Synchronization Sample

Overview

A simple application that demonstates 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:

$ cd samples/synchronization
$ make run

On the supported ARM MCUs the project can be built with the MPU and the Thread Stack Guard feature enabled:

$ cd samples/synchronization
$ make BOARD=v2m_beetle CONF_FILE=prj_stack_guard.conf

Sample Output

threadA: Hello World!
threadB: Hello World!
threadA: Hello World!
threadB: Hello World!
threadA: Hello World!
threadB: Hello World!
threadA: Hello World!
threadB: Hello World!
