FAQ ​

Before you start ​

What's in the box? The Jetson Orin Nano Developer Kit, a 19 V power supply, and a quick start and support card. There is no storage in the NVIDIA box: you supply the microSD card or NVMe SSD, the USB flash drive for the installer, and the monitor and keyboard — though the Juxi store bundle for this kit adds a 64 GB microSD card (per the store listing). See Quick Start.

Do I need to buy storage? Yes — unless you bought the Juxi store bundle, which already includes a 64 GB microSD card; it covers the target-storage requirement, so buy an NVMe SSD only if you want more capacity. (The bundled card ships blank, not pre-imaged — you install the system onto it with the Jetson ISO.) NVIDIA states: "Jetson Orin Nano Developer Kit does not include removable storage in the box, so choose either a microSD card or a NVMe SSD before starting setup." Buy a microSD card of 64GB UHS-1 or larger (NVIDIA's recommendation) if you received the bare NVIDIA box, or a PCIe NVMe SSD for one of the carrier board's M.2 Key-M slots. The kit has no eMMC: your card or SSD becomes the system's main storage. See Quick Start and Interfaces & Hardware Layout.

Can I still flash an SD-card image, like on earlier JetPack releases? No. Starting with JetPack 7.2, SD-card images are no longer supported. NVIDIA's instruction: "Do not flash the Jetson ISO to a microSD card — write it to a USB flash drive, then use it to install Jetson Linux onto your microSD card or NVMe SSD." The microSD card is still a valid install target; it is just no longer the medium you write the image to. The ISO USB stick is an installer, not a live USB — it cannot run a desktop, it only installs the system. See Flashing & Updates and JetPack 6 to 7 Migration.

What exactly do I need before starting? You need:

  • The kit and its included 19 V power supply.
  • A laptop or PC (Windows, Mac, or Linux) with at least 25GB of free space.
  • A USB flash drive, 16GB or larger, to hold the installer image.
  • Target storage: a microSD card (64GB UHS-1 or larger recommended) and/or an NVMe SSD — the Juxi store bundle already includes the 64 GB microSD card.
  • A DisplayPort monitor and a USB keyboard and mouse, or a USB-to-TTL serial cable for a headless setup.

NVIDIA's guide uses Balena Etcher to write the ISO to the USB stick — copying the file onto the stick is not enough. Step by step: Quick Start.

Do I need an Ubuntu PC? No, not for the recommended path. The Jetson ISO install runs on the kit itself; your PC only writes the ISO to a USB flash drive, and Windows, Mac, and Linux all work for that. An Ubuntu x86_64 host PC is only needed for the alternative methods — SDK Manager or the flash script — for example when you want to reflash a kit with the Super configuration. Note: the SDK Manager page documents Ubuntu 20.04 / 22.04 x86_64 hosts, while NVIDIA staff also report flashing successfully from Windows. See Flashing & Updates.

Where is the microSD slot? It is on the underside of the Jetson Orin Nano module, not on the carrier board edge. Insert the card before you boot the ISO installer; the installer only offers storage that is already installed. To change the card later: power off, swap in the new card, and re-run the JetPack 7.2.1 ISO installer with it inserted — JetPack 7.2 and later have no card image to write. See Interfaces & Hardware Layout and Quick Start.

Setup ​

My kit is new — why does the guide say update the firmware first? JetPack 7.2 and later installs require JetPack 6.x-generation UEFI/QSPI firmware on the kit — version 36.x or newer. Kits that shipped with older factory firmware must complete NVIDIA's "JetPack 6.x Update Path" before the JetPack 7.2.1 ISO can boot. To check the version: power on with a monitor attached and press Esc repeatedly at the boot splash; the UEFI menu shows the firmware version near the top. If it shows 36.x or newer, continue; if it is older than 36.0, do the update path first. See Quick Start, Flashing & Updates, and the Glossary for terms such as QSPI and capsule update.

