Developed device-tree-based support for the COMFAST CF-XR186 WiFi repeater in the DragonBluep/openwrt repository, enabling OpenWrt operation on MT7981B hardware. The work involved creating a comprehensive device tree and configuring LED indicators to reflect network activity, with blue and green LEDs mapped to 2.4 GHz and 5 GHz radios and a red LED for status. Leveraging expertise in Linux kernel and device driver development using C, the implementation aligned with AX3000 platform requirements and supported a single Ethernet port. This addition facilitated reliable sysupgrade-based firmware replacement, improving maintainability and reducing vendor lock-in for future embedded platform deployments.
