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, BT, 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

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.

root@rock-3a:~# free -h
              total        used        free      shared  buff/cache   available

Swap:            0B          0B          0B

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

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

The ROCK 3 system images use configuration file /boot/uEnv.txt or /boot/extlinux/extlinux.conf, if the system you use has /boot/uEnv.txt file, you can see the following, if the system you use has /boot/extlinux/extlinux.conf, please refer to this extlinu.conf setting.

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.

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'

mmcblk0boot1 179:64   0    4M  1 disk

Control PWM Fan

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

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/3C and confirm that the directory /sys/devices/platform/fe*.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/fe*.pwm/pwm/pwmchip*/export
root@rock-3a:~# echo 10000 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/period
root@rock-3a:~# echo 5000 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/duty_cycle
root@rock-3a:~# echo normal > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/polarity
root@rock-3a:~# echo 1 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
root@rock-3a:~# echo 0 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

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

Ethernet for ROCK 3B

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

+=== 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
+ root@rock3a:~# hwclock -r -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/3C.
+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/3C  and confirm that the directory '''/sys/devices/platform/fe*.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/fe*.pwm/pwm/pwmchip*/export
+ root@rock-3a:~# echo 10000 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/period
+ root@rock-3a:~# echo 5000 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/duty_cycle
+ root@rock-3a:~# echo normal > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/polarity
+ root@rock-3a:~# echo 1 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/enable # Turn on fan
+ root@rock-3a:~# echo 0 > /sys/devices/platform/fe*.pwm/pwm/pwmchip*/pwm0/enable # Turn off fan

-=== Test RTC Device ===
+  root@rock3c:~# apt-get update -y
+  root@rock3c:~# apt-get install -y broadcom-wifibt-firmware
-Firstly, plug in RTC battery and power on.Check the rtc device:
+  root@rock3c:~# vi /usr/bin/brcmbt_set_dev_fw.sh
-  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
--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
--08-17 20:10:14.745124+00:00
-We see that rtc runs about 10 minutes also. That's good.
