Compilation

Move to the $TwlSDK/build/demos.TWL/dsp directory and enter the following:

% make

 Compiling will begin, and the SRL executable file and the TEF files having the binary information will be generated in:

$TwlSDK/build/demos.TWL/dsp/(sample_name)/bin/(platform)/(target)/

   For example:

$TwlSDK/build/demos.TWL/dsp/simple-1/bin/ARM9-TS/Release/main.srl

will be the executable file for the simple-1 demo.
