PROFILE

Andreas Böhler

Worked on expanding and stabilizing hardware support in the DragonBluep/openwrt and coolsnowwolf/immortalwrt repositories, focusing on embedded systems and Linux kernel development. Delivered device tree configurations and Makefile enhancements to enable firmware builds for devices such as the KuWFi N650 CPE and ZyXEL GS1920-24HPv1 switch, improving deployment flexibility and hardware compatibility. Addressed critical bugs by correcting WiFi device tree assignments and refining hardware control scripts for D-Link and XikeStor devices, ensuring reliable fan operation and accurate port LED behavior. Utilized C, Device Tree Source (DTS), and shell scripting to streamline build processes and enhance system stability.

March 2026 — DragonBluep/openwrt hardware-control reliability improvements for D-Link and XikeStor devices. Delivered targeted fixes to critical bring-up scripts, reducing field issues and accelerating production readiness. Key deliverables: - D-Link fan control script fix: corrected variable name to ensure the fan activates as intended (commit 41d6584d9bd7628fe836ef63904748892d632679). - XikeStor SKS8300-12E2T2X GPIO mappings fix: added TX Disable GPIOs for SFP modules and LED Sync GPIO mapping to ensure accurate port LED behavior (commit a3988cd65cac5c36e3ecfe5476debb3c0b97bbcd). Impact: - Improved hardware bring-up reliability and operational stability on these devices. - Reduced risk of misbehaving fans and incorrect port LEDs, leading to fewer field issues and faster deployments. Technologies/skills demonstrated: - OpenWrt/Realtek hardware bring-up, GPIO/LED control, SFP signaling, and script debugging. - Version control discipline with traceable commits. Business value: - Lower support load, smoother customer deployments, and faster time-to-value for new hardware configurations.

Oct 1, 2024

October 2024 monthly summary for coolsnowwolf/immortalwrt. Focused on stability and hardware compatibility. Delivered a targeted bug fix to restore WiFi on Sercomm NA502/NA502s by correcting the device tree: reassigning the WiFi chips from PCIe0 and PCIe1 to PCIe1 and PCIe2. This fix, committed as cbefc64cb33cc693fb551111021e95eb976b51bb, resolves degraded WiFi behavior and eliminates model-specific support gaps. No new features released this month; emphasis on root-cause analysis, regression prevention, and reliable user experience.
