With the new system release, the existing documentations are out of date.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

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
Ethernet Test Result

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.

Play songs and have a good time.
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 sleep 0.2 echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable
Raspberry Pi 7 Inch Touchscreen
CPU Overclocking
MIPI CSI Camera
Radxa Display 10HD
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
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 #intfc:dtoverlay=spi1-flash
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
