Firmware Backup

NVIDIA NUC / Jetson Firmware​

Prefer using the exact files you originally flashed the Jetson with, since NVIDIA's download center may serve slightly different point releases over time.

  1. Locate the flashing files you originally used (usually in the folder where you first set up the NUC) and upload them directly to Firmware Backup/NVIDIA/NUC Firmware/:
    • Jetson_Linux_R<version>_aarch64.tbz2
    • Tegra_Linux_Sample-Root-Filesystem_R<version>_aarch64.tbz2
If you lost the original files

Check the installed L4T (Linux for Tegra) version on the NUC:

cat /etc/nv_tegra_release

Then go to the NVIDIA Jetson Download Center and download the Driver Package (BSP) and Sample Root Filesystem matching that exact L4T version. Note that this is a fallback only — it may not be byte-identical to what you originally flashed.

  1. Upload both files to Firmware Backup/NVIDIA/NUC Firmware/ in Google Drive.

Router Configuration​

These steps apply to Cudy routers. If your project uses a different router brand, check that manufacturer's documentation for the equivalent backup/restore procedure, since menu names and file formats vary widely between vendors.

  1. Connect to the router's network and open its admin panel at http://cudy.net or http://192.168.12.1.
  2. Go to Advanced Settings → System → Backup/Restore (on some models this is under Settings → Advanced → System).
  3. Click Generate Backup (or Backup) and download the resulting file.
  4. Rename the downloaded file router_config_backup.bin and upload it to Firmware Backup/Router/ in Google Drive.
Restoring the Cudy router

In the same Backup/Restore section, click Browse, select the backup file, then click Restore and wait for the router to reboot.
