Work with ROCK Pi E Debian

Introduction to ROCK Pi E Debian

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

ROCK Pi E Debian uses systemd to manage system.

Here Need one USB to TTL serial cable. Or use SSH.

Debian Default User Account

Non-root User: 

   User Name : rock
   Password  : rock

Install and update necessary packages

Add Radxa APT, see Radxa APT.

Install packages; 

 $ sudo apt-get update
 $ sudo apt-get install -y rockchip-overlay
 $ sudo apt-get install -y linux-4.4-rockpie-latest

Install xfce4 desktop

 $ sudo apt-get install -y xfce4
 $ sudo apt-get install -y xfce4-goodies task-xfce-desktop lightdm dialog tango-icon-theme

Network Connection

There are two methods for network connection. One is Ethernet and the other is WIFI.

Ethernet Connection

ROCK Pi E provides dual ethernets. You can use two network cables at the same time to connect your ROCK Pi E to the network. The ROCK Pi E 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 two network cards, eth0 and eth1, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain. 
 $ ifconfig
 $ ping -I eth0 www.baidu.com
 $ ping -I eth1 www.baidu.com

WIFI Connection

When there is not a network cable for your ROCK Pi E the WIFI connection is another good choice. ROCK Pi E 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

To gain a stronger signal, you need an antenna attached to the antenna socket on board.

Update necessary packages 

 $ sudo apt-get update
 $ sudp apt-get install -y rockchip-overlay
 $ sudo apt-get install -y linux-4.4-rockpie-latest # kernel version(>=4.4.194-7-rockchip)
 $ sudo apt-get install -y realtek-bt-firmware bluez

Check BT service 

 $ systemctl status bluetooth

Run BT service if the BT service is inactive. 

 $ systemctl start bluetooth

Start realtek-btfw-load service 

 $ systemctl start realtek-btfw-load

Check BT device 

 $ hciconfig
 hci0:   Type: Primary  Bus: USB
         BD Address: 74:EE:2A:55:23:F7  ACL MTU: 1021:8  SCO MTU: 255:12
         UP RUNNING 
         RX bytes:40357 acl:34 sco:0 events:814 errors:0
         TX bytes:216782 acl:379 sco:0 commands:101 errors:0

Example: Connect to BT 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 E system images use /boot/uEnv.txt to configure hardware interfaces.

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.

I2C

To enable I2C-1 (/dev/i2c-1), add item "rk3328-i2c1" to the "overlays=" line. 

 overlays=rk3328-i2c1

SPI

To enable SPI0, add item "rk3328-spi-spidev" to the "overlays=" line. 

 overlays=rk3328-spi-spidev
 param_spidev_spi_bus=0
 param_spidev_spi_cs=0
 param_spidev_max_freq=10000000

UART

The debugger console baud rate options: 1500000n8 and 115200n8.

To set ttyS1 as debugger console, add item "rk3328-uart1" to the "overlays=" line. Also need to set console value. 

 console=ttyS1,1500000n8
 overlays=rk3328-uart1

To set ttyS2 as debugger console, add item "rk3328-uart2" to the "overlays=" line. Also need to set console value. 

 console=ttyS2,1500000n8
 overlays=rk3328-uart2

To set ttyS1 as common serial communication, add item "rk3328-uart1" to the "overlays=" line. The device /dev/ttyS1 is available. 

 overlays=rk3328-uart1

To set ttyS2 as common serial communication, add item "rk3328-uart2" to the "overlays=" line. The device /dev/ttyS2 is available. 

 overlays=rk3328-uart2
Example for UART communication

Step one. Hardware connection. 

 UART1_TXD <---> UART2_RXD
 UART1_RXD <---> UART2_TXD

Step two. Use ssh to access ROCK Pi E.

Step three. Enable UART1 and UART2 via adding the following line to file /boot/uEnv.txt. 

 overlays=rk3328-uart1 rk3328-uart2

Also disable console via removing the following line in file /boot/uEnv.txt. 

 console=ttyS2,1500000n8

Step four. Reboot the device.

Step five. Use ssh to access ROCK Pi E. Set up SSH terminal one and two.

In terminal one. 

 $ sudo su
 # stty -F /dev/ttyS1 9600
 # cat /dev/ttyS1

In terminal two. 

 $ sudo su
 # stty -F /dev/ttyS2 9600
 # echo "hello rock pi e" > /dev/ttyS2

In terminal one, we would see the following string. 

 hello rock pi e
