LED
5B LED
On the rock5, one LED is configured as LED class device.
You can control it via /sys/class/leds/
The default status of the three on board led is flash
root@rock-5b:/home/rock# echo none > /sys/class/leds/sta/trigger root@rock-5b:/home/rock# echo activity > /sys/class/leds/sta/trigger root@rock-5b:/home/rock# echo timer > /sys/class/leds/sta/trigger
You can use cat on the trigger property to list all the available values.
root@rock-5b:/home/rock# cat /sys/class/leds/sta/trigger none rfkill-any rfkill-none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock tcpm-source-psy-4-0022-online timer oneshot disk-activity disk-read disk-write ide-disk mtd nand-disk heartbeat backlight gpio cpu cpu0 cpu1 cpu2 cpu3 cpu4 cpu5 cpu6 cpu7 mmc0 mmc2 activity [default- on] transient flash torch panic netdev
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 2022-06-22 10:09:59.214788+08:00 root@rock-5b:/home/rock# date Wed Jun 22 10:17:01 CST 2022
Ethernet
5B Ethernet
ROCK 5B is equipped with one 2.5G Ethernet port. You can use a network cable (one end connected to the external network port or route) to connect your ROCK 5B to the network. The ROCK 5B will automatically configure the network for your surfing on the Internet.
Manually configure Ethernet
- 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 or enP4p65s0 , 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 or $ sudo dhclient enP4p65s0
Storage device
- microSD card: /dev/mmcblk0
- eMMC: /dev/mmcblk1
- NVME M.2 SDD: /dev/nvme0n1

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.
