During January 2026, Jun Cai Xingchi expanded hardware support in the DragonBluep/openwrt repository by enabling OpenWrt on the Z-ROUTER ZR-2662, a WiFi 6 router. He developed device-tree specifications, established default network configurations, and implemented a complete installation and recovery workflow, including tftp-based initramfs installation and NAND flash sysupgrade. His work focused on Linux kernel development and embedded systems, using C and Makefile to ensure seamless firmware integration. By aligning documentation and commits for upstream contribution, Jun addressed the need for broader hardware compatibility and streamlined provisioning, delivering a well-scoped feature that improves OpenWrt’s support for modern devices.
