Introduction When designing mission-critical edge devices, engineers often face a familiar trade-off. On one side is Linux—powerful, flexible, and rich with ecosystems for networking, AI, and analytics. On the other is the deterministic world of bare-metal or RTOS-based microcontrollers, trusted for precise timing and reliability. In a recent edge-AI

The convergence of Artificial Intelligence and Internet of Things (AIoT) represents one of the most significant technological shifts happening right now. Unlike traditional IoT systems that simply collect and transmit data, AIoT devices think, learn, and make decisions at the edge—transforming raw sensor data into intelligent insights without depending

Most performance problems we’ve encountered in embedded systems didn’t come from weak hardware or poor algorithms. They came from decisions that felt harmless at the time extra logs during bring-up, convenient abstractions, background helpers added “just for safety.” None of these broke the system immediately. Instead, they slowly

Introduction Ever wondered what happens in those crucial milliseconds between powering on your smart device and seeing it spring to life? The journey from a cold hardware reset to a running application is one of the most fundamental processes in embedded systems—yet it remains invisible to most users. Unlike

Choosing a filesystem in embedded firmware looks simple — until real devices start writing logs, staging firmware updates, caching sensor data, or recovering from unexpected resets. What starts as a neat API turns into challenges involving corruption, wear, mount-time failures, memory stalls, directory explosions, and behavior that rarely shows up in
Firmware
Linker scripts are often treated as arcane build artifacts copied from reference projects, tweaked cautiously, and rarely revisited. That approach works until it doesn’t. As modern MCUs introduce fragmented memory regions, tightly coupled RAM, external flash, and DMA-sensitive buffers, vague linker assumptions quietly turn into runtime failures. This article

When DMA problems appear, they rarely announce themselves with a big red flag. More often, they show up as vague instability: a frame that arrives corrupted once every few thousand cycles, a sensor payload that occasionally looks stale, or a buffer that behaves differently at low throughput vs sustained load.

If you’ve ever shipped a long-running embedded product that relies on stable weight readings, you’ve likely learned a painful truth: load-cell systems rarely fail in the analog domain first they fail in firmware. Not because firmware is the root cause, but because firmware is the first place the

If there’s one thing every embedded engineer learns the hard way, it’s this: logging is both a diagnostic superpower and a silent system-killer. Too much verbosity buries the actual signal. Too little structure makes triage impossible. And remote-capture methods—if naïvely designed can distort the very timing bugs
Firmware
Yocto gives embedded teams extraordinary power but it also gives them extraordinary power to break their own systems in subtle, silent ways. Anyone who has shipped a commercial Linux-based device knows this: your build system becomes part of your product’s architecture. If the layering model is unstable, everything above
