Installation and Setup of Development Board Software
3.1 Installation, Setup, and Running First Application
It is important to install the CDB47xxx Board software before connecting the USB cable
from the PC to the USB port of the CDB47xxx Board. Failure to install the evaluation
software before the initial connection can result in an inability to communicate with the
CDB47xxx.
3.1.1 Evaluation Software Installation
The DSP evaluation software installation will first install the Cirrus Logic

DSP evaluation software
followed by the USB drivers required to communicate with the CDB47xxx board.
1. Run the latest DSP evaluation software installation executable (cirrus_dsp_eval_.exe or
cirrus_dsp_sdk_.exe). This executable is supplied by your Cirrus Logic representative.
2. At the Welcome screen, click Next.
3. At the Cirrus Logic Licensing Agreement window, select the “I accept the agreement” radio button to
agree to the terms and then select Next.
4. Select the default destination directory suggested by the installer for downloading the evaluation kit
files.
5. Select the default directory suggested by the Installer for storing the shortcuts to the programs and
files you are downloading.
6. Press the Install button to begin the installation process.
7. Press the Finish button to complete the installation process.
3.1.2 Setting up the CDB47xxx Board with a DVD Player
Follow these steps to set up the CDB47xxx Board
1. Place the CDB47xxx and the CDB47XXX-DCxx daughtercard on a static-free surface.
2. If the boards are not connected, connect them together as shown in Figure 3-1 .
3. Connect the power supply jack to the CDB47xxx Board at J2 and the adapter to a wall power socket
or to a power strip.
Note: Never connect the power supply without the daughtercard being connected to the main board.
The switching regulators on the main board rely on voltage sensing paths provided by the
daughtercard. Opening these paths will cause the regulator ouput to reach potentially damaging
voltages.
4. Ensure that the D14 (blue), D7 (green), D8 (yellow), and D9 (red) power indicator LEDs on the
CDB47xxx illuminate when power is applied to the board.
