This page is currently out-dated

With the new system release, the existing documentations are out of date. We are currently in the process of updating the documentation, so please only taking the rest of this page as a general guideline.

Some key differences are:

The default account is now radxa/radxa
SSH is disabled by default.

This setting can be overridden by first flash the image to microSD card, then edit before.txt in config partition on your microSD card, and add enable_service ssh at end of the file.

Bluetooth firmware are now included.
You can use rsetup to manage overlays.

How to use Debian

Introduction of ROCK 4 Debian

ROCK 4 Debian is an easy to use desktop system. While working with ROCK 4 Debian, you will find it do well on playing music, Internet, BT, AI and so on.

ROCK 4 Debian uses systemd to manage system.

Command prepended by $ means the command may be executed by an unprivileged user. And command prepended by # means the command may be executed by an privileged user. But the symbol, $ or #, is not part of the command.

Debian Default User Account

Non-root User:

User Name : rock
Password  : rock

or

User Name : linaro
Password  : linaro

Root mode

rock is sudo user and switch to root can be done with the following command as user rock:

sudo su

For example:

rock@rockpi-4b:~$ 
rock@rockpi-4b:~$ sudo su
[sudo] password for rock: 
root@rockpi-4b:/home/rock#

There is no password for root user by default. You can set the password via 'passwd root'.

root@rockpi-4b:/home/rock# passwd root
New password: 
Retype new password: 
passwd: password updated successfully
root@rockpi-4b:/home/rock#

Access from the Host PC/Laptop

Option 1: HDMI monitor and Mouse

You would see Desktop on HDMI monitor.

Option 2: SSH

SSH server is enabled on port 22 of ROCK default image.

Please use angryip to find your board IP address.

$ ping ip-of-device
$ ssh rock@ip-of-device

Option 3: Serial console

Check Serial Console

Setting time zone

Change time zone (default time is UTC(Universal Time Coordinated) time, this example is how changed it to CST(China Standard Time)):

# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

Network Connection

There are two methods for network connection, Ethernet and WiFi.

Ethernet Connection

You can use a network cable (one end connected to the external network port or route) to connect your ROCK 4 to the network. The ROCK 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. Here result shows us a network card, eth0, and the Ethernet IP address, 192.168.2.121. Also, use tool, ping, to connect to a normal domain.

 $ ifconfig eth0

root@rockpi-4b:/home/rock# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.121  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 240e:3b7:3245:f180::76a  prefixlen 128  scopeid 0x0<global>

        inet6 fe80::5399:857f:dd31:867d  prefixlen 64  scopeid 0x20<link>
        inet6 fd02::940b:e7cd:38f0:55bd  prefixlen 64  scopeid 0x0<global>
        ether 76:ca:5e:be:5a:f4  txqueuelen 1000  (Ethernet)
        RX packets 73011  bytes 10568786 (10.0 MiB)
        RX errors 0  dropped 3  overruns 0  frame 0
        TX packets 903  bytes 80931 (79.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 24

 $ ping www.baidu.com -I eth0

To check the bandwidth, we need another machine, Host Linux (example). Here we use ROCK 4 Desktop as a server, and Host Linux as a client
- Make sure there is iperf3 tool on your host PC. Maybe you can get it by $ sudo apt-get update, and $ sudo apt-get install iperf3
- At the Debian terminal, execute the command, $ iperf3 -s
- At the Host Linux terminal, execute the command, $ iperf3 -c 192.168.2.121

iperf Done.

You see, The Bandwidth of Ethernet is up to nearly 1000Mbits/sec. Of course, you are encouraged to set ROCK 4 Debian as a client and Host Linux as a server when testing Ethernet network performance.

WiFi Connection

When there is not a network cable for your ROCK 4, the WiFi connection is another good choice. ROCK 4 supports 2.4G and 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 iperf3.

