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/ 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/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

Here is the example of upgrading rockchip-overlay and kernel packages.

$ sudo apt-get update
$ sudo apt-get install -y rockchip-overlay

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.

Ethernet throughput test result table.

Direction Bitrate
Upstream 2.34 Gbits/sec
Downstream 2.35 Gbits/sec
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 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

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