Troubleshooting

1.JetPack Flashing Issues

Issue	Resolution
NVIDIA APX not detected via `lsusb`	Try a different USB cable or port. Verify jumper is firmly placed on FC_REC and GND pins.
Flash script fails immediately	Re-run `sudo ./tools/l4t_flash_prerequisites.sh` and ensure all dependencies are installed.
`apply_binaries.sh` reports missing files	Verify rootfs was extracted into `Linux_for_Tegra/rootfs/` — not a subdirectory.
Flash stalls at rootfs copy	Use a USB 3.0 port. USB 2.0 is significantly slower.
Board boots to recovery on every power-on	Remove the jumper from FC_REC and GND before powering on.
`oem-config` does not launch on first boot	Reconnect display. If headless, SSH to board and run: `sudo /usr/sbin/oem-config-debconf`
NVMe not detected in `lsblk`	Ensure NVMe SSD is correctly seated in the M.2 Key-M slot and the retention screw is secure.

Issue	Resolution
Video node `/dev/video0` not found	Ensure the LVDS pin configuration was completed using `jetson-io.py`. Re-run the configuration if needed.
Black screen or no output from GStreamer	Verify the CSI cable is connected to CAM1. Check that `rc.local` was executed successfully.
Flash script fails	Ensure all dependency packages are installed. Re-run `apt install` and try again.
