FLSUN Speederpad USB Ethernet connection

For all who dont want to solder the RJ45 port to the PCB here is a work-a-round.

Requirements

• USB-Ethernet Adapter (actually it only supports RTL8152 chipsets because RTL8153 drivers are not available in the kernel by default)
• SSH access to Speederpad
• ✨Magic ✨

RTL8153 Chipsets

If your Adapter has an RTL8153 chipset you will need to add the drivers to the kernel. Thanks to attilabody for adding this missing drivers: https://github.com/attilabody/speederpad-kernel/releases/tag/v0.0.0-modules

After that you can try again with the following steps.

Configuration

Step 1

Connect to the Speederpad via SSH Client

Step 2

Put the LAN cable in the adapter and router and connect it via USB to the Speederpad

Step 3

On your SSH client type the followinng command:

ip link

now you should see the following output:

Copy the device name (red border) to a editor (e.g. Notepad)

Step 4

Now we must configure the interface. The following command will open the configuration file:

sudo nano /etc/netplan/01-network-manager-all.yaml

the config should looks like this:

Step 5

There are two options for configuration

Static

Replace enx00e04c013511 with the interface name from Step 3 and change the IP-Address and Gateway

network:
        version: 2
        ethernets:
                enx00e04c013511:
                        dhcp4: no
                        optional: true
                        dhcp6: no
                        addresses: [192.168.1.123/24] # Speederpad IP
                        gateway4: 192.168.1.1 # Your Gateway IP 
                        nameservers:
                         addresses: [8.8.8.8,1.1.1.1]

DHCP

Replace enx00e04c013511 with the interface name from Step 3

network:
        version: 2
        ethernets:
                enx00e04c013511:
                        dhcp4: yes
                        optional: true
                        dhcp6: no
                        nameservers:
                         addresses: [8.8.8.8,1.1.1.1]

Save the file (Command + X // STRG + X )

Step 6

Apply the config with the following command:

sudo netplan apply

Step 7

Reboot the Speederpad over the touchpanel. Go to Configuration -> System -> System Restart

After the reboot the Speederpad is connected over the USB-Ethernet adapter 🎉
