boot/dts/nexell" directory. You can use them to replace the existing Image and DTB files in the boot partition of your bootable SD card.

Use Your Generated Kernel

  • Update kernel in SD card

If you use an SD card to boot Ubuntu you can copy your generated Image and DTB files to your SD card's boot partition(e.g. partition 1 /dev/sdX1).

  • Update kernel in eMMC

If you boot your board from eMMC you can update your kernel file by following the steps below:
1) Usually after OS is loaded eMMC's boot partition (in our example eMMC's device name was /dev/mmcblk0p1) will be automatically mounted and you can verify that by running "mount"
2) Connect your board to a host PC running Ubuntu and copy the Image and DTB files to eMMC's boot partition
3) Or you can copy your generated kernel file to an external storage card(e.g. an SD card or a USB drive), connect the storage card to your board the move the file from the card to eMMC's boot partition
4) After update is done type "reboot" to reboot your board. Note: don't just directly disconnect your board from its power source or press the reset button to reboot the board. These actions will damage your kernel file

  • Generate Your boot.img

If you want to generate an image file that can be flashed to eMMC you need to generate a boot.img file and then copy it to your installation SD card
For Ubuntu follow the steps below to generate a boot.img file:
1) Download debian_nanopi2

git clone https://github.com/friendlyarm/debian_nanopi2.git

2) Copy the Image and DTB files to replace the corresponding files under the "debian_nanopi2/boot/" directory
3) Generate boot.img

cd debian_nanopi2
mkdir rootfs
./build.sh

A newly generated boot.img will be under the "debian_nanopi2/sd-fuse_nanopi2/debian" directory.
The "mkdir rootfs" command creates a working directory for the build.sh script to run. It also creates some files such as "rootfs.img" but these files are useless.

Compile U-Boot

Download the U-Boot v2016.01 source code and compile it. Note that the github's branch is nanopi2-v2016.01:

git clone https://github.com/friendlyarm/u-boot.git 
cd u-boot
git checkout nanopi2-v2016.01
make make s5p6818_nanopi3_defconfig
make CROSS_COMPILE=aarch64-linux-

After your compilation succeeds a fip-nonsecure.img will be generated. If you want to test it flash it to your installation SD card to replace an existing U-Boot v2016.01 file via fastboot, sd-fuse_s5p6818 or eflasher ROM.
Note: you cannot use mixed U-Boot files. For example you cannot use fastboot to update an existing U-Boot V2014.07 and you cannot use bootloader.img to replace an existing u-boot.bin.

Compile Linux kernel 3.4.y

Prepare mkimage

You need the mkimage utility to compile a U-Boot source code package. Make sure this utility works well on your host before you start compiling a uImage.
You can install this utility by either commanding "sudo apt-get install u-boot-tools" or following the commands below:

cd uboot_nanopi2
make CROSS_COMPILE=arm-linux- tools
sudo mkdir -p /usr/local/sbin && sudo cp -v tools/mkimage /usr/local/sbin

Compile Linux Kernel

  • Download Kernel Source Code
git clone https://github.com/friendlyarm/linux-3.4.y.git
cd linux-3.4.y
git checkout nanopi2-lollipop-mr1

The NanoPC-T3's kernel source code lies in the "nanopi2-lollipop-mr1" branch.

  • Compile Android Kernel
make nanopi3_android_defconfig
touch .scmversion
make uImage
  • Compile Debian Kernel
make nanopi3_linux_defconfig
touch .scmversion
make uImage

After your compilation succeeds a uImage will be generated in the "arch/arm/boot/" directory. This kernel is for LCD output. You can use it to replace the existing uImage.
If you want to generate a kernel for HDMI output you need to run nanopi3_linux_hdmi_defconfig and do it this way:

make nanopi3_linux_hdmi_defconfig
touch .scmversion
make uImage

After your compilation succeeds a uImage.hdmi will be generated for HDMI 720P. If you want a uImage.hdmii for 1080P you can do it this way:

touch .scmversion
make nanopi3_linux_hdmi_defconfig
make menuconfig
  Device Drivers -->
    Graphics support -->
      Nexell Graphics -->
        [ ] LCD
        [*] HDMI
        (0)   Display In  [0=Display 0, 1=Display 1]
              Resolution (1920 * 1080p)  --->
make uImage

After your compilation succeeds a uImage.hdmi will be generated for HDMI 1080P. You can use it to replace the existing uImage.hdmi.

Use Your Generated Kernel

  • Update the kernel file in SD card

If you use an SD card to boot Android you can copy your generated uImage file to your SD card's boot partition(e.g. partition 1 /dev/sdX1).
If you use an SD card to Debian and you generated a uImage for an HDMI monitor you can use that uImage to replace the uImage.hdmi file in the SD card's boot partition. If you use an SD card to Debian and you generated a uImage for an LCD you can use that uImage to replace the uImage file in the SD card's boot partition.

  • Update Android kernel file in eMMC

If you want to update the kernel file in eMMC you need firstly boot your board, then mount eMMC's boot partition, replace the boot partition's kernel file with your generated one and reboot your board.
If you boot your board from eMMC you can update your kernel file by following the steps below:
1) After Android is loaded mount eMMC's boot partition (in our example eMMC's device name was /dev/mmcblk0p1) by using the following commands:

su
mount -t ext4 /dev/block/mmcblk0p1 /mnt/media_rw/sdcard1/

2) Connect your board to a host PC running Ubuntu with a MicroUSB cable and copy the uImage file to eMMC's boot partition by running the following commands

adb push uImage /mnt/media_rw/sdcard1/

3) Or you can copy your generated kernel file to an external storage card(e.g. an SD card or a USB drive), connect the storage card to your board the move the file from the card to eMMC's boot partition
4) After update is done type "reboot" and enter to reboot your board. Note: don't just directly disconnect your board from its power source or press the reset button to reboot the board. These actions will damage your kernel file

