To customise test builds and support test related features such as time stamps and a boot banner, introduce a Makefile variant that is dedicated to testing. Initially we introduce a new config overlay that is used for all tests, in this case we enable BOOT_BANNER and BUILD_TIMESTAMP. This will print the current version and the date, useful when reporting bugs and also an indicator that the system has booted before the test has started. For example: [QEMU] CPU: qemu32 ***** BOOTING ZEPHYR OS v1.6.99 - BUILD: Dec 21 2016 19:57:13 ***** tc_start() - Test Nanokernel CPU and thread routines Initializing nanokernel objects ... ..

Title: Synchronization
Description:
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 Project:
This project outputs to the console. It can be built and executed
on QEMU as follows:
make qemu
--------------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
make clean # discard results of previous builds
# but keep existing configuration info
or
make pristine # discard results of previous builds
# and restore pre-defined configuration info
--------------------------------------------------------------------------------
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!
threadA: Hello World!
threadB: Hello World!
