During January 2025, work focused on expanding hardware support in the coolsnowwolf/immortalwrt repository by implementing Huasifei WH3000 router compatibility based on the MT7981A platform. This involved creating detailed device tree configurations, defining board-specific LED and network interface settings, and establishing image generation rules to ensure seamless integration with the OpenWrt build system. Using C and Shell, the developer applied expertise in embedded systems and Linux kernel development to enable end-to-end recognition and configuration for the new device. The contribution improved hardware coverage and streamlined the installation process for users, with all efforts centered on robust feature delivery and integration.
