SSH Login

Prerequisites

Developers need the following hardware and network environment:

• Mainboard: A8625 core board + debug baseboard
• Power: DC12V 3A power adapter
• Debug cable: USB Type-A to Type-C cable (for initial debugging)
• Network: A8625 and the host PC are in the same LAN (via adapter board RJ45 or same-subnet router)

SSH Software Installation

On Windows, cmd or PowerShell is recommended. On Linux/macOS, use the built-in ssh command.

Verify SSH client availability:

ssh -V

If the terminal outputs an OpenSSH version (for example OpenSSH_for_Windows_9.5p2), SSH client is available.

Boot the Board

• DC jack power (recommended): connect a 12V/3A adapter to J4 on the baseboard.
• Type-C power: if using 12V Type-C input, solder one 22.6K 0402 resistor at the corresponding board location (refer to adapter board hardware documentation), then connect to J10.
• After power-on, the system starts automatically.

Get Device IP

For first-time use, log in through ADB first and check current device IP:

adb shell ip a

Record the IP on the service NIC (for example 192.168.100.3), referred to as <A8625_IP> below.

Access the System via SSH

Run on the host terminal:

ssh aidlux@<A8625_IP>

At first login, confirm host fingerprint by entering yes and pressing Enter. Then input password aidlux.

Common SSH Commands

These commands are commonly used in remote operations and maintenance:

1. ssh aidlux@<A8625_IP>

Purpose: log in to device shell for remote debugging.

ssh aidlux@<A8625_IP>

2. Upload via scp

Purpose: upload host files to device, commonly scripts, models, or config files.

scp ./test.sh aidlux@<A8625_IP>:/tmp/test.sh

3. Download via scp

Purpose: download logs or result files from device.

scp aidlux@<A8625_IP>:/var/log/syslog ./syslog

4. ssh ... "command"

Purpose: execute a remote command once, suitable for automation scripts.

ssh aidlux@<A8625_IP> "uname -a"

Password

SSH username is aidlux, password is aidlux.

Recommendation

Run ping <A8625_IP> first to verify network reachability before SSH login and file transfer.

Use the System

After successful login, developers can configure the system, troubleshoot logs, and deploy applications through SSH.
