Evaluation Board Manual

Getting Started

2.3 Hardware Installation
Follow these instructions to get your new IQ80960RM/RN platform running. Be sure all items on
the checklist were provided with your IQ80960RM/RN.
Warni ng: Static charges can severely damage the IQ80960RM/RN platforms. Be sure you are properly
grounded before removing the IQ80960RM/RN platform from the anti-static bag.

2.3.1 Battery Backup

Battery backup is provided to save any information in SDRAM during a power failure. The
IQ80960RM/RN platform contains four AA NiCd batteries, a charging circuit and a regulator
circuit. The batteries installed in the IQ80960RM/RN platform are rated at 600 mA/Hr.
SDRAM technology provides a simple way of enabling data preservation through the self-refresh
command. When the processor receives an active Primary PCI reset it issues the self-refresh
command and drives the SCKE signals low. Upon se eing this condition, a PAL on the
IQ80960RM/RN platform holds SCKE low before the processor loses power. The batteries
maintain power to the SDRAM and the PAL to ensure self-refresh mode. When the PAL detects
PRST# returning to inactive state, the PAL releases the hold on SCKE.
The battery circuit can be disabled by removing the batteries. LED CR4 indicates when the SDR AMs
have sufficient power. If the batteries remain in the evaluation p latform when it is depowered and/or
removed from the chassis, the batteries will maintai n the SDRAM for approximately 30 hour s. Once
power is again applied, the batteries will be fully c harged in about 4 hours.

2.3.2 Installing the IQ80960RM/RN Platforms in the Host System

If you are installing the IQ80960RM/RN platform for the first time, vis ually inspect the board for
any damage that may have occurred during shipment. If there are visible defe cts, return the board
for replacement. Follow the host sys tem manufacturer’s instructions for installing a PCI adapter.
The IQ80960RM/RN platform is a full-length PCI adapter and requires a PCI slot that is free from
obstructions. The IQ80960RM/RN platform is taller than specified in the PCI Local Bus
Specification Revision2.1. The extended height of the board will require you to keep the cover off
of your PC. Refer to Chapter 3 for physical dimensions of the board.

2.3.3 Verify IQ80960RM/RN Platform is Functional

These instructions assume that you have already install ed the IQ80960R M/RN platfor m in the hos t
system as described in Section 2.3.2.
1. To connect the serial port for communicating with and downloading to the IQ8096 0RM/RN
platform, connect the RS-232 cable (provided with the IQ80960RM/RN) from a free seri al
port on the host system to the phone jack-style connector on the IQ809 60RM/RN platform.
2. Upon power-u p, the red FAIL LED turns off, indicating that the proces sor has passed its self-test.
3. If you have IxWorks installed in the flash ROM, the user LEDs display the bi na ry pattern 99H.
In the IxWorks development environment, raw serial input/output is not used. Instead, the
Wind DeBug (WDB) protocol is run over the serial port, to allow communication with
Tornado development tools. If t he terminal emulation package is running at 1 15,200 baud, the
letters “WDB_READY” display prior to launching in the WDB serial protocol.