  • Update Debian kernel file in eMMC

If you boot your board from eMMC you can update your kernel file by following the steps below:
1) When Debian is being loaded eMMC's boot partition will be automatically mounted(in our example eMMC's device name was /dev/mmcblk0p1). You can use "mount" to verify that
2) Connect your board to a host PC via Ethernet and copy your generated uImage file via scp/ftp to eMMC's boot partition and replace the existing file. If your file is for LCD output use your uImage file to replace the existing uImage. If your file is for HDMI output use your uImage.hdmi file to replace the existing uImage.hdmi file
3) Or you can copy your generated kernel file to an external storage card(e.g. an SD card or a USB drive), connect the storage card to your board the move the file from the card to eMMC's boot partition
4) After update is done type in "reboot" to reboot your board. Note: don't just directly disconnect your board from its power source or press the reset button to reboot the board. These actions will damage your kernel file

  • Generate Your boot.img

If you want to generate an image file that can be flashed to eMMC you need to generate a boot.img file and copy it to your installation SD card
For Android copy the uImage file to Android source code's "device/friendly-arm/nanopi3/boot/" directory and compile this whole Android source code. After your compilation is successful you will get a boot.img file.
For Debian follow the steps below to generate a boot.img file
1) Download debian_nanopi2

git clone https://github.com/friendlyarm/debian_nanopi2.git

2) Copy the image file for an HDMI monitor and use it to replace the "debian_nanopi2/boot/uImage.hdmi" file and copy the image file for an LCD and use it to replace the "debian_nanopi2/boot/uImage" file
3) Generate Debian's boot.img

cd debian_nanopi2
mkdir rootfs
./build.sh

A newly generated boot.img will be under the "debian_nanopi2/sd-fuse_nanopi2/debian" directory.
The "mkdir rootfs" command creates a working directory for the build.sh script to run. It also creates some files such as "rootfs.img" but these files are useless.

Compile Kernel Modules

Android contains kernel modules which are in the "/lib/modules" directory in the system partition. If you want to add your own modules to the kernel or you changed your kernel configurations you need to recompile these new modules.
Compile Original Kernel Modules:

cd linux-3.4.y
make CROSS_COMPILE=arm-linux- modules

Here we have two new modules and we can compile them by running the commands below:

cd /opt/FriendlyARM/s5p6818/android
./vendor/friendly-arm/build/common/build-modules.sh

The "/opt/FriendlyARM/s5p6818/android" directory points to the top directory of Android source code. You can get more details by specifying option "-h".
After your compilation succeeds new modules will be generated

Compile U-Boot

Download the U-Boot source code and compile it. Note that the github's branch is nanopi2-lollipop-mr1:

git clone https://github.com/friendlyarm/uboot_nanopi2.git
cd uboot_nanopi2
git checkout nanopi2-lollipop-mr1
make s5p6818_nanopi3_config
make CROSS_COMPILE=arm-linux-

After compilation is done a u-boot.bin will be generated and you can update your NanoPC-T3's u-boot with fastboot by running the following commands:
1) On your host PC run "sudo apt-get install android-tools-fastboot" to installl the fastboot utility;
2) Connect your NanoPC-T3 to your host PC, boot your NanoPC-T3 and press "Enter" within two seconds right after your board is powered on and you will enter the u-boot commandline:
3) In the commandline window type "fastboot" and then press "Enter" to enter the fastboot mode:
4) Connect your NanoPC-T3 to a host PC with a MicroUSB cable and run the following commands in the commandline window to flash u-boot.bin to your NanoPC-T3:

fastboot flash bootloader u-boot.bin


Note:you cannot use "dd" to update your SD card in this situation.

Compile Android

  • Install Cross Compiler

Install 64 bit Ubuntu 16.04 on your host PC.

sudo apt-get install bison g++-multilib git gperf libxml2-utils make python-networkx zip
sudo apt-get install flex libncurses5-dev zlib1g-dev gawk minicom

For more details refer to https://source.android.com/source/initializing.html

  • Download Source Code

You need to use repo to get the Android source code. Refer to https://source.android.com/source/downloading.html

mkdir android && cd android
repo init -u https://github.com/friendlyarm/android_manifest.git -b nanopi3-lollipop-mr1
repo sync

The "android" directory is the working directory.

  • Compile System Package
source build/envsetup.sh
lunch aosp_nanopi3-userdebug
make -j8

After your compilation succeeds an image will be generated in the "out/target/product/nanopi3/" directory.

filename partition Description
boot.img boot -
cache.img cache -
userdata.img userdata -
system.img system -
partmap.txt - partition file
  • Flash Image to SD Card

If you want to boot your board from an SD card you need to copy your generated image file to the "sd-fuse_s5p6818 /android/" directory and flash it to your SD card with our script. For more details refer to # Make an Installation SD Card under Linux Desktop

  • Flash Image to eMMC

After compiling Android successfully you can flash it to eMMC with either of the following methods:
1) fastboot: right after the NanoPC-T2 is booted from eMMC press any key to enter the uboot commandline mode and type in "fastboot"
Connect your board to a host PC running Ubuntu with a USB cable and run the following commands in the PC's terminal:

cd out/target/product/nanopi3
sudo fastboot flash boot boot.img
sudo fastboot flash cache cache.img
sudo fastboot flash userdata userdata.img
sudo fastboot flash system system.img
sudo fastboot reboot

2) Use an SD Card
Copy these files: boot.img, cache.img, userdata.img, system.img, partmap.txt from the out/target/product/nanopi3 directory to your installation SD card's images/android directory and you can use this SD card to flash Android to eMMC.
