Important Notes

Configuration Precautions

• It is recommended to use the mainsail or fluidd web interface for configuration changes.
• Do not enable webpage translation, as it may prevent the system from starting normally.
• Do not input Chinese characters or special symbols in configuration files.
• A system restart is required for configuration file changes to take effect.

Critical Warning

• Do not modify any content below the line ######### PLEASE DO NOT EDIT THE FOLLOWING ######### in the configuration file.

Configuration File Modification Methods

Modifying Configuration After Flashing

• For configuration items that only take effect on the first boot, you must modify the config.txt file located in the removable disk FlyOS-Conf using a professional text editor after the flashing process is complete.

Online Configuration Modification After System Boot

• Common configuration items can be modified on the system's web configuration page and will take effect after a restart.

1. Access the device's IP address via a browser, e.g., http://192.168.1.2/

fluidd Interface Operation: Uncheck "Filter hidden files and folders"

mainsail Interface Operation: Check "Show hidden files"

2. Navigate to the displayed .flyos-config folder and locate the sys-config.conf configuration file.

3. Edit the sys-config.conf file. This file is a symbolic link to the config.txt file in the removable disk FlyOS-Conf.

4. After modifying the configuration items, save the file and restart the system for the changes to take effect.

Configuration Format Note

• The configuration file must follow the format key=value. Do not change it to key: value or any other format.
• Do not add spaces before or after the equals sign.
