PROFILE

Roland Reinl

Developed and integrated hardware support for multiple consumer routers across the OpenWrt and ImmortalWrt ecosystems, focusing on device-tree configuration, U-Boot adaptation, and robust firmware deployment workflows. Delivered end-to-end bring-up for models such as the Linksys MR6350 and MR9000 in the namiltd/openwrt repository, as well as D-Link and Cudy devices in coolsnowwolf/immortalwrt, ensuring reliable network initialization, MAC address management, and migration procedures. Leveraged C, Device Tree, and Shell scripting to streamline onboarding, reduce code duplication, and improve maintainability. Addressed device-specific bugs and optimized DTS handling, enabling scalable support and consistent deployment across evolving embedded Linux platforms.

Dec 1, 2024

December 2024 — ImmortalWRT (coolsnowwolf/immortalwrt). Delivered hardware support and reliability improvements for D-Link devices. Key features delivered: D-Link AQUILA PRO AI M60 router support on MT7986a including network interface setup, button controls, LEDs, flashing procedures, and primary MAC handling; stabilized network initialization to support porting to Gluon. Major bugs fixed: U-Boot variable handling for D-Link M30 A1 by removing bootpart logic from the bootcount script and ensuring sw_tryactive is set prior to flashing to prevent firmware boot from the wrong partition. Impact: expanded device coverage, improved reliability and deployment readiness for new hardware, reduced risk of mis-flashes, smoother Gluon porting. Technologies/skills demonstrated: MTK/filogic integration, U-Boot variable handling, MAC address management, flashing workflows, and device initialization testing.
