PROFILE
Marco Von Rosenberg
Worked on hardware enablement and reliability improvements for Huawei access points in the DragonBluep/openwrt and coolsnowwolf/immortalwrt repositories, focusing on embedded Linux and device driver development. Delivered end-to-end OpenWrt support for the AP4050DN, including device-specific partitioning, bootloader configuration, and automated build integration using C, Makefile, and Shell. Addressed bootloader size constraints with a second-stage U-Boot workflow and enhanced deployment reproducibility. Fixed critical PHY initialization and initramfs boot issues for AP5030DN and AP6010DN by tuning kernel drivers and memory management, reducing field failures. Contributed comprehensive documentation and reproducible deployment steps to support maintainers and enterprise deployments.
