1.5 The Freescale CodeWarrior Development Tool Chain
Freescale CodeWarrior is a cost-effective and highly functional
Integrated Development Environment (IDE) containing a complete
suite of development tools to create, compile, link, debug, and
assemble fast, optimized embedded systems code for the PowerPC
5xx/6xx/8xx and other architectures.
The Freescale CodeWarrior Integrated Development Environment
(IDE) is intuitive, easy to use and designed to provide a variety of
tools that work in a cohesive manner regardless of the host, language,
or target architecture. This means you can reach more markets and
solve more problems without having to learn new tools. Freescale
CodeWarrior IDE's graphical interface includes an editor, project
manager, class browser, compiler, source-level and assembly-level
debugger, stand-alone assembler, and linker.
In addition to keeping all your development tools a keystroke away,
the IDE stores compiler settings and tracks all the dependencies for
your project, simplifying even the most complex development build.
The editing and software debugging tools in CodeWarrior are state-of-
the art and feature syntax highlighting, the power to evaluate
structures and complex expressions in the debugger, and the ability to
correct source code in the error message window.

phyCORE-MPC555 QuickStart Instructions
Freescale CodeWarrior consists of the IDE and Debugger core tools,
which are structured as follows:
IDE:
Windows-based Integrated Development Environment housing the
following tools:
•Project Manager: shows the collection of files used to build an
output file
•Editor: double-clicking on a file in the Project
Manager window invokes the Editor
•Build System: IDE plug-in “tools” to create and then convert
source code to output code
•C compiler: IDE plug-in
•Linker: IDE plug-in
•Make: IDE plug-in
•Debugger: Fully active source-level and assembly-level
Windows-based debugger
Upon installation of CodeWarrior, the IDE and Debugger executables
are located in the C:\Program Files\Freescale\CodeWarrior EPPC
5xx V8.7\Bin folder. All tool commands are easily accessible via
intuitive pull-down menus with prompted selections.
As depicted below, CodeWarrior’s editor, C/C++ compiler, linker and
debugger comprise the basic tool chain. The remaining plug-in tool
components assist in code navigation and build control.
Figure 1: Freescale CodeWarrior IDE Architecture

Introduction to the phyCORE-MPC555
© PHYTEC Messtechnik GmbH 2009 L-524e_5 9
All IDE commands and functions are accessible via pull-down menus
or short cuts. An extensive Help utility is included.
The Project Manager gathers all necessary source files, library and
project information - such as various output files (called targets) with
different memory maps for RAM-download or ROM-imaging - and
stores it in a project file assigned the suffix *.mcp. From the project
manager window, all other tool components are easily accessible via
mouse control.
The Editor is a powerful tool to compose source code. It includes a
context-sensitive coloring of keywords for easy navigation and recog-
nition. All colors and custom keyword sets can be user-defined. Pop-
up menus provide an overview of all available functions and a navi-
gation to the start of a desired function or its corresponding header
file. A graphic difference engine displays the differences between two
source code files. The search engine enables location of a specified
text string and implements find-and-replace operations.
The Build System contains the C/C++ compiler, assembler, linker and
code converter. The CodeWarrior compiler produces fast, optimized
embedded systems code. The C compiler is NIST Certified ANSI C,
and the C++ compiler closely tracks the emerging ANSI/ISO C++
standard. To increase the compilation speed the compiler can generate
precompiled headers. For syntax check, the compiler provides pre-
processing of single source files or for the complete project. For code
exploration, a disassembly command displays the corresponding
assembler code that the C code compiles to.
The compiler and linker support *.elf and Freescale S-record output
file formats. A map file is also generated, providing detailed memory
map and module information.

phyCORE-MPC555 QuickStart Instructions

The CodeWarrior Debugger provides C/C++ source-level, as-
sembly-level and mixed mode debugging. For code exploration, ab-
solute or conditional breakpoints can be accessed or single-step
operation can be performed. Step-over, step-into and step-out of code
function capabilities are provided. The contents of variables, arrays
and structures can be monitored and manually modified.
The Freescale CodeWarrior Debugger supports the following debug
options of the phyCORE-MPC555 target.
•A hardware-level debugging option is provided via a PC-to-target
connection using the MPC555 BDM-port (Background Debug
Mode), a hardware debugger module integrated on the processor.
The parallel printer port of the host-PC communicates to the
phyCORE via a BDM interface, such as the Macraigor Wiggler or
the BDM signal conversion logic integrated on the PHYTEC
Development Board. Furthermore for extensive software
development, more sophisticated BDM interfaces are available for
increase download speed.
•A connection via RS-232 to a software debug Monitor kernel
(MetroTRK, SDS Monitor) resident in the external or internal
Flash on the phyCORE. The phyCORE-MPC555 is delivered
without the MetroTRK monitor kernel resident in the Flash. It can
be programmed via BDM connection to the desired Flash memory.

2.2 Interfacing the phyCORE-MPC555 to a Host-PC
Connecting the phyCORE-MPC555 (part # PCM-001-xxxx, mounted
on the PHYTEC Development Board (part # PCM-995), to your
computer is simple:
•If the phyCORE module is not already connected, mount it onto
the Development Board's Molex connector (X1) as shown in the
figure below. Ensure that pin 1 of module matches pin 1 of the
receptacle on the Development Board.
Ensure that there is a solid connection between the module's pins and
the Development Board receptacle. If the phyCORE module is
removed from the Development Board, take precautions to properly
mount the module when it is reattached to the Development Board.
Pin 1 on the phyCORE module (denoted by the hash stencil mark on
the PCB) should be matched to the footprint receptacle on the
Development Board marked by "X1" on the PCB. Also take
precautions not to damage the connectors when the phyCORE is
removed from and inserted onto the Development Board.
