Introduction

The CY3663 EZ-Host and EZ-OTG Development Kit contains

a full set of standard GNU-based tools. These tools have

been ported to our CY16 processor-based EZ-Host and

EZ-OTG products. This application note describes how to

build a simple stand-alone project with these tools that will run

in either debug mode or out of an EEPROM. This document

is intended to help those less familiar with the GNU devel-

opment environment. It is not intended to be a complete tools

reference, but rather a quick example to get you familiar with

the tools.

The example in this document is presented from start to finish

and is all-inclusive. To make things easier to follow, this

example does not have any dependencies on ROM BIOS

code (except for initialization), Frameworks, Makefiles, or any

other presupplied code that the design examples in our

CY3663 development kit use. It is strongly recommended that

production designs do not start from scratch as this example

does. Instead, production designs should rely heavily on our

BIOS and Frameworks code. For more information on devel-

oping around the BIOS and Frameworks, please see the book

USB Multi-Role Device Design by Example included in the

CY3663 development kit.

Required Tools Components

Below is a list of tools that are required to build and run the

example in this application note (or any other project, for that

matter). All of the required tools listed below, including many

other tools, are installed automatically when the CY3663 CD

is installed. In fact, these tools have many environmental

dependencies in order to work properly that are also automat-

ically handled by the install, so please properly install the

CY3663 CD before attempting to build an EZ-Host or

EZ-OTG project. For complete documentation on all utilities

below, including standard RedHat GNUPro documentation,

please refer to the CY3663 documentation folder.

Buttons and Lights Example Description

To properly understand how to use these tools, it is best to

actually build a simple project. This application note uses the

ever-popular Buttons and Lights as that example. Buttons

and Lights is a very basic application so as to allow focus to

remain on the tools, but at the same time presents a visual

indication that the code is running. It should be noted that this

is not the same Buttons and Lights example presented in the

USB Multi-Role Device Design By Example book.

The Buttons and Lights example presented here can run on

either the EZ-Host or EZ-OTG stand-alone boards shipped

with the CY3663 development kit. When this code is running,

pressing the S5 button will turn ON LEDs D1, and D9:D7.

When button S1 is pressed, these LEDs will turn off.

The EZ-Host and EZ-OTG stand-alone boards indirectly

memory map these LEDs and buttons through the U8 CPLD.

Therefore, this example bit bangs a standard memory

interface to RD/WR the CPLD. A complete description of

these boards, including the CPLD indirect memory map, is

included in the CY3663 Hardware Users Manual included

with the CY3663 kit.

Steps for building the Buttons and Lights example are

covered in later sections of this application note.

Buttons and Lights Project Files

Below is a short list of the files that make up this Buttons and

Lights example.

BAL.c File Description

This file contains a simple main routine along with functions

to read and write the CPLD. The main routine is just a

“while(1)” loop that looks for button presses and illuminates

the LEDs as appropriate.

StartupNoBIOS.s/StartupWithBIOS.s File Description

The default GNU start-up code is generally contained within

crt0.s. The crt0.s file contains a lot of code overhead in

functions that are rarely used for embedded applications.

Therefore, we will supply our own start-up code in a.s file and

instruct the compiler to use it instead of the default crt0.s file.

This will save quite a bit of code space. For more information

on minimizing code space by not using crt0.s, please see the

OTG-Host Boot Code Design white paper included in the

CY3663 kit.
