Remote Login

This section aims to introduce how to log in remotely via serial port or network (VNC, SSH) to users who need to access the development board remotely via a personal computer (PC).

Before logging in remotely via the network, the development board needs to be connected to the network via wired Ethernet or wireless WiFi, and the IP address of the development board needs to be configured. For the IP address information under the two connection methods, please refer to the following description:

• Wired Ethernet: The development board uses static IP mode by default, with an IP address of 192.168.127.10, mask 255.255.255.0, and gateway 192.168.127.1
• Wireless WiFi: The IP address of the development board is generally assigned by the router. The IP address of the wlan0 network can be viewed through the ifconfig command in the device command line

SSH login

In addition to logging in to the remote desktop via VNC, you can also log in to the development board through SSH connection. The following are the steps to create two methods: terminal software and terminal command line.

Terminal software

Currently, commonly used terminal tools include Putty, MobaXterm, etc. Users can choose according to their own usage habits. The port configuration process of different tools is basically similar. The following takes MobaXterm as an example to introduce the process of creating a new SSH connection:

2. Enter the IP address of the development board, for example, 192.168.127.10
3. Select specify username and enter sunrise
