Synchronization Sample

Overview

A simple application that demonstrates basic sanity of the kernel. Two threads (A and B) take turns printing a greeting message to the console, and use sleep requests and semaphores to control the rate at which messages are generated. This demonstrates that kernel scheduling, communication, and timing are operating correctly.

Building and Running

This project outputs to the console. It can be built and executed on QEMU as follows:

Using west:

west build -t run

Using CMake and ninja:

cmake -B build -GNinja -DBOARD=qemu_x86 samples/synchronization
ninja -C build run
