V. Operating System Installation and Use

5.1 Supported OS

VxWorks 5.5/6.x (Officially Recommended)

PowerPC Linux (2.6/3.x) QNX 6.x

LynxOS

5.2 VxWorks Quick Boot

Set the IP address of ETH0 in the firmware, enable TFTP

Load the VxWorks image from TFTP

Or directly boot from the on-board NOR Flash

Login: target, Password: (empty)

5.3 Network Configuration (Linux Example) bash

Operation

ifconfig eth0 192.168.1.100 netmask 255.255.255.0

ifconfig eth1 192.168.1.101 netmask 255.255.255.0

Six. Hardware Maintenance and Calibration

6.1 Regular Maintenance (every 6 months)

Dust removal: Brush + compressed air (≤ 0.5 MPa)

Check screws: Fixed screws, PMC panel

Interface check: RJ45, DB9, VME gold fingers (no oxidation / deformation)

Firmware upgrade: Latest firmware from the official website (V2.4.0+)

6.2 Battery Replacement (NVRAM/RTC)

Battery model: CR2032 (3V)

Life: 5 years

Replacement: Power off → Remove old battery → Place new battery with positive pole upward → Power on and calibrate

Seven. Fault Troubleshooting (Common Problems)

7.1 No response upon power-on (PWR does not light up)

Check +5V power supply of the chassis (current ≥ 5A)

Check fuse of the board (F1)

Reinsert and reposition the board, clean VME gold fingers

7.2 RUN does not light up / ERR red light

RUN does not light up: Firmware damage → Reburn Flash

ERR constantly on: Memory failure → Replace SDRAM

ERR flashing: VME bus conflict → Check address mapping

7.3 No network connection

Check Ethernet 0/1 network cables / switch

Firmware / system IP address conflict

Network port damage → Enable backup network port

7.4 No output from serial port

Baud rate / parameters error (must be 115200 8N1)

Serial port cable reversed (TX ↔ RX)

Console disabled → Firmware restore default
