Introduction to ROCK 5 Debian

This guide is available for official ROCK 5 Debian images.

ROCK 5 Debian is an easy to use desktop system. While working with ROCK 5 Debian, you will find it do well on playing music, Internet, BT, AI and so on.

ROCK 5 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.

List of boards supported

• ROCK 5B

Access from the Host PC/Laptop

Option 1: HDMI monitor and Mouse

You would see Desktop on HDMI monitor.

Option 2: Serial console

See Serial Console

Option 3: SSH

SSH server is enabled on port 22 of ROCK 5 default image.

Please use angryip to find your board IP address.

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

Default User Account

Non-root User:

User Name : rock
Password  : rock

Switch to root user

rock is sudo user and switch to root can be done with the following command as user rock:

sudo su

For example:

rock@rock-5b:~$ 
rock@rock-5b:~$ sudo su
[sudo] password for rock: 
root@rock-5b:/home/rock# 

There is no password for root user by default. You can set the password via 'passwd root'.

root@rock-5b:/home/rock# passwd root
New password: 
Retype new password: 
passwd: password updated successfully
root@rock-5b:/home/rock#

RTC Device

ROCK 5B 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 5B.

And confirm that the rtc hym8563 device is created.

root@rock-5b:/home/rock#  dmesg | grep rtc
[    6.407133] rtc-hym8563 6-0051: rtc information is valid
[    6.412731] rtc-hym8563 6-0051: registered as rtc0
[    6.413779] rtc-hym8563 6-0051: setting system clock to 2022-06-22T01:22:26 UTC (1655860946)

Secondly, use the following commands to set the system time and synchronize it to rtc0.

root@rock-5b:/home/rock# hwclock -r
2021-06-12 08:10:02.613381+08:00
root@rock-5b:/home/rock# date
Wed Jun 22 10:06:10 CST 2022
root@rock-5b:/home/rock# hwclock -w
root@rock-5b:/home/rock# hwclock -r 
root@rock-5b:/home/rock# poweroff

take the RTC battery off，after 10minute or longer，insert the rtc battery and power on rock5b，check whether the RTC is synchronized with the system clock

root@rock-5b:/home/rock# hwclock -r

System update

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

/boot/config.txt

/boot/config.txt is designed for kernel parameters and hardware configuration. Please note that execute "update_extlinux.sh" after changing file /boot/config.txt.

kernel parameters

kernel command line: started with "cmdline:"

For example:

# For console
cmdline: earlycon=uart8250,mmio32,0xfeb50000 console=ttyFIQ0 console=tty1 consoleblank=0 loglevel=7
# For rootfs
cmdline: panic=10 rootwait rw init=/sbin/init rootfstype=ext4

device tree overlay

dt overlay line: started with "dtoverlay=". One dt overlay one line.

For example:

dtoverlay=rk3588-uart7-m2

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

The ROCK 5 system images use configuration file /boot/config.txt. Please note that execute "update_extlinux.sh" to update /boot/extlinux/extlinux.conf after changing file /boot/config.txt.
