A.4 Frequently Asked Questions
Q1: What is the first step, after viewing the printed material from the box?
A1: Make sure the hardware works well enough to run the tutorial. After software installation, plug in
a development board; go through the DVK tutorial. The tutorial is located in the EZ-USB DVK User
Guide, which is found in the Start menu under Cypress > USB > Help. The tutorial is short and
worthwhile.
Q2: What is the first example to try?
A2: While following the tutorial, you will read the Device ID from the development board, and then
load the dev_io example. This turns on the LED so you know that firmware has been loaded and
runs correctly.
Q3: Where do I find the soft copy of the EZ-USB Getting Started?
A3: See <Installed_directory>\<Version>\Documentation\EZ-USB (R) DEVELOP-
MENT KIT USER GUIDE.pdf.
Q4: Where do I find the soft copy of the EZ-USB Technical Reference Manual (TRM)?
A4: See <Installed_directory>\<Version>\Documentation\EZ-USB(R) Technical
Reference Manual.pdf. This is the key reference to use. You can search for the material you are
most interested in quickly.
