Sample Demo of the Compression/Decompression Library (CX)

Location

$REVOLUTION_SDK_ROOT/build/demos/cxdemo

Compilation

Change directory to $REVOLUTION_SDK_ROOT/build/demos/cxdemo and enter make. An executable (.elf) file will be generated in $REVOLUTION_SDK_ROOT/RVL/bin/demos/cxdemo/.

Execution

You must configure DVDRoot before execution. Be sure to specify the folder name $REVOLUTION_SDK_ROOT/dvddata as the DvdRoot argument of the SetNdEnv command.

Change to the $REVOLUTION_SDK_ROOT/RVL/bin/demos/cxdemo directory and do the following:

To simply execute a program, run the ndrun script using the .elf file as the argument.
To debug using CodeWarrior, do one of the following:

?Run $CWFOLDER/bin/IDE.exe with the .elf file as an argument.
?Launch $CWFOLDER/bin/IDE.exe, then drag the .elf file.
If the .elf file is associated with $CWFOLDER/bin/IDE.exe, double-click the .elf file.
