One item not listed above is the Flash device. It is located on the bottom side of the board, under item C. There are no jumpers on the board. The only "jumper" is the serial boot pushbutton. This button is used when the developer wants to use the Cirrus Logic download utility to put new code into Flash memory. ©...

The developer will find it useful to have some additional hardware not provided in the EDB9302A kit. Items such as a USB keyboard and a set of powered speakers can make using the EDB9302A and the software installed on the board more enjoyable.

Technical Reference Manual 4. EDB9302A Circuit Description This chapter makes reference to the schematics in Appendix A and discusses the main circuit functionality of each schematic page. A detailed block diagram of the EDB9302A Engineering Development Board is shown below. JTAG 20 pin USB 2.0...
Page 10: Circuit Operation
The pinout of the headers matches common IDC10-to-DB9 cables. One such cable is included with the kit. All UART signals are level shifted from TTL to RS-232. The CIR uses an enhanced GPIO (EGPIO) line to communicate to the EP9302 device. © Copyright 2006 Cirrus Logic, Inc. DS653DB1...

The “Serial Boot” pushbutton, S1, is used to configure the board to perform a serial boot. A serial boot is used to program the Flash device with the Cirrus Logic download utility. Instead of using jumpers, a pushbutton is used. Simply hold the pushbutton down while pressing and releasing the reset pushbutton, S3.

WinCE 5.0 Flash image with Linux or some other software, and then later desires to put the WinCE 5.0 image back into Flash, they must obtain the WinCE 5.0 BSP from their Cirrus Logic FAE and build the image themselves using the trial version of Platform Builder™ or with a version of Platform Builder they have purchased.

• Linux 2.6 • Board utilities • Tools Contact a Cirrus Logic FAE for information regarding the following. • WinCE 5.0 BSP The documents listed above are updated periodically and may be more up to date than the information in this document.
Page 16: Appendix A. Schematics
EDB9302A Technical Reference Manual Appendix A. Schematics The schematics for the EDB9302A Development Board are located on the Cirrus Logic Developer’s Forum website ( arm.cirrus.com ). The schematics are provided in Adobe’s portable document format (PDF) and PADS™ format. OrCAD™ versions of the schematics are not available.

The instructions and screen shots in this Appendix make reference to the SolarWinds 6.0 TFTP server program. This program is not provided by Cirrus Logic. Other TFTP server programs may work equally well but will need to be verified by the developer.

3. Once the program is installed, run the TFTP Server program. 4. Configure the TFTP Root directory to point to C:\TFTPROOT. 5. Select the Security Tab and make sure the Client access is Transmit and Receive files. See the pictures below. © DS653DB1 Copyright 2006 Cirrus Logic, Inc.
Page 32 Note: Note: You may get an IP address of 127.0.0.1 because the EDB9302A board does not have the boot loader code programmed yet. This is ok. Simply quit the TFTP server program. Instructions on when to start the program will be given during the board programming section.

(1) stop bit (8-N-1) and NO hardware control flow. It should look like the picture below when complete. Note you have to "Disconnect" in order to make configuration changes. Click "Call" once the configuration is complete. © DS653DB1 Copyright 2006 Cirrus Logic, Inc.
Page 34: Board Programming Setup
Board Programming Setup 1. At this point, the RJ45 Ethernet port on the Windows PC is configured, HyperTerminal is running, the TFTP server is running, the Cirrus Logic software has been downloaded to the C:\TFTPROOT directory and the board is powered up.

Page 36 6. The next step is to configure the board so it can communicate via Ethernet. Type "fconfig" in the HyperTerminal window and set all parameters like the picture below. Note: You may have to hit the Backspace key to change some parameters and then type in the new parameter. © Copyright 2006 Cirrus Logic, Inc. DS653DB1...
Page 37 9. Press and release pushbutton S3 "/POR" for the changes to take effect. You should see the following. Note: It will say "No image 'image_name' found". That is ok for now. We have not downloaded and programmed those images into Flash yet © DS653DB1 Copyright 2006 Cirrus Logic, Inc.
Page 38 It is acceptable to make the partition larger than the exact image file size. Once the board has been programmed, reset the board and wait for it to boot up. You will see boot information in the HyperTerminal window. © Copyright 2006 Cirrus Logic, Inc. DS653DB1...
