Walking Through Bootlin's Yocto STM32MP1 Lab
If you're new to embedded Linux, "Yocto Project" is one of those names that comes up constantly and sounds intimidating. This post is a friendly, beginner-focused walkthrough of Bootlin's free Lab 1 training, targeting an STM32MP1 development board, including every error I ran into along the way and what it actually meant.

This lab covers three areas: exploring the Linux device model through `/dev` and `/sys`, driving GPIOs through the sysfs interfaceAprEmbedded Linux · Part 4From Kernel Panic to Shell Prompt: Building a Minimal Linux Userspace on Raspberry Pi 4With TF-A, U-Boot, and the Linux kernel running on the Raspberry Pi 4, the boot chain is solid. But a kernel with no userspace is just a very expensive panic message.AprEmbedded Linux · Part 3Cross-Compiling the Linux Kernel for Raspberry Pi 4: From Source to BootWith TF-A and U-Boot running, we now control the full boot chain. The
next step is bringing up the Linux kernel itself — from source to first

Raspberry Pi 4, you know it is not as simple as flashing an image and
pressing power.AprI'm Building an AI Neonatal Monitor for the Hackster.io "Invent the Future with Arduino UNO Q and App Lab" contestAI Neonatal Monitor for the Hackster.io Arduino UNO Q ContestAprEmbedded Linux · Part 1How to Build an ARM Cross-Compiling Toolchain with Crosstool-NGBuilding embedded Linux systems means compiling code on your x86 laptop for an ARM64 board. Your native gcc can't do that — you need a cross-compiler. In this tutorial, you'll build one from scratch using Crosstool-NG: configure GCC 14.3.0 targeting AArch64, choose musl as your C library, and test your binary on QEMU without any physical hardware.MarMy Journey at Embedded World 2026If there's one event every embedded engineer should experience at least once, it's Embedded World. This year, I made the trip to Nuremberg for Embedded World 2026 (March 10–12), and I came back with a head full of ideas, a bag full of dev boards, and a clear sense of where our industry is heading...
