Work with Rock Pi 4 Ubuntu Server
Introduction
The Ubuntu server image for Rock Pi 4 target for minimal, fast and customization.
Create Image
Linux as root or use Etcher in Windows
gunzip -c rockpi4b-ubuntu-bionic-minimal-20190104_2101-gpt.img.gz | dd of=/dev/mmcblk0
Default username/password
default username: rock default password: rock
rock is sudo user and switch to root can be done with the following command as user rock:
sudo su
Access from the Host PC/Laptop
Option 1: Serial console
Check Serial Console
Option 2: SSH
SSH server is enabled on port 22 of ROCK Pi 4 default image.
Please use angryip to find your board IP address.
$ ping ip-of-device $ ssh rock@ip-of-device
Add Radxa APT
Follow the Guide of Radxa APT to add Radxa APT.
We suggest that you add bionic-testing APT Source to get the newest packages.
Network Connection
There are two methods for network connection. One is Ethernet and the other is WIFI.
Ethernet Connection
You can use a network cable (one end connected to the external network port or route) to connect your ROCK Pi 4 to the network. The ROCK Pi 4 will automatically configure the network for your surfing on the Internet.
To test the Ethernet, we need to follow the steps:
- Switch to super user mode by command
$ sudo su
- Check whether the Ethernet is normal by command, ifconfig, which would show us a network card, eth0, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.
$ ifconfig $ ping www.baidu.com
WIFI Connection
When there is not a network cable for your ROCK Pi 4 the WIFI connection is another good choice. ROCK Pi 4 supports 2.4G/5G WIFI wireless network.
To test the WIFI performance, we need to follow the steps:
- Switch to super user mode
$ sudo su
- Open the WIFI
$ nmcli r wifi on
- Scan WIFI
$ nmcli dev wifi
- Connect to WIFI network
$ nmcli dev wifi connect "wifi_name" password "wifi_password"
- Test WIFI perpormance by tool iperf.
Bluetooth
Update necessary packages
$ sudo apt-get update $ sudo apt-get install -y rockchip-fstab rockchip-overlay $ sudo apt-get install -y linux-4.4-latest # kernel version(>=4.4.154.100) $ sudo apt-get install -y broadcom-wifibt-firmware(>=0.6)
Check bluetooth service
$ systemctl status bluetooth
Run bluetooth service
$ systemctl start bluetooth
Check bluetooth device
$ hciconfig hci0: Type: Primary Bus: UART BD Address: AD:B8:A0:DA:A3:27 ACL MTU: 1021:8 SCO MTU: 64:1 UP RUNNING RX bytes:7900 acl:35 sco:0 events:387 errors:0 TX bytes:217746 acl:380 sco:0 commands:102 errors:0
Example: Connect to Bluetooth Speaker
Install pulseaudio packages
$ sudo apt-get install -y pulseaudio-module-bluetooth pulseaudio
Run pulseaudio, otherwise ROCK Pi 4 will not be able to connect to device.
$ pulseaudio --start
Connect using bluetoothctl
$ bluetoothctl [bluetooth]# default-agent Default agent request successful [bluetooth]# power on Changing power on succeeded [bluetooth]# scan on Discovery started [bluetooth]# trust 77:EC:79:4F:6B:AC [CHG] Device 77:EC:79:4F:6B:AC Trusted: yes Changing 77:EC:79:4F:6B:AC trust succeeded [bluetooth]# pair 77:EC:79:4F:6B:AC Attempting to pair with 77:EC:79:4F:6B:AC [CHG] Device 77:EC:79:4F:6B:AC Connected: yes [CHG] Device 77:EC:79:4F:6B:AC UUIDs: 00001101-0000-1000-8000-00805f9b34fb [CHG] Device 77:EC:79:4F:6B:AC UUIDs: 0000110b-0000-1000-8000-00805f9b34fb [CHG] Device 77:EC:79:4F:6B:AC UUIDs: 0000110c-0000-1000-8000-00805f9b34fb [CHG] Device 77:EC:79:4F:6B:AC UUIDs: 0000110e-0000-1000-8000-00805f9b34fb [CHG] Device 77:EC:79:4F:6B:AC UUIDs: 0000111e-0000-1000-8000-00805f9b34fb [CHG] Device 77:EC:79:4F:6B:AC ServicesResolved: yes [CHG] Device 77:EC:79:4F:6B:AC Paired: yes Pairing successful [bluetooth]# connect 77:EC:79:4F:6B:AC Attempting to connect to 77:EC:79:4F:6B:AC [CHG] Device 77:EC:79:4F:6B:AC Connected: yes Connection successful [CHG] Device 77:EC:79:4F:6B:AC ServicesResolved: yes

General purpose input-output (GPIO)
- ROCK Pi 4 has one 40-pin expansion header. To control them, see ROCK Pi 4 GPIO Pinout.
