==== Option 1: Serial console ====
 +
 +
Check [[rockpi4/dev/serial-console | Serial Console]]
 +
 +
==== Option 2: SSH ====
 +
SSH server  is enabled on port 22 of ROCK Pi 4 default image.
 +
 +
Please use [https://angryip.org/ angryip] to find your board IP address.
 +
 +
$ ping ip-of-device
 +
$ ssh rock@ip-of-device
 +
 +
=== Add Radxa APT ===
 +
 +
Follow the [https://wiki.radxa.com/Rockpi4/radxa-apt#Introduction 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.

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.

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
