Radxa Board Information

• Devide Model:
• Serial Number:

radxa-config

The Kernel Command Line

The Linux Kernel accepts a command line of parameters during boot. Radxa official Ubuntu/Debian provide one file uEnv.txt in the boot partition to for user to add the needed kernel parameters. uEnv.txt is a simple text file that can be edited using any text editor, e.g. nano, vim, etc.

We need to add all the parameters to the line

extraargs=

Command Line Options

max_loop: set the number of loop device

extraargs=max_loop=8

mem: set memory

extraargs=mem=512MB max_loop=8

Configuring Networking

netplan.io: Network configuration in YAML

Here is one example for setting Ethernet and WiFi static IP address on ROCK Pi S.

Setting Ethernet Static IP Address

Install package netplan.io

root@rockpis:~# apt-get install -y netplan.io

Create file, /etc/netplan/01-ethernet.yaml. If there is no /etc/netplan folder, create it.

root@rockpis:~# touch /etc/netplan/01-ethernet.yaml

Add the following contents to the file, /etc/netplan/01-ethernet.yaml and save it.

root@rockpis:~# cat /etc/netplan/01-ethernet.yaml 
network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
        - 192.168.1.200/24
      gateway4: 192.168.1.1
      nameservers:
        addresses:
          - "192.168.1.1"
          - "8.8.8.8"

Run the commands below to apply our changes.

root@rockpis:~# netplan apply

To validate that our changes are applied, run the commands below to view the IP address configuration detals.

root@rockpis:~# ip addr show dev eth0

It should display similar lines like the one below:

root@rockpis:~# ip addr show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
    link/ether c2:68:e0:7c:9b:09 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.200/24 brd 192.168.1.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::c068:e0ff:fe7c:9b09/64 scope link 
       valid_lft forever preferred_lft forever

Setting Wi-Fi Static IP Address

root@rockpis:~# cat /etc/netplan/02-wireless.yaml 
network:
  version: 2
  renderer: networkd
  wifis:
    wlan0:
      dhcp4: no
      dhcp6: no
      addresses: [192.168.1.220/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [192.168.1.1, 8.8.8.8]
      access-points:
        "rockpi-2.4g":
          password: "rockpistar"

Run the commands below to apply the changes.

root@rockpis:~# netplan apply

Validate that our changes are applied.

root@rockpis:~# ip addr show dev wlan0
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 4a:33:14:54:4a:03 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.220/24 brd 192.168.1.255 scope global wlan0
       valid_lft forever preferred_lft forever