Common Hardware Interfaces, I2C, PWM, SPI, UART, etc
The ROCK Pi 4 system images use hw_intfc.conf, provided by the package rockpi4-dtbo, to configure interfaces.
For more details about device tree overlays, see ROCK Pi 4 Device Tree Overlays.
Install essential package
sudo apt-get install -y rockpi4-dtbo
I2C
Modify file /boot/hw_intfc.conf. Set "on" to enable the optional hardware interfaces while set "off" to disable.
intfc:i2c2=on intfc:i2c6=on intfc:i2c7=on
PWM
Modify file /boot/hw_intfc.conf. Set "on" to enable the optional hardware interfaces while set "off" to disable.
intfc:pwm0=on intfc:pwm1=on
SPI
Modify file /boot/hw_intfc.conf. Set "on" to enable the optional hardware interfaces while set "off" to disable.
intfc:spi1=on intfc:spi2=on intfc:dtoverlay=devspi1 intfc:dtoverlay=devspi2
UART
Modify file /boot/hw_intfc.conf. Set "on" to enable the optional hardware interfaces while set "off" to disable.
intfc:uart2=on intfc:uart4=on
Debug console
Modify file /boot/hw_intfc.conf. Set ttyS2 as debug console.
Disable UART2
intfc:uart2=off
And uncomment the following line.
intfc:dtoverlay=console-on-ttyS2
Use SPI Flash on board
Modify file /boot/hw_intfc.conf. Disable UART4 and enable SPI1. Besides, need to load spi1-flash overlay.
intfc:uart4=off intfc:spi1=on intfc:dtoverlay=spi1-flash
Additional software
OpenCV
There are two ways to get OpenCV. One is building OpenCV by yourself (Option one) and the other is installing opencv4.0 package (Option two).
Option 1: Manually build
Build OpenCV by yourself. See Install OpenCV.
Option 2: Install pre-built binaries
Install Ubuntu desktop
To use OpenCV, an OS desktop is necessary. If your ROCK Pi 4 is running Ubuntu but without desktop, you can install Ubuntu mate desktop.
$ sudo apt install ubuntu-mate-core && sudo apt install ubuntu-mate-desktop
Install all the recommended packages
Required:
$ sudo apt-get update && sudo apt-get upgrade $ sudo apt-get install build-essential $ sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
Recommended optional packages:
$ sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev $ sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libavresample-dev $ sudo apt install tesseract-ocr cmake-data liblept5
Install OpenCV package:
$ sudo apt-get install opencv4.0
Step 3: Test OpenCV
To check the version of your installed OpenCV, try this:
rock@linux:~$ python Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15) [GCC 7.3.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import cv2 >>> cv2.__version__ '4.0.1' >>>
Obtain OpenCV sample:
$ cd ~ $ wget -O opencv.zip https://github.com/opencv/opencv/archive/4.0.1.zip $ unzip opencv.zip $ cd ~/opencv-4.0.1/samples/python $ python watershed.py
OpenGL ES
Install glmark2
$ sudo apt update $ sudo apt install -y git gcc g++ libpng-dev libjpeg-dev pkg-config libx11-dev libdrm-dev libgbm-dev libgbm1 libudev-dev $ mkdir -p /home/rock/work $ cd /homne/rock/work $ git clone https://github.com/glmark2/glmark2.git $ ./waf configure --with-flavors=drm-glesv2 $ ./waf build -j 4 $ ./waf install
