Chapter 1 Product Overview

1.1 Introduction

BeagleBone-HDMI Cape (hereafter refers to BeagleBone-HDMI) is an extension board

designed by Embest Technology for extending the functions of the BeagleBone

development board that was built on TI’s Sitara AM335x microprocessors.

BeagleBone-HDMI is capable of providing HDMI output including both audio and video

signals with a video resolution of up to 720p. Additionally, it has a 50-pin LCD interface

for the connection of a 4.3- or 7-inch LCD display. The LCD and the HDMI interfaces are

working under multiplexing mode, which means only one of the interfaces could function

at a time.

Chapter 3 Preparation before Use

To demonstrate the BeagleBone-HDMI, users may directly use the Linux and WinCE

operating systems contained in the CD-ROM attached in the package. Before we can do

so, we need to make some preparations including installation of USB driver and setting

up HyperTerminal in Windows.

3.1 Installation of USB Driver

1） Copy the folder usb driver under linux/tools/ of the CD-ROM to the hard

drive of your PC;

2） Use a USB cable to connect the miniUSB interface on Beaglebone to the

USB interface on PC;

3） Select Yes, this time only in pop-up window and click Next, as shown

below;
