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

A deep-dive into architectural failures, race conditions, timing drift, and buffer inconsistencies — and how we corrected them. Problem When we began integrating the PCM1862 across our modular SoM platforms, the expectation was straightforward: configure clocks, bring up I²S, wire DMA, and start capturing clean audio frames. Instead, we ran

Content-Security-Policy (CSP) is often treated as a box to check: paste a template from OWASP, sprinkle a few nonces, and call it secure. But in modern application stacks especially those built on the Next.js App Router, React Server Components, and real-time GraphQL connections a static CSP is not just

Designing LED status indicators seems simple pick some colors, map them to states, and call it a day. But anyone who has deployed IoT devices in real homes, clinics, or outdoor environments knows that LED semantics can become a source of confusion, support tickets, and misdiagnosis if not engineered with

Refine SSR in App Router Building predictable, low-latency SSR pipelines with Refine.dev and the Next.js App Router Server-Side Rendering (SSR) in Next.js App Router is powerful—and deceptively easy to misuse. A misplaced await, an auth check in the wrong component, or scattered data fetching can silently

While we were building internal engineering tools at Hoomanely for visualizing telemetry from our IoT devices. Trackers capture motion and position data. EverBowls measure weight and behavior signals. EverHubs aggregate sensor data at the edge before cloud upload. All of this flows through GraphQL APIs into dashboards built on Next.