Work with PCIe M.2 NVME SSD

Before supplying power for ROCK 4 board, connect a Samsung EVO 960 SSD to ROCK 4 Board.

Running the following commands to use the M.2 NVME SSD. Here we use a newly launched M.2 SSD.

Switch to super user mode

 $ sudo su

Check NVME devices.The character device /dev/nvme0 is the NVME device controller, and block devices like /dev/nvme0n1 are the NVME storage namespaces. Devies like /dev/nvmen0n1 are the actual storage, which will behave essentially as disks.

 # ls /dev/nvme*

If there is not partition in NVME device, need to use tool fdisk to create one.

 # fdisk /dev/nvme0n1

If create partition successfully, there should be at least one partition, /dev/nvme0n1p1. Then create a file system, like:

# mkfs.ext4 /dev/nvme0n1p1

Finally, mount the file system. You can absolutely create a new directory to be a mounted point.

 # mount /dev/nvme0n1p1 /mnt

Remember, if you have a M.2 SSD that have already stored data, you just need to mount it.

Improve NVMe speed

By default, the PCIe of ROCK Pi 4 runs on Gen1 mode for the most capability. Once you confirm that your NVMe works well you can try to enable the PCIe gen2 mode to get the max speed of NVMe(reading/writing > 1000MB/s).

To enable PCIe gen2 mode, make sure your /boot is mounted:

mount | grep boot

Edit /boot/hw_intfc.conf, uncomment the line:

intfc:dtoverlay=pcie-gen2

save and reboot. You should have higher speed on NVMe.

HDMI

ROCK 4 Supports HDMI 4K.

DP

ROCK Pi 4C supports HDMI and DP at the same time.

Hardware configuration

Fan

To control ROCK 4C Plus fan, please use the following commands.

echo 0 > /sys/class/pwm/pwmchip0/export
sleep 0.2
echo 40000 > /sys/class/pwm/pwmchip0/pwm0/period
sleep 0.2
echo 10000 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
sleep 0.2
echo normal >  /sys/class/pwm/pwmchip0/pwm0/polarity

ROCK 4C Plus Debian supports Radxa Display 10HD Radxa Display 10HD.

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

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

And add "#" to line "intfc:dtoverlay=console-on-ttyS2"

 #intfc:dtoverlay=console-on-ttyS2
 #intfc:dtoverlay=console-on-ttyS4

Please note that when ROCK Pi 4 uart2 is connected with your devices like Raspberry Pi CAN/RS485 hat sending some data to uart2 on ROCK Pi 4. Please do the following step.

Check the file /boot/extlinux/extlinux.conf. And delete the following line.

menu title select kernel

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

Use glmark2-es2-drm

If there is no tool glmark2-es2, you can build one from source code.

Here is the example of building glmark2-es2-drm.

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 /home/rock/work
 $ git clone https://github.com/glmark2/glmark2.git
 $ cd glmark2/
 $ ./waf configure --with-flavors=drm-glesv2
 $ ./waf build -j 4
 $ ./waf install

Test OpenGL via glmark2-es2-drm

Change to console mode via 'Ctrl + Alt + F2'

And run the following commands:

 $ glmark2-es2-drm

Audio Test

Use Go

Go(also golang) runs well on Debian. To get golang do:

 $ sudo su
 $ apt-get update
 $ apt-get install golang

Use Editor Emacs

Emacs runs well on Debian. To get emacs do:

 $ sudo su
 $ apt-get update
 $ apt-get install emacs

You can start the program by command line or clicking on the Emacs Icon.

 $ emacs

+With the new system release, the existing documentations are out of date. We are currently in the process of updating the documentation, so please only taking the rest of this page as a general guideline.
+Some key differences are:
+* The default account is now '''radxa/radxa'''
+* SSH is disabled by default.
+This setting can be overridden by first flash the image to microSD card, then edit '''before.txt''' in '''config''' partition on your microSD card, and add <code>enable_service ssh</code> at end of the file.
