Work with ROCK 3 Ubuntu

Introduction to ROCK 3 Ubuntu

This guide is available for official ROCK 3 (ROCK 3A, Radxa CM3, etc) Ubuntu images.

ROCK 3 Ubuntu server is an easy to use system. While working with ROCK 3 Ubuntu Server, you will find it do well on playing music, Internet, BT, AI and so on.

ROCK 3 Ubuntu server 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/focal-testing/ focal 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/focal-stable/ focal main
deb http://apt.radxa.com/focal-testing/ focal 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

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

Check DDR size

ROCK 3 comes in several different DDR sizes, such as 1G, 2G, 4G, 8G, etc. Here shows 8GB RAM on ROCK 3A.

Storage device

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

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

LEDS

The two leds are configured as LED class devices, you can control them via /sys/class/leds/

Green: Flash twice per second after the kernel booting, it's called heartbeat.

Blue: On when there is power

You can change the behaviour of each LED by using the echo command on their trigger property.

root@rock-3c:/home/rock#  echo none > /sys/class/leds/user-led1/trigger 
root@rock-3c:/home/rock#  echo default-on > /sys/class/leds/user-led1/trigger 
root@rock-3c:/home/rock#  echo timer > /sys/class/leds/user-led1/trigger 
root@rock-3c:/home/rock#  echo heartbeat > /sys/class/leds/user-led1/trigger

You can use cat on the trigger property to list all the available values.

root@rock-3c:/home/rock# cat /sys/class/leds/user-led1/trigger 
none rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock

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 3A, ROCK 3B, Radxa CM3) part of Device Tree Overlays.

I2C

To enable I2C-2 (/dev/i2c-2), add item "rk3568-i2c2-m0" to the "overlays=" line.

 overlays=rk3568-i2c2-m0

To enable I2C-3 (/dev/i2c-3), add item "rk3568-i2c3-m0" to the "overlays=" line.

 overlays=rk3568-i2c3-m0

PWM

SPI

UART

System default enable uart2-m0 (/dev/ttyS2) to be debug console.

 overlays=rk3568-fiq-debugger-uart2m0

If you want to enable uart2-m0 (/dev/ttyS2) to be normal console, modify item "rk3568-uart2-m0" to the "overlays=" line.

 overlays=rk3568-uart2-m0

Test RTC Device

ROCK 3A is equipped with one RTC IC hym8563.

Firstly, plug in RTC battery to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.

Plug in power adaper to power on ROCK 3A.

And confirm that the rtc hym8563 device is created.

root@rock3a:~# dmesg | grep rtc
[    1.128345] rk808-rtc rk808-rtc: registered as rtc0
[    1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
[    2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1

Secondly, use the following commands to set the system time and synchronize it to rtc1.

root@rock3a:~# date -s "2021-08-17 20:00:00"
root@rock3a:~# hwclock -w -f /dev/rtc1
root@rock3a:~# hwclock -r -f /dev/rtc1
2021-08-17 20:00:04.745124+00:00
root@rock3a:~# poweroff

and then remove the power adapter.

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

root@rock3a:~# hwclock -r -f /dev/rtc1
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'

    : 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 recordding， 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 Ports

There are two USB 2.0 host ports and two USB 3.0 host ports.

Plug in U Disk and fire command lsblk. Here /dev/sda is related to U Disk.

root@rock-3a:~# lsblk
NAME         MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda            8:0    1 14.4G  0 disk

mmcblk0boot0 179:32   0    4M  1 disk 
mmcblk0boot1 179:64   0    4M  1 disk

Control PWM Fan

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

To control it, 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.

root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
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

+=== Test RTC Device ===
+ROCK 3A is equipped with one RTC IC hym8563.
+Firstly, plug in [[rock3/hardware/rtc | RTC battery]] to give power to RTC IC. Please note that we should keep the RTC battery in the RTC connector.
+Plug in power adaper to power on ROCK 3A.
+And confirm that the rtc hym8563 device is created.
+ root@rock3a:~# dmesg | grep rtc
+ [    1.128345] rk808-rtc rk808-rtc: registered as rtc0
+ [    1.130163] rk808-rtc rk808-rtc: setting system clock to 2017-08-04 09:00:05 UTC (1501837205)
+ [    2.801453] rtc-hym8563 5-0051: rtc core: registered hym8563 as rtc1
+Secondly, use the following commands to set the system time and synchronize it to rtc1.
+ root@rock3a:~# date -s "2021-08-17 20:00:00"
+ root@rock3a:~# hwclock -w -f /dev/rtc1

+-08-17 20:00:04.745124+00:00
+ root@rock3a:~# poweroff
+and then remove the power adapter.
+Finally, 10 minutes later we power on ROCK 3A via Type-C Port and check the rtc clock.
+ root@rock3a:~# hwclock -r -f /dev/rtc1
+-08-17 20:10:14.745124+00:00
+We see that rtc runs about 10 minutes also. That's good.
+===Test Audio Player===

+=== Control PWM Fan ===
+There is one 3-pin PWM Fan header on ROCK 3A/3B.
+To control it, 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.
+ root@rock-3a:~# cat /boot/uEnv.txt | grep overlays=
+ 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
