Semiconductor Application Note

Multiple Target Features

Using CodeWarrior

John Winters

MOTOROLA

One of the benefits of the Software Development Kit (SDK)

for Motorola’s Digital Signal Processor (DSP) family of

processors is its flexibility. The SDK provides Stationery

(templates) to address External RAM and Flash. However,

templates to address new product hardware may be required

and can be developed using tools in CodeWarrior. This

document details the steps required to create a new build

target.

There are two meanings for the term “target”, as used by

CodeWarrior:

A build target is a particular collection of settings and files

that determines the content of your code and the process in

which the code is compiled and linked into the final output.

A platform target is the processor or operating system for

which you are writing code, represented as the choice of

linker specified in the build target settings panel.

In this document, the term “target” refers to a build target.

This application note details how to create the new Stationery

and build target for a prototype product configuration,

possibly differing in software, hardware, or both, from the

Flash and the External RAM build targets supplied with

standard SDK build Stationery. The new build target, proto,

is in addition to the existing build targets defined in the

Stationery.

These are the tasks required to add multiple varied build

targets:

1. The Stationery must be expanded
