Xiao nRF54L15 Development Guide: VSCode + nRF Connect SDK

Excellent Forum Solutions XIAO

I’ve created two markdown development guides for the Xiao nRF54L15, optimized for use with GitHub Copilot and other AI coding assistants in VSCode with the nRF Connect extension.

Two versions for different use cases:

  • Full Guide (nrf54l15-guide-full.md): Human-readable with detailed explanations, examples, and context. Best for learning and reference.

  • Compressed Guide (nrf54l15-guide-compressed.md): ~65% smaller, AI-optimized for context window efficiency. Contains all essential information in a token-efficient format.

Both guides cover:

  • Complete build/flash/debug workflows

  • Environment setup (temporary & permanent)

  • Multi-core development (ARM Cortex-M33 + RISC-V FLPR)

  • Device tree aliases and peripheral access

  • Recovery procedures for bricked boards

  • GDB debugging commands

  • Project structure requirements

Key features:

  • Enables fully automatic build/flash/recovery inside VSCode with nRF Connect

  • Includes links to Xiao-specific sample code repository

  • PowerShell commands tested on Windows

  • Works with nRF Connect SDK v2.7.0+ (v3.2.0-preview2+ recommended)

Use the compressed version when working with AI assistants that have limited context windows, or switch to the full guide when you need more detailed explanations.

Hi there,

WOW

We know how the nRF54 series is brand-new, multi-core, and full of quirks :face_with_open_eyes_and_hand_over_mouth: (FLPR, P2 domain, recovery procedures, west commands, overlay rules, boot flows, etc.)?
Most beginners drown in that stuff.
Even intermediate devs waste hours searching through random Nordic docs.

This guide packs everything required to build/flash/debug without guesswork into one file.

In plain terms, use this so you don’t:

  • forget the right west commands

  • break the project structure

  • misconfigure VSCode’s nRF Connect extension

  • brick the board without knowing how to revive it

  • fight device tree paths

  • confuse which core runs what

  • lose time to AI assistants that hallucinate wrong build setup

It’s a productivity booster and an error killer, a must read & review.

Really cool @Toastee0

Bonus :grin: You can simply link to the relevant section. :+1:
