Slay the Daemons on Embedded
4th October, 2026 15min
My name is Chris and I'm afraid of daemons. Well, not literally but I am engineering the firmware for an embedded, real-time device. And I chose to use Debian Linux with systemd. What I'm afraid of are background processes, daemons, performing actions I don't anticipate. This article explains how I create a linux image for my device with only a handful purposeful daemons.

Automatic Firmware Generation for Spaceflight Hardware based on Schematics
19th August, 2026 15min
The interaction between hardware design and firmware implementation requires strict consistency in embedded systems. Firmware must exactly match the schematic-level component configuration and connectivity. In current workflows, this consistency is largely ensured through manual inspection and extensive testing. In this work, we introduce a schematics-aware approach to automate firmware generation. We propose the Group Netlist, a design- and PCB tool-agnostic abstraction of hardware. Using a reference implementation, we demonstrate our proposal for the open-source PCB design suite KiCad. As added benefit our approach serves for hardware verification purposes that we demonstrate through a fault-injection analysis. Considering relevant cases, our tool detects 75% of otherwise undetected injected faults and requires negligible overhead (less than 0.2% codebase addition and on average a 4.8% runtime increase). Lastly, we verify our tooling by successfully using it in the development workflow of an embedded satellite module.
