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
