1.2 Introduction

The KS8695PX Demonstration Board is intended to provide a convenient means to

evaluate the functionality of the new KS8695PX Integrated Multi-Port PCI Gateway and

jump start software development. Micrel provides a complete Linux based SOHO Router

software solution with which to evaluate the KS8695PX functionality. The SOHO router

software includes a web based configuration utility to allow quick and easy device setup.

The demonstration board also has hardware support for a mini-PCI connector to address

the 802.11a/b/g wireless gateway router market, as well as a host of other applications

that take advantage of the multitude of devices that connect to PCI, miniPCI, or cardbus.

3.0 Getting Started

This section describes how to get the KS8695PX Reference Board up and running with

Micrel’s SOHO router software and your PC. You will need:

· Micrel KS8695PX Demo Board

· Micrel provided 5.0 V power supply.

· 1 Category 5 ethernet cable for the LAN, 1 Category 5 ethernet cable for the

WAN.

· 1 Null serial cable with female to female connectors for console port connection.

(Optional).

· 1 PC.

1. Connect the included 5.0 V power supply to the KS8695PX reference board and

plug it into a wall socket. When the board is plugged in, or when the reset button

on the board is depressed, you should see a flashing LED pattern. This is the

power on self-test (POST).

2. The ports on the KS8695PX board are labeled as WAN and LAN. Connect a PC

to one of the LAN ports and Internet service to the WAN port on the board.

Internet service can be replaced with a PC running a web server.

3. Connect a null serial cable (Optional) from the serial port of the KS8695PX

Reference Board to a PC to monitor Linux kernel boot time messages. After the

boot, a shell prompt is displayed for accepting Linux shell commands. For

instance, type the “ls” command to list the files of the current directory.

3.1 Configuring PC COM port settings

The Windows Hyper Terminal can be used as a console to communicate with the

KS8695PX Reference Board. The configuration settings for serial

communication are shown below.

The default base address for the KS8695PX system configuration registers is 0x03ff0000.

After power up, the user is free to re-map the memory for his/her specific application.

Here is an example of the memory space remapped for operation:

Please see the KS8695PX Detailed Register Description document for more information.

4.1 KS8695PX

4.1.1 Board Reset

The KS8695PX reference board provides both a power on reset and a push button reset,

as well as circuitry to reset the board using the Multi-ICE. At power on, the board is

automatically reset. The user can also press S1, the reset button on the board for a

manual reset. After any reset, expect the LEDs to flash indicating the power on self test.

4.1.2 System Clock

The system clock is generated using a 25 MHz crystal (Y1). The crystal is connected to

the XCLK1 and XCLK2 inputs on the KS8695PX. The clock is specified as 3.3V

tolerant, +/- 100 ppm.

4.1.3 Jumpers

There are a number of jumpers and test points on the board to facilitate configuration and

testing of the KS8695PX. Below is a table that lists the jumpers and test points, their

purpose, and the recommended configuration on the board.
