Work with ROCK 3 Debian

Introduction to ROCK 3 Debian

This guide is available for official ROCK 3 Debian images.

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.

Radxa APT

Radxa APT source includes stable one and testing one. Stable source includes stable packages while testing source includes latest but maybe unstable packages.

Radxa APT stable source is added by default while testing source is not added.

You can uncomment line like "deb http://apt.radxa.com/buster-testing/ buster main" in file /etc/apt/sources.list.d/apt-radxa-com.list to add testing source.

See file /etc/apt/sources.list.d/apt-radxa-com.list 

deb http://apt.radxa.com/buster-stable/ buster main
deb http://apt.radxa.com/buster-testing/ buster main

After adding testing source, you need to update APT and install your needed packages. 

$ sudo apt-get update

For more detail about Radxa APT, please see Radxa APT.

Upgrade necessary packages

Here is the example of upgrading rockchip-overlay and kernel packages. Pakcage linux-4.19-rock-3-latest provides the latest ROCK 3 kernel packages. 

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay
$ sudo apt-get install -y linux-4.19-rock-3-latest

NPU

SoC RK3566/RK3568 is equipped with 0.8TOPS NPU. See NPU Run Test to test it on your ROCK 3 boards.

General purpose input-output (GPIO)

  • ROCK 3 A has one 40-pin expansion header. To control them, see ROCK 3 A GPIO .

Common Hardware Interfaces, I2C, PWM, SPI, UART, CAN, etc

The ROCK 3 system images use configuration file /boot/uEnv.txt.

Warning: Remember there is only one line including item "overlays=" in file /boot/uEnv.txt.

To enable I2C, PWM, SPI, UART, CAN, etc, please see RK3566/RK3568 Available Overlay (ROCK 3 A, ROCK 3 B, Radxa CM3) part of Device Tree Overlays.

Check DDR size

ROCK 3 has several different DDR sizes, such as 2G, 4G, 8G, etc. Here it is 8G. 

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

Storage device

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

Test RTC Device

Firstly, 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)

Secondly, use the following commands to set the system time and synchronize it to rtc. 

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

and then disconnect the power supply

Finally, 10 minutes later we power on ROCK 3 A via Type-C Port and check the rtc clock. 

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

We see that rtc runs about 10 minutes also. That's good.

Test Audio Player

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

$ amixer -c 1 cset numid=1 3
   numid=1,iface=MIXER,name='Playback Path'
 ; type=ENUMERATED,access=rw------,values=1,items=11
 ; Item #0 'OFF'
 ; Item #1 'RCV'
 ; Item #2 'SPK'
 ; Item #3 'HP'
 ; Item #4 'HP_NO_MIC'
 ; Item #5 'BT'
 ; Item #6 'SPK_HP'
 ; Item #7 'RING_SPK'
 ; Item #8 'RING_HP'
 ; Item #9 'RING_HP_NO_MIC'
 ; Item #10 'RING_SPK_HP'
 : values=3

$ aplay -D plughw:1,0 test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

To test the Mic recording， please follow： 

$ amixer -c 1 cset numid=2 1
$ arecord -Dhw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav ./mic_test.wav      #this is a record command
  Recording WAVE './mic_test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ aplay -D plughw:1,0 mic_test.wav

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

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

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

Control PWM Fan

There is one 3-pin PWM Fan header on ROCK 3A/3B.

To control them, try the following steps.

  • Step 1: Add rk3568-pwm8-m0-fan overlay

You need to add the item "rk3568-pwm8-m0-fan" to line "overlays=" in file /boot/uEnv.txt. For example. 

overlays=rk3568-can1-m0 rk3568-pwm8-m0-fan
  • Step 2: Reboot ROCK 3A/3B and confirm that the directory /sys/devices/platform/fe6f0000.pwm related to pwm8 is created. 
root@rock-3a:~# ls /sys/devices/platform/fe6f0000.pwm
driver	driver_override  modalias  of_node  power  pwm	subsystem  uevent
  • Step 3: Set PWM period, duty_cycle, polarity and enable with root permission. 
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe6f0000.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

Ethernet

3A Ethernet

ROCK 3A is equipped with one 1G Ethernet port. 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

3B Ethernet

ROCK 3B is equipped with two 1G Ethernet ports. You can use two network cable (one end connected to the external network port or route) to connect your ROCK 3B to the network. The ROCK 3B 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 card, eth0 and eth1, 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
$ sudo dhclient eth1

CM3 IO Ethernet

CM3 IO is equipped with one 1G Ethernet port. You can use a network cable (one end connected to the external network port or route) to connect your CM3 IO to the network. CM3 IO 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
