JetPack 4.6.1 is the latest release for the NVIDIA Jetson Developer Kits and modules. JetPack 4.6.1 is a minor update to JetPack 4.6 and includes TensorRT 8.2.1, DLA 1.3.7, VPI 1.2 with production quality python bindings and L4T 32.7.1

It also adds support for Jetson AGX Xavier 64GB and Jetson Xavier NX 16GB.

Visit JetPack 4.6.1 and L4T 32.7.1 page for more details.

JetPack 4.6 components:

  • L4T R32.7.1
  • CUDA 10.2
  • cuDNN 8.2.1
  • TensorRT 8.2.1
  • VisionWorks 1.6
  • OpenCV 4.1.1
  • Vulkan 1.2
  • VPI 1.2
  • Nsight Systems 2021.5
  • Nsight Graphics 2021.2
  • Nsight Compute 2019.3

The preferred way of upgrading the Jetson Nano 2GB Developer Kit, Jetson Nano Developer Kit or Jetson Xavier NX Developer Kit is to create a new SD card image and use it for the upgrade. For other Jetson models (and also on the previously mentioned ones) you can Install JetPack 4.6.1 using the SDK Manager on a host computer to flash the Jetson. The SDK Manager is available under the heading “NVIDIA SDK Manager Method” on the JetPack page. If you are using version 4.5+, you can upgrade via Debian package management tool (refer to the instructions here).

In order to reinstall older versions of JetPack, they are available in the JetPack Archive.

  1. Is it just a case of doing “sudo apt upgrade” if you already have a running system?

    P.S. Please could you do a blog post on the lack of availability of Jetson Nano Developer kits?

    1. I’m not sure I have much to share about the dev kit supply that isn’t already public knowledge. My understanding is that there is a world wide shortage of memory chips, ethernet chips and various other glue chips which everyone is competing for. During the original covid shutdowns a lot of the factory lines went down, and by the time they came back up a couple of things happened. One, a large part of the world went into lockdown. This lockdown meant an unprecedented demand for more hardware so that people could work from home.

      Secondly, the chip manufacturers had issues ramping up to full capacity because of staffing and supply shortages. Naturally the chip manufacturers had to make tradeoffs on which products to manufacture. For people in the industry, I don’t think that any of this is surprising if they understand how the supply chain works. Unfortunately a lot of that gets garbled when translated in the press. A lot of people weren’t listening when suppliers were saying that some of these issues won’t be solved until mid ’22 – early ’23. A lot of companies are redesigning their products to work around these supply shortages, but that takes time too. The recent lockdown of Shenzhen, China won’t help matters.

      For a fabless chip company like NVIDIA, you can see how this becomes an issue. They have to balance where allocations go and so forth. There have been even more issues with the graphics cards than the Jetsons. We are now seeing that NVIDIA is shipping Jetson modules to their partners ( who are offering them with their own carrier boards. That should help supply some, especially in the Xavier AGX/NX range. Orin dev kits should be shipping shortly. My understanding is that they have a huge back order for Jetsons in general, and are working on getting those filled.

      Some people try to compare that to Apple. However, the key take away is that Apple spent an unbelievable amount of money on their supply chain. They build their own specialized hardware. They have much better control, from the ground up if you will, over every item that is being manufactured that goes in their machines.

      It will be interesting to read “the lessons learned” papers, and watch to see how the various tech companies work to make their supply chains more reliable when stressed like this. It’s not clear if people will view it as a “100 year storm” or something that they need to fix immediately as part of their own survival. I think a lot of people in the west are nervous having the bulk of chips being manufactured in Taiwan right now.

      1. Thanks for the excellent reply. Jetson Nano dev kits are going for £450 on ebay when they only cost £100 new!

        1. There’s a market for them, that’s for sure. Yahboom is offering a Jetson Nano dev kit for around $300 USD ( using a Jetson module and their own carrier board. Even remembering that the NVIDIA dev kits are subsidized a little to get the price down, it will be interesting to see what where the market pricing will balance. I would guess that this isn’t Nanos year. However, when the new Nano comes out next year it promises to be more than interesting.

    1. Not my fault, blame it on NVIDIA! It’s been on their roadmap for some time now. I’ve heard that it will be quite an interesting product when it arrives next year.
