How to Modify the Configuration File

Modifying the Configuration File After Flashing

• Configuration options that only take effect on the first boot must be modified by using a professional text editor to open the config.txt configuration file located in the FlyOS-Conf removable disk immediately after flashing.

Online Configuration Modification After System Startup

• For general configuration options, you can modify them via the web configuration interface of the system and the changes will take effect after restarting the system.

  • Open the device's IP address in your browser, for example: 192.168.1.2/
  • In fluidd, uncheck the option as shown in the left image below -> Hide hidden files and folders.
  • In mainsail, check the option as shown in the right image below -> Show hidden files.
  • You will now see the .flyos-config folder. Inside this folder there is a file named sys-config.conf.
  
  • The sys-config.conf file is a symbolic link to the config.txt configuration file located in the FlyOS-Conf removable disk.
  

  • Open the sys-config.conf file, modify the required configuration items, then Save -> Close and restart the system.

  • Note: The format of configuration items in the sys-config.conf file is key=value. Do not change it to key: value.

  • After saving modifications, restart the system for the changes to take effect.
