Raspberry Pi Won't Boot
Troubleshooting guide for Raspberry Pi boot or SD card issues with ICATS.
If your ICATS system doesn't start or shows boot errors, follow these troubleshooting steps to identify and fix the issue.
Symptoms
- No power indicator LED when power is connected
- Boot errors or error messages on display
- System starts but doesn't reach ICATS interface
- Continuous reboot loop
- Corrupted display or scrambled screen
Likely Causes
- Power supply insufficient: Power supply doesn't provide enough current (needs 5V, 3A minimum)
- SD card corrupted: SD card may be damaged or corrupted
- Incorrect power supply voltage: Wrong voltage can damage system
- Hardware failure: Raspberry Pi hardware may be damaged
- Overheating: System may be overheating (check ventilation)
Fix Steps
- Check power supply: Verify power supply is correct (5V, minimum 3A). Check power indicator LED. If no LED, power supply is likely insufficient or incorrect.
- Verify connections: Ensure power supply is securely connected to Raspberry Pi and wall outlet. Try different power outlet.
- Check SD card: SD card is removable, check for damage. SD cards can fail. If corrupted, recovery may be needed.
- Check for overheating: Ensure system has adequate ventilation. Overheating can cause boot failures.
- Recovery procedure: If system won't boot, recovery procedure may be needed. Contact support for recovery instructions.
Warning: SD cards can fail over time, especially with frequent writes. If your SD card is corrupted, you may need a replacement. Contact support for recovery or replacement procedures.
