Lightfoot SDK Examples

The Lightfoot SDK contains a large number of examples that are designed to demonstrate the many capabilities of the SDK. This set of web pages describes each of the examples, what they are demonstrating, how to build them and how they use the specific feature.
Most of the examples are either built using the lfmake utility provided with the SDK. However some of the Java examples are built with ANT (http://ant.apache.org/) . A version of ANT is provided with the SDK distribution.
When the SDK is installed, the examples are prebuilt using the latest BSP for the VS2000 EVB. If you have a different BSP, you must rebuild the examples for your BSP using the following command.
lfmake -C %LF_HOME%\examples clean all

If you have ANT installed, you can also rebuild the ant examples

ant -f %LF_HOME%\examples clean all

Some of the examples demonstrate running in the software simulator. Before doing this, you may need to rebuild the example with debug enable. You can do this by the following commands

lfmake clean all DEBUG=1

or for the ANT examples

    ant clean build -Ddebug=yes

Some of the examples demonstrate running using the hardware debugger. Before doing this, you may need to ensure that the correct devices for ethernet are enabled in the config.xml file and then rebuild using the following commands.
    lfmake clean all DEBUG=1 DCT_BUILD_HW_DEBUG=1

or for the ANT examples

    ant clean build -Ddebug=yes -Ddebug.hw=yes

Networking

A number of these examples make us of networking. By default the boards will obtain the IP address from the monitor, allowing them to work using either a crossover cable or a larger network.

Record Store

Some of the examples could make use of a record store. The record store has not been enabled by default on these examples and throws an exception when starting up. In order to make use of the record store, rebuild the appropriate example adding the argument 'USE_RMS=1' to the command line.
