Getting Started

2.3 Hardware Installation

Follow these in st ructions to get your new IQ80960RM/RN platform running. Be sure all items on the checklist were provided with your IQ80960RM/RN.

Warning: Static charges can severely damage the IQ80960 RM/RN platforms. Be sure you are prop erly

grounded before re moving the IQ80960RM/RN platform from the anti-stati c bag.

2.3.1 Battery Bac ku p

Battery backup is provided to save any information in SDRAM during a power failure. The IQ80960RM/RN platform contains four AA NiCd batter ies, 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 drive s the SCKE signals low. Upon seeing this condition, a P A L on the IQ80960RM/RN platform holds SCKE low before the process or los es power. The batteries maintain power to the SDRAM and the PAL to ensure self-refresh mode. When the PAL detects PRST# returning to ina ctive state, the PAL releases the hold on SCKE.

The battery circuit can be disabled by removing the batteries. LED CR4 indicates when the SDRAMs have sufficient power. If the batteries remain in the evaluation platform when it is depowered and/or removed from the chassis, the batteries will maintain the SDRAM for approximately 30 hours. Once power is again applied, the batteries will be fully charged in about 4 hours.

2.3.2 Installing the IQ80960RM/RN Platforms in the Host System

If you are installing the IQ80960RM/RN pla tform for the first time, vis ually inspect the board for any damage that may have occurred during shipment. If there are visible defect s , return the board

for repl acement. Follow the host system manufa cturer’s instructions for inst alling a PCI adapter. The IQ80960RM/RN pl atform is a full-leng th P CI adapter and requires a PCI s lot that is free from obstructions. The IQ80960RM/RN platform is taller than specified in the PCI Local Bus Specification Revision 2.1. The extended height of the board will require you to keep the cover off of your PC. Refer to Chapt er 3 for physical dimensions of the boa rd.

2.3.3 Verify IQ80960RM/RN Platform is Functional

These instruct ions ass ume that you have alrea dy install ed the IQ8 0960RM/RN pla tfo rm in the host system as described in Section 2.3.2 .

1. To connect the serial port for communicating with and downloading to the IQ80960RM/RN platform, connect the RS-232 cable (provided with the IQ80960RM/RN) from a free serial port on the host system to the phone jack-style connector on the IQ80960RM/RN platform.

2. Upon power-up, the red FAIL LED turns off, indicating that the processor has passed its self-test.

3. If you have IxWorks installed in the flash ROM, the user L EDs displ ay the bina ry pat tern 99H. In the IxWorks deve lopment environment, raw serial input/output is not used. Instead, the Wind DeBug (WDB) protocol is run over the serial port, to allow communica tion with Tornado developm ent tools. If the terminal emulation package is run ning at 115, 200 baud, the letters “WDB_READY” display prior to launching in the WDB serial proto col.

4. If you have MON960 installed in th e flash ROM, pre ss <ENTER> on a term inal connected to

the IQ80960RM/RN platform to bring up the MON960 prompt. MON960 automatically adjusts its baud rate to match that of the termi nal at start-up. At baud rates other than 9600, it may be necessary to press <ENTER> several times.

2.4 Creating and Downloading Executable Files

To download code to the IQ80960RM/RN platform running IxWorks, consult Wind Riv er documentation on the supplied TORNADO for I IQ80960RM/RN platform, your compiler produces an ELF-format object file.

To download code to the IQ80960RM/RN platform running CTOOLS, consult the CTOOLS documentation for information regarding compiling, linking, and downloading applications. During a download, MON960 checks the link address sto r ed in the ELF file, and stores the file at that locati on on the IQ80960RM/RN platform. If the executable file is linke d to an invalid addres s on the IQ80960RM/RN platform, MON960 aborts the downloa d.

3.2.1 SDRAM Performance

The IQ80960RM/RN pla tform uses 72-bit SDRAM with ECC or 64-bit SDRAM without ECC. SDRAM allows zero data-to-data wait state operation at 66 MHz. The memory controller unit (MCU ) of the i 96 0 of four enables se am less read/write burs ting of long data strea ms, as long as the MCU does not cross the page boundary. Page boundaries are naturally aligned 2 Kbyte blocks. 72-bit SDRAM with ECC allows a maximum throughput of 528 Mbytes per second.

Both 16 Mbit and 64 Mbit SDRAM devic es are supported. The MCU keeps two pages per bank open simult aneous ly for 16 Mbit de vices a nd 4 pages pe r bank fo r 64 Mb it device s.

3.2.2 Upgrading SDRAM

The IQ80960RM/RN is equipped with 16 Mbytes of SDRAM with ECC ins erted in the 168-pin DIMM socket. The memory may be expanded by inserting up to a 128 Mbyte module into the DIMM socket. The various memory combinations are shown in Table 3-4. Only 168-pin +3.3V SDRAM modules with or without ECC rated at 10 ns shoul d be us ed on the IQ80960RM/RN platform. The column labeled ECC dete rmines if that particular memory configuration can be used with ECC.

3.6 Battery Backup

Battery backu p is provided to save any inform ation in SDRAM during a power fail ure. The IQ80960RM/RN platform contains four AA NiCd batteries, a charging circuit and a regulator circuit. The bat teries installed in the IQ80960RM/RN platform are rated at 600 mA/Hr.

SDRAM technology provides a simple way of enabling data preservation though the self-refresh command. When the processor receives an active Primary PCI reset it will issue the self-refresh command and drive the SCKE signals low. Upon seeing this condition a PAL on the IQ80960RM/RN platfor m will hol d SCKE low before the proce ssor los es power. The batteries will maintain power to the SDRAM and the PAL to ensure self-ref r esh mo de. When the PAL sees PRST# r et urning to in ac t iv e s t at e th e PAL will re lease the hold on SCKE.

Hardware Reference

The battery circuit can be disabled by removi ng the batteries. LE D CR4 indicates when the SDRAMs have suff icient power. If the batteries remain in the evaluation platform when it is depowered and/or removed from the chassis, the batteries will maint ain the SDRAM for approximately 30 hours. Once power is again applied, the batteries will be fully charged in about four hours.

3.7 Loss of Fan Detect

The i960 RM/RN I/O processor can be cooled by an active heat sin k mount ed on top. The fan provides a square wave output that is monitored by a comparator circuit on the IQ80960RM/RN platform. The frequen cy of the fan output is approxi mately 9K RPM. If the frequency falls below approximately 8K RPM the circuit will provide an interrupt to the processor.

Note: The standard production boards will be shipped with attached pass ive heat sinks. In the case of

utilizing a passive heat sink, the proces s or never sees an interrupt from not having a fan.
