How to Actually Use AI Coding Agents — 6 Skill-Specific Tips

TL;DR The real problem with AI coding is not model quality but which stage you hand what to — a nonexistent CONFIG_SPI_NRFX_SPIM3 in Zephyr passing the build and then bricking boot is the proof. The

The Build Passed, So Why Doesn't It Run — Automating Firmware Tests on Real Hardware

TL;DR A passing west build doesn't mean the firmware runs on hardware — catching silent failures manually doesn't scale. Combining Zephyr Twister's --device-testing mode with a self-hosted runner gi

Embedded Firmware Development with Claude Code — Devicetree, Kconfig, and Debugging

TL;DR 75% of Zephyr firmware development time goes to Kconfig/devicetree configuration and build error interpretation, not writing code — Claude Code can intervene in that 75% directly from the termi

NCS Project Management Guide: Ditching Global Install to Reclaim Control

TL;DR Patching SDK internals in an NCS global install silently breaks every other project on your machine. Freestanding (manual ZEPHYR_BASE binding) → T2 (app owns west.yml manifest) → T3 (separate
