System Login |

This chapter uses MobaXterm as an example to show how to log in to the ShiMetaPi-Pico-G1 board via serial port and SSH, and enter the Linux command-line terminal for development and debugging.

1. Installing MobaXterm

Install the free version of MobaXterm from its official site, MobaXterm official site, as shown below: MobaXterm installation

Serial login is the most basic and reliable login method. It does not depend on network configuration and is suitable for first-time use and system debugging. The Pico-G1 board connects to the PC's USB port through a serial adapter board (FT232) and communicates using serial terminal software.

2.2 Hardware Connections

Required items:

Item	Description
ShiMetaPi-Pico-G1 development board	Target board
FT232 serial adapter board	Provided with the SDK
USB data cable	Connects the serial adapter to the PC
3 Dupont wires	Connect the serial adapter to the development board

Wiring:

Serial adapter	ShiMetaPi-Pico-G1 development board
TX	RX
RX	TX
GND	GND

Note

Connect TX to RX and RX to TX; do not connect same-name pins. GND must be connected, otherwise communication will be unstable. Do NOT connect the VCC pin — a voltage mismatch could damage the board.

2.3 Operation Steps

Step 1: Install the serial driver.

Install the FT232 driver on the Windows workstation. The driver is in the SDK release package at:

sdk/tools/windows/burning-tools/ftdi-driver/FTDI-CDM-Driver.exe

Double-click the installer and follow the wizard to complete installation.

Step 2: Confirm the serial port number.

Connect the serial adapter to the PC via USB, open Windows Device Manager, and check the port number under "Ports (COM & LPT)":

Device Manager
└── Ports (COM & LPT)
    └── USB Serial Port (COM3)    ← Note this port number

Expected output:

Port number examples: COM3, COM5, etc., depending on the PC

Step 3: Log in with MobaXterm

Note

The baud rate must be set to 115200.

Step 4: Reset

Connect and reset the board; the serial terminal prints boot information:

Tip

Press Enter during boot to enter the U-Boot command line; type boot to continue booting the Linux system.

3. Logging in via SSH

Note

SSH login is a network-based remote login method. The Pico-G1 board connects to the LAN via an Ethernet cable, and the PC uses SSH client software (such as MobaXterm) to connect to the board for remote command-line operation. The precondition for SSH login is therefore that the Pico-G1 board and the PC are on the same LAN.

Step 1: Download and install the LAN IP scanning tool Zenmap Zenmap Follow the prompts and click Next through the installation.

Step 2: Find the IP address of the Pico-G1 board

Open Zenmap.
Run Zenmap, select your network segment from the Target drop-down, select Ping scan for Profile, and click Scan to scan all IP addresses in the current LAN.
Record all currently scanned IP addresses.
Power on the device and ensure it is connected to the network (wait about 10 seconds after power-on is recommended).
Click the Scan button again to scan all IP addresses in the current LAN.
Exclude all previously recorded IP addresses; the remaining one is the Pico-G1's IP address.
