    ROCK Pi S >  Ubuntu

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, Bluetooth 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 rockpis-dtbo
 $ sudo apt-get install -y rtl8723ds-firmware rockchip-adb 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.

Bluetooth

Update necessary packages

 $ sudo apt-get update
 $ sudp apt-get install -y rockchip-overlay
 $ sudo apt-get install -y linux-4.4-rockpis-latest # kernel version(>=4.4.143.27)
 $ sudo apt-get install -y rtl8723ds-firmware bluez

Check Bluetooth service

 $ systemctl status bluetooth

Run Bluetooth service if the Bluetooth service is inactive.

 $ systemctl start bluetooth

Check Bluetooth device

 $ hciconfig
 hci0:   Type: Primary  Bus: UART
         BD Address: 22:22:AA:25:49:1E  ACL MTU: 1021:8  SCO MTU: 255:12
         UP RUNNING 
         RX bytes:4424 acl:0 sco:0 events:81 errors:0
         TX bytes:3820 acl:0 sco:0 commands:52 errors:0

Example: Connect to Bluetooth Speaker.

Change to root mode.

 $ sudo su

Install pulseaudio packages

 # apt-get install -y pulseaudio-module-bluetooth pulseaudio

Run pulseaudio

 # pulseaudio --start

Connect using bluetoothctl

 # bluetoothctl
 [bluetooth]# default-agent 
 [bluetooth]# power on
 [bluetooth]# scan on
 [bluetooth]# trust 77:EC:79:4F:6B:AC
 [bluetooth]# pair 77:EC:79:4F:6B:AC
 [bluetooth]# connect 77:EC:79:4F:6B:AC

Play songs and enjoy it.

Common Hardware Interfaces, I2C, 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-i2c3

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 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 ttyS0, ttyS1 and ttyS2 as common serial communication devices, add these items "rk3328-uart0", "rk3328-uart1" and "rk3328-uart2" to the "overlays=" line. The device /dev/ttyS0, /dev/ttyS1, /dev/ttyS2, are available.

 overlays=rk3308-uart0 rk3308-uart1 rk3308-uart2
