JetPack Flashing & Setup
📌 Using the Jetson AGX Orin Developer Kit (JetPack 7.2)? See the dedicated series: Jetson AGX Orin.
📌 Using the NVIDIA Jetson Orin Nano Super Developer Kit (JetPack 7.2.1)? See the dedicated series: Jetson Orin Nano.
For developers new to NVIDIA Jetson. Juxi Technology Jetson dev kits ship with Ubuntu 22.04 preinstalled — this guide is for reflashing or changing JetPack versions.
1. What is JetPack?
JetPack is NVIDIA's SDK bundle for Jetson platforms, including:
- Ubuntu system image
- CUDA / cuDNN / TensorRT
- Multimedia APIs (L4T)
Version mapping:
| Board | Recommended JetPack | OS |
|---|---|---|
| Orin NX / Nano | JetPack 6.x | Ubuntu 22.04 |
| Xavier NX / AGX | JetPack 5.x | Ubuntu 20.04 |
| Orin Nano Super (NVIDIA official kit) | JetPack 7.2.1 | Ubuntu 24.04 |
Juxi Technology Jetson Orin NX Super Dev Kit ships with Ubuntu 22.04 (JetPack 6.x ecosystem).
The NVIDIA Jetson Orin Nano Super Developer Kit — the official NVIDIA kit, sold by Juxi — ships without storage and without a preinstalled system (the bundled microSD card is blank). Install JetPack 7.2.1 with the Jetson ISO method: see the Jetson Orin Nano series.
2. Flashing Methods
Method 1: Official Image (Ubuntu Host)
# 1. Download the driver package for your board from NVIDIA
# 2. Extract and enter Linux_for_Tegra
cd Linux_for_Tegra
sudo ./apply_binaries.sh
# 3. Put Jetson into Recovery mode (hold REC + power)
# 4. Flash
sudo ./flash.sh <board-name> mmcblk0p1Method 2: SDK Manager (recommended for beginners)
- Install NVIDIA SDK Manager
- Connect Jetson to PC (Recovery mode)
- Select board → JetPack version → components (keep CUDA/TensorRT)
- Wait for flashing + first boot
⚠️ Flashing takes 20-60 minutes. Do NOT unplug during the process.
3. Troubleshooting
| Symptom | Check |
|---|---|
| Can't enter Recovery mode | Hold REC while powering on; verify with lsusb that an NVIDIA device appears |
| Flashing fails mid-way | Try a different data cable first; disable PC power saving; retry |
| Black screen after flash | Check display port (DP on Orin); re-enter Recovery and reflash |
| Version mismatch | Confirm board model matches JetPack version (silk-screen on board) |
4. Basic System Setup
4.1 Network & Repos
# Optional: mirror for faster apt
sudo sed -i 's|archive.ubuntu.com|mirrors.tuna.tsinghua.edu.cn|g' /etc/apt/sources.list
sudo apt update4.2 Verify GPU Environment
cat /etc/nv_tegra_release
nvcc --version
python3 -c "import torch; print(torch.cuda.is_available())"If PyTorch is unavailable, see PyTorch Compatibility on Jetson Orin.
4.3 Max Performance Mode (Orin)
sudo nvpmodel -m 0
sudo jetson_clocks4.4 Expand Root Partition
sudo systemctl enable --now nvresize
# or manually:
sudo resize2fs /dev/nvme0n1p15. FAQ
Q: No WiFi after flashing?
A: Orin core boards need an external M.2 WiFi module; check the dual-band antenna connection.
Q: How to enter Recovery mode?
A: Power off → hold REC (or BOOT) → power on / connect Type-C → verify lsusb shows NVIDIA Corp..
Q: Storage requirement?
A: ≥128GB SSD recommended (SD cards are a bottleneck). 256GB is the kit standard.
