Work with ROCK 3 Debian

Introduction to ROCK 3 Debian

ROCK 3 Debian is an easy to use desktop system. While working with ROCK 3 Debian, you will find it do well on playing music, Internet, Bluetooth, AI and so on.

ROCK 3 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.

Access from the Host PC/Laptop

Option 1: Serial console

Check Serial Console

Option 2: SSH

SSH server is enabled on port 22 of ROCK 3 default image.

Please use angryip to find your board IP address.

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

Debian Default User Account

Non-root User:

User Name : rock
Password  : rock

Desktop

The preinstalled Desktop is xfce4.

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-rock-3-latest

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 3 to the network. The ROCK 3 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 3 the WIFI connection is another good choice. ROCK Pi N10 supports 2.4G/5G WIFI and WIFI 6 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.

Check DDR size

ROCK 3 has several different DDR sizes, such as 2G, 4G, 8G.

$ free -h
              total        used        free      shared  buff/cache   available
Mem:          7.4Gi        72Mi       7.1Gi        16Mi       182Mi       7.2Gi 
Swap:            0B          0B          0B

For example, the size of DDR on this board is 8G.

Storage device

eMMC: /dev/mmcblk0
uSD Card: /dev/mmcblk1
NVME M.2 SDD: /dev/nvme0n1

Test RTC Device

First, plug in RTC battery and power on.Check the rtc device:

root@rock3a:~# dmesg | grep rtc
[    0.749597] rk808-rtc rk808-rtc: registered as rtc0
[    0.751404] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:02 UTC (1501837202)

Second, use the follow commands to set the system time and synchronization to the rtc clock.

$ date -s "2021-08-17 20:03:00"
$ hwclock -w
$ hwclock -r
root@rock3a:~# hwclock -r
2021-08-17 20:00:04.745124+00:00
$ poweroff

and then disconnect the power supply Third, back to power after 10 mins and check whether the rtc clock run the same time

$ hwclock -r
root@rock3a:~# hwclock -r
2021-08-17 20:10:14.745124+00:00

Test Audio Player

Download a wav audio file, and use the command to test.

$ aplay -D plughw:1,0 test.wav

root@rock3a:~# aplay -D plughw:1,0 6.wav 
xcb_connection_has_error() returned true 
Playing WAVE '6.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Test USB Host

Plug in the U dish and use the command by serial console.

$ dmesg | tail
[  133.773558] usb 2-1: SerialNumber: CCYYB18M1CFKO4H4
[  133.774332] usb-storage 2-1:1.0: USB Mass Storage device detected

$ sudo mount /dev/sda1 /mnt
$ lsblk
root@linaro-alip:~# lsblk

└─sda1         8:1    1 14.7G  0 part /mnt

If /dev/sda1 is successfully mounted, this usb host is working properly.