How long does setup take? NVIDIA does not publish a total setup time. The official instructions say you may see white text scrolling on the screen for several minutes, and you should wait for the installer to complete and reboot when prompted. User reports range from about 15 minutes to about two hours for a microSD-card install (user reports, unconfirmed), and first boot then adds the Ubuntu setup screens (language, network, username). See Quick Start.

What if the installer skips the username/password screens? This matches a known report: the QSPI capsule prompt timed out. The installer asks you to confirm a firmware (QSPI) update and waits only 30 seconds — if the prompt is missed, later steps can fail, and the language, network, and username screens may never appear; the next boot can then stop at a black screen with a cursor. The fix from the official guide: restart the installation and press Y when the capsule prompt appears. Some users also cleaned leftover partitions before retrying, or installed with SDK Manager instead (user reports; NVIDIA staff acknowledged the thread). See Troubleshooting.

Important When the installer shows the QSPI capsule update prompt, press Y within 30 seconds. NVIDIA calls this "the most commonly missed step".

How do I get a serial console? Connect a USB-to-TTL serial cable to the Button Header: RXD pin 3 connects to the adapter's TX wire, TXD pin 4 connects to the adapter's RX wire, and GND pin 7 connects to the adapter's ground wire. Then open a serial console on your PC, power on, and press Esc during the pre-boot screen to enter UEFI / Boot Manager — you can complete the whole ISO installation this way. One honest gap: NVIDIA's pages say "open a serial console on your PC" but do not state a baud rate or a terminal program. When the kit is connected to a PC over USB-C in device mode, it also presents a "USB Serial device for serial terminal access". See Interfaces & Hardware Layout and Troubleshooting.

Power and performance ​

Why is there no 25W / MAXN SUPER option? Your kit was flashed with the non-Super boot configuration, so only 7W and 15W modes appear. This was documented JetPack 7.2 ISO issue 6279443: ISO installs kept the pre-update profile instead of switching to "Super". JetPack 7.2.1 fixes this for new installs — the ISO "now flashes the Jetson Orin Nano Developer Kit with Super Mode flashing configuration by default"; NVIDIA does not say whether a 7.2.1 reinstall converts a 7.2.0-ISO kit. Check /etc/nv_boot_control.conf: a Super configuration shows a -super suffix. To fix an existing 7.2 install, reflash with the Super configuration from an Ubuntu host (SDK Manager or the flash script); the Power Mode menu then offers 15W, 25W (default), and MAXN SUPER. See Verify Your System, Troubleshooting, and Flashing & Updates.

Juxi note: A community in-place fix exists (edit /etc/nv_boot_control.conf, reconfigure the bootloader, remove /etc/nvpmodel.conf, reboot). Multiple users report success, but NVIDIA has not endorsed it and one user reported a boot loop.

AI workloads ​

How big a model can 8 GB run? The 8GB of LPDDR5 is unified memory, shared by the CPU, the GPU, and the operating system — about 7.6GB is usable after firmware and kernel reservations. NVIDIA's published guidance: with 4-bit quantization and memory-efficient runtimes, you can fit LLMs up to roughly 10B parameters and VLMs up to roughly 4B parameters. TensorRT Edge-LLM's official Orin Nano 8GB benchmarks cover models up to 2B, and that is the largest model class NVIDIA benchmarks on this kit. A model can fail to load even when the file seems to fit, because the KV cache also needs memory; 7.4GB and 16GB GGUFs have failed to load on an 8GB kit (user reports). See Local LLMs on 8GB and Memory Efficiency.

Support and service ​

What is the support route? Start with NVIDIA's official Troubleshooting page, which covers the five common setup problems: the ISO does not boot, no display output, the installer does not show target storage, a firmware update is needed, and a Docker permission error. For platform questions, use the NVIDIA Jetson developer forums, listed on the official Additional Docs page; search before posting, and include the output of cat /etc/nv_tegra_release.
