RTEMS Development Environment Guide
The RTEMS source distribution includes a set of sample applications
that are located in the ${RTEMS_ROOT}/testsuites/samples/
directory. These applications are intended to illustrate the
basic format of RTEMS single and multiple processor
applications and the use of some features. In addition, these
relatively simple applications can be used to test locally
developed board support packages and device drivers as they
exercise a critical subset of RTEMS functionality that is often
broken in new BSPs.
Some of the following sample applications will be covered in more detail in subsequent sections:
${RTEMS_ROOT}/testsuites/samples/hello/.
This test is helpful when testing new RTEMS development environment.
${RTEMS_ROOT}/testsuites/samples/ticker/
subdirectory provides a test for verification of clock chip
device drivers of BSPs.
${RTEMS_ROOT}/testsuites/samples/base_sp/.
${RTEMS_ROOT}/testsuites/samples/base_mp/.
${RTEMS_ROOT}/testsuites/samples/capture/.
This is an interactive test which demonstrates the capabilities
of the RTEMS Capture Engine. It includes a few test threads
which generate interesting execution patterns. Look at the
file ${RTEMS_ROOT}/testsuites/samples/capture/capture.scn
for a sample session.
${RTEMS_ROOT}/testsuites/samples/cdtest/
subdirectory provides a simple C++ application using
constructors and destructors. It is only built when
C++ is enabled and its primary purpose is to demonstrate
that global constructors and destructors work. Since this
requires that the linker script for your BSP be correct, this is
an important test.
${RTEMS_ROOT}/testsuites/samples/fileio/.
This is an interactive test which allows the user to interact with
an ATA/IDE device. It will read the partition table and allow the
user to dynamically mount one of the FAT32 partitions it finds.
Commands are also provided to write and read files on the disk.
${RTEMS_ROOT}/testsuites/samples/iostream/.
This test is a simple C++ application which demonstrates that
C++ iostreams are functional. This requires that the RTEMS C++
run-time support is functioning properly. This test is only
build when C++ is enabled.
${RTEMS_ROOT}/testsuites/samples/loopback/
directory contains a sample test that demonstrates the use of
sockets and the loopback network device. It does not require
the presence of network hardware in order to run.
It is only built if RTEMS was configured with networking enabled.
${RTEMS_ROOT}/testsuites/samples/minimum/
contains a simple RTEMS program that results in a non-functional
executable. It is intended to show the size of a minimum footprint
application based upon the current RTEMS configuration.
${RTEMS_ROOT}/testsuites/samples/nsecs/.
This test demonstrates that the BSP has support for nanosecond
timestamp granularity. It prints the time of day and uptime multiple
times as quickly as possible. It should be possible from the output
to determine if your BSP has nanosecond accurate clock support
and it is functional.
${RTEMS_ROOT}/testsuites/samples/paranoia/
contains the public domain floating point and math library test.
${RTEMS_ROOT}/testsuites/samples/pppd/.
This test primarily serves as the baseline for a user application
using the PPP protocol.
${RTEMS_ROOT}/testsuites/samples/unlimited/
directory contains a sample test that demonstrates the use of the
unlimited object allocation configuration option to RTEMS.
The sample tests are written using the Classic API so the reader should be familiar with the terms used and material presented in the RTEMS Applications Users Guide.
