Overview
What this challenge is about.
Write a Linux kernel module for an SPI sensor, expose temperature via sysfs, and deliver test code. Earn a verifiable certificate.
The scenario
The renewable-energy startup (around EUR 8M ARR, smart-grid devices deployed across Nordic utilities) has 6 firmware engineers, none of whom have written a kernel module — they need an external port to bootstrap the codebase + the team.
The Brief
What you'll do, and what you'll demonstrate.
Write a Linux kernel driver for a custom SPI sensor board that exposes a clean hwmon interface and ships with a userland test program.
Earning criteria — what you'll demonstrate
- Write a real Linux kernel module against the 6.x kernel API
- Use sysfs and devicetree to expose hardware to userland cleanly
- Handle SPI bus quirks (chip-select timing, byte ordering, calibration blocks)
- Bridge kernel + userland in C with a defensible test program
