3. Getting Started
3.1 Before you Begin...
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.
Caution: Make sure you are in a static-free environment and are following proper
procedures for handling ESD-sensitive electronic equipment.
3.2 Attaching Cables
Before attaching cables to the board make sure you know where pin 1 for each of the connectors is
located. Most connectors are keyed. However, some connectors use 2 x n headers, allowing the cable to
be plugged in backwards. Prime examples of this are the ADC and JTAG connectors.
There is silkscreen on the PCB identifying each connector and its pin 1 location. Make sure to pay
attention to the markings on the PCB for the pin 1 location. The pin 1 identifier is marked by either a
number or a triangle.
3.3 Before Applying Power...
In order to use the EDB9302A the user must first connect the peripherals to the EDB9302A as described
in the following procedure.
1. Place the EDB9302A on a static-free surface.
2. Make sure power switch S2 is in the OFF position.
3. Connect the 12V power supply provided to the board at J10.
4. Connect null modem serial cable provided in the kit from DB9 connector J2 to a serial port on a PC
or notebook (if so equipped).
5. Launch a terminal program, such as minicom or HyperTerminal. Configure the PC com port for:
38400 baud, 8 data bits, no parity, 1 stop bit, no flow control for WinCE and 57600 baud for Linux.
6. Connect the board to a network that has a DHCP server or to a router with DHCP capabilty enabled.
7. Connect a USB keyboard.
8. Turn power switch S2 to the ON position and the board will boot and start to display information in
the HyperTerminal window.
NOTE: The WinCE 5.0 binary is not provided on the support web site. If you erase the image on the
board, you will have to download the BSP provided by Cirrus Logic and compile it using Platform
Builder.
Due to changes in distribution policy, the Microsoft trial CD/DVD that was formerly included in the
kit is no longer available. Please refer to the card in the kit that describes how to download the
Microsoft trial software from the Microsoft web site.
