1. Preparation
- Luckfox Omni3576 development board
- USB Type-A to Type-C data cable
- USB wireless/wired mouse/keyboard
- 100M/1000M Ethernet cable and router
- Monitor/TV with HDMI interface and HDMI cable
- 5V/3A Type-C power adapter (Omni3576 must use this adapter to power on to avoid insufficient power supply)
- USB to TTL module
Note: The default baud rate for Omni3576 is 1,500,000. Some USB-to-serial chips cannot reach this rate, and different chip series may vary. Verify compatibility before purchase. Recommended modules: CH343, FT232, CP2102. Avoid PL2303 and CH340.
2. Local Login
- Hardware connection: Plug the USB keyboard and mouse into the Omni3576 baseboard’s USB ports.
- Power on Omni3576: Connect the monitor and power adapter to the baseboard. (Wait patiently for the desktop to load completely on first boot. Do not disconnect power during this process.)
- Open terminal: Click the terminal icon at the bottom-left of the desktop.
3. ADB Login
3.1 ADB Installation
- Download the ADB installation package, extract it, and use it directly (click here to download).
- Right-click This PC and select Properties -> Advanced system settings -> Environment Variables.

- In System variables, edit
Pathand add the extracted ADB directory.

- Click OK to save the environment variables.

3.2 ADB Login
- Press Win + R, enter
CMD, and open the Windows terminal. Run an ADB command to confirm that ADB is available.

- If only one device is connected, run the following command in PowerShell or CMD:
adb shell
- If multiple devices are connected, view the list of currently connected ADB devices:
adb devices
Example:
C:\Users\cjw> adb devices
List of devices attached
103ea97dececc831 device
d48936ed7d1551fc device
- After confirming the target device, log in to the board by specifying the device serial number:
adb -s d48936ed7d1551fc shell
After plugging or unplugging the board, run adb devices again to confirm whether the target device has been recognized. If it is not recognized, try replacing the Type-C data cable and check whether the connector has poor contact.
4. Serial Port Login
1.1. Connect one end of the serial module to your computer and the other end to the TX, GND, and RX pins on the Omni3576 baseboard. Refer to the wiring diagram below:

- Open Device Manager on the computer, locate the corresponding COM port, and record it.

- Download MobaXterm and extract it.
- Open MobaXterm, select Session → Serial, and set the baud rate to 1,500,000 (1.5Mbps).

- Click OK, press Enter, and enter the username and password to log in.

5. SSH Login

5.1 Obtain Omni3576’s IP Address
If the computer and board are on the same LAN, SSH connection is straightforward. Ensure SSH is enabled (default) and no firewall blocks the connection. Use one of these methods:
-
Connect the board to the LAN via wired/wireless and check the router’s device list.
-
Use a LAN IP scanner like Advanced IP Scanner:
i. Run Advanced IP Scanner and click the "Scan" button to scan the IP addresses within the current local area network.
ii. ecord the current IP addresses.
iii. Power on the device and make sure it is connected to the network.
iv. Click the "Scan" button again to scan the IP addresses within the current local area network:
v. Exclude all the previously recorded IP addresses, and the remaining one will be the IP address of your Omni3576.
-
Log in to the development board via ADB or serial port, and use the
ifconfigcommand to check the IP address.
5.2 Log in using MobaXterm
- Download the MobaXterm remote login software. You can use it after decompressing.
- Open the MobaXterm remote login software, select "Session" -> "SSH", and enter the IP address (e.g., 192.168.10.128, fill in according to your actual IP) that we queried earlier in the "Remote host" field.

- After filling in, click "OK", and enter the login name and password for Omni3576: luckfox. (It's normal that there's no change on the screen when you're entering the password. Press the Enter key to access after finishing entering the password.)

- At this point, you have successfully logged in to Omni3576.
