We are pleased to announce the production release of JetPack 6.2.1. JetPack 6.2.1 packages Jetson Linux 36.4.4 with Linux Kernel 5.15 and Ubuntu 22.04 based root file system. JetPack 6.2.1 is a minor upgrade over JetPack 6.2. This release supports all NVIDIA Jetson Orin modules and developer kits.

What’s new in JetPack 6.2.1

  • Added support for using Hardware Security Module (HSM) to sign boot images.
  • Resolved minor bugs, which improved the success rate of flashing with SDK Manager.
  • Addressed compatibility issues between JetPack 6.2 and the latest Docker release (v28.0.x).

You can install JetPack 6.2.1 with any of the methods below

  • SDK Manager: You can do a fresh install of JetPack 6.2.1 using SDK Manager.
  • Debian Package: If you have JetPack 6 already installed on Jetson AGX Orin Developer Kit or Jetson Orin Nano Developer Kit, you can upgrade to JetPack 6.2.1 using APT. Refer to the steps here.
  • SD Card: If you are using Jetson Orin Nano Developer Kit, you can download the SD Card image from JetPack 6.2.1 page and use Balena Etcher to prepare the SD Card with JetPack 6.2.1
  • Manual Flashing: If you prefer to install using the command line, you can flash Jetson device from a linux host by following steps here. Once Jetson Linux is flashed, you can install the compute stack using SDK Manager (using linux host) or by running “sudo apt update” followed by “sudo apt install nvidia-jetpack” on Jetson.

Note: JetPack 6.2.1 packages the same libraries, components and supports the same SDKs as JetPack 6.2.

I recently purchased an NVIDIA Jetson Orin Nano Developer Kit I am currently facing an issue while setting up the device.

After flashing the SD card using JetPack 6.2.1 (L4T 36.4.4) as per the official NVIDIA instructions, I inserted the card into the Jetson Orin Nano and powered it on. However, the system only displays a black screen, and nothing appears on the monitor. There is no signal output via HDMI, and the board does not seem to boot properly.

Here are some details of what I have tried:

  • Had the SD card flashed multiple times.
  • Checked power supply (5V/4A) and HDMI cable — both confirmed working.
  • Attempted with JetPack 6.0 as well, but the issue persists.

I kindly request your assistance in resolving this issue. Please advise if this could be a hardware issue or if any specific steps are recommended.
