Troubleshooting

Common issues and their resolutions for JoingAI products.

Device Not Detected

• Confirm the FAKRA / coaxial cable is firmly connected at both ends.
• Check that PoC power is enabled for the affected camera channel.
• Verify the driver has been loaded (lsmod | grep fzcam).
• Re-run sudo fzcam_ui to reconfigure the camera node.

No Video Output

• Confirm the camera is configured for the correct resolution and frame rate.
• Validate the CSI lane mapping matches the carrier board pinout.
• Try a different /dev/videoN device node.

Power Issues

• Ensure the input voltage is within 12V–24V DC.
• Check that the total current draw does not exceed the adapter's rating.
• Inspect fuse or protection circuitry if the board fails to power on.

ESD Damage Prevention

• Always wear an anti-static wrist strap when handling bare boards.
• Transport and store boards in anti-static bags.
• Avoid placing boards on carpets or other static-prone surfaces.
