TECHNICAL SCOPE
The distribution is chosen around supported hardware, update lifecycle and maintenance. Yocto, Buildroot and OpenWrt address different needs: the goal is a reproducible configuration with known components and a clear device installation and recovery process.
Before changes, I clarify the available BSP, hardware variants, update responsibilities and existing release procedures. I can contribute to an existing image, a service or a specific integration without requiring a replacement distribution or infrastructure.
A release can be checked by rebuilding the image from documented inputs, booting the device and checking services, interfaces and recovery from agreed faults. Build reproducibility, boot and update behaviour are separate checks with explicit configurations and results.
Build configurations and recipes, agreed images, package inventory and operating instructions. Tests document boot, connectivity, services and recovery from defined failure conditions.
Specify the board and SoC, required interfaces, connectivity, available storage and expected product support lifecycle.
They are examples of build systems. The solution follows the platform, existing distribution, support lifecycle and client operating practices.
SLX Router is a professional Debian router for SMBs, MSPs, CCTV and IoT/OT networks: business firewall, WireGuard VPN, VLANs, NAT, QoS, backup, web dashboard, network security, PDF reports and controlled maintenance.
From kWp and AC power balances to battery reserve and EV charging: a technical exploration of photovoltaics, energy calculations, EEBUS, SunSpec and the SolarPilot Linux/LVGL controller.
eBPF makes the Linux kernel observable and programmable in a controlled way. On embedded systems, it can help diagnose issues, monitor traffic, strengthen security and reduce debugging time on deployed devices.
How to reduce embedded Linux boot time by measuring and optimizing bootloader, kernel, drivers, filesystem and init system.
Why OpenWrt can be more than router firmware: networking, security, automation and reproducible Linux builds for gateways and edge devices.
