Work with ROCK Pi S Ubuntu
Introduction to ROCK Pi S Ubuntu
ROCK Pi S Ubuntu is an easy to use system. While working with ROCK Pi S Ubuntu, you will find it do well on playing music, Internet, BT and so on.
ROCK Pi S Ubuntu uses systemd to manage system.
Access from the Host PC/Laptop
Option 1: USB access(adb)
By default, the ROCK Pi S Linux image enables adbd services, which is a debug bridge from Android now ported on Linux. With one USB A to C cable you can power and access the board, very handy.
To use adb, you need to install adb tool on the PC/Laptop. Check instructions for Windows and Linux.
After you have adb installed successfully, run the following command on console to login the shell of ROCK Pi S:
adb shell
Check Using adb.
Option 2: Serial console
Check Serial Console
Option 3: SSH
SSH server is enabled on port 22 of ROCK Pi S default image.
Please use angryip to find your board IP address.
To access ROCK Pi S by SSH, try
ping rockpis.local ssh rock@rockpis.local
or if your router/network doesn't support Local Domain, you need to check your network/router administrator page and look for the ROCK Pi S ip address.
ping ip-of-device ssh rock@ip-of-device
Note: You can also get the IP of ROCK Pi S from option 1 or option 2 if you can not access network administrator page.
Default User Account
Non-root User:
User Name : rock Password : rock
Update necessary packages
Add Radxa APT, see Radxa APT.
Install packages:
$ sudo apt-get update $ sudo apt-get install -y apt-utils # without this, the adb connection might break during installation of rockchip-adb $ sudo apt-get install -y rockchip-overlay $ sudo apt-get install -y linux-4.4-rockpis-latest $ sudo apt-get install -y rtl8723ds-firmware rockchip-adbd resize-assistant $ sudo apt-get install -y rockpis-dtbo # For those ROCK Pi S system images released before March 1st, 2020
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 S to the network. The ROCK Pi S 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
- If failed to connect to a normal domain. , try
$ sudo dhclient eth0
WIFI Connection
When there is not a network cable for your ROCK Pi S the WIFI connection is another good choice. ROCK Pi S supports 2.4G 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.
BT
Update necessary packages.

Play songs and enjoy it.
Common Hardware Interfaces, I2C, PWM, SPI, UART, etc
The ROCK Pi S system images released before March 1st, 2020 use hw_intfc.conf to configure interfaces while those which released after March 1st, 2020 use uEnv.txt. We suggest that you use the latest system images.
Warning: Remember there is only one line including item "overlays=" in file /boot/uEnv.txt.
For more details about device tree overlays, see Device Tree Overlays and ROCK Pi S Libmraa.
I2C
To enable I2C-0 (/dev/i2c-0), add item "rk3308-i2c0" to the "overlays=" line.
overlays=rk3308-i2c0
To enable I2C-1 (/dev/i2c-1), add item "rk3308-i2c1" to the "overlays=" line.
overlays=rk3308-i2c1
To enable I2C-2 (/dev/i2c-2), add item "rk3308-i2c2" to the "overlays=" line.
overlays=rk3308-i2c2
To enable I2C-2 (/dev/i2c-3), add item "rk3308-i2c3" to the "overlays=" line.
overlays=rk3308-i2c3m0 or rk3308-i2c3m1
PWM
To enable PWM1, add item "rk3308-pwm1" to the "overlays=" line.
overlays=rk3308-pwm1
To enable PWM2, add item "rk3308-pwm2" to the "overlays=" line.
overlays=rk3308-pwm2
To enable PWM3, add item "rk3308-pwm3" to the "overlays=" line.
overlays=rk3308-pwm3
SPI
To enable SPI2, add item "rk3308-spi-spidev" to the "overlays=" line.
overlays=rk3308-spi-spidev param_spidev_spi_bus=2 param_spidev_spi_cs=0 param_spidev_max_freq=10000000
To enable SPI1, add item "rk3308-spi-spidev" to the "overlays=" line.
overlays=rk3308-spi-spidev param_spidev_spi_bus=1 param_spidev_spi_cs=0 param_spidev_max_freq=10000000
UART
The debugger console baud rate options: 1500000n8 and 115200n8.
To disable debugger console, just need to delete "console=" line in file /boot/uEnv.txt.
To set ttyS0 as debugger console, add item "rk3308-uart0" to the "overlays=" line. Also need to set console value.
console=ttyS0,1500000n8 overlays=rk3308-uart0
To set ttyS1 as debugger console, add item "rk3308-uart1" to the "overlays=" line. Also need to set console value.
console=ttyS1,1500000n8 overlays=rk3308-uart1
To set ttyS2 as debugger console, add item "rk3308-uart2" to the "overlays=" line. Also need to set console value.
console=ttyS2,1500000n8 overlays=rk3308-uart2
To set ttyS3 as debugger console, add item "rk3308-uart3" to the "overlays=" line. Also need to set console value.
console=ttyS3,1500000n8 overlays=rk3308-uart3
To set ttyS0, ttyS1 ,ttyS2 and ttyS3 as common serial communication devices, add these items "rk3328-uart0", "rk3328-uart1","rk3328-uart2" and "rk3328-uart3" to the "overlays=" line. The device /dev/ttyS0, /dev/ttyS1, /dev/ttyS2,/dev/ttyS3, are available.
overlays=rk3308-uart0 rk3308-uart1 rk3308-uart2 rk3308-uart3
USB
USB port, working in host mode, enables the attachment of peripherals such U Disk, keyboards, mice, USB dongle like USB camera, etc.
USB port, working in OTG mode, supports USB gadget function including adb, USB RNDIS, USB subnet etc.
There are two USB ports on ROCK Pi S. One is Type-A port and the other is Type-C port. By default, on Ubuntu system Type-A port is working in host mode. Type-C port is configured in OTG mode. With software configuration, Type-C port can also work in host mode.
