We’re pleased to announce that a developer preview release of JetPack 3.2 is now available for Jetson TX2!
Highlights include support for TensorFlow models in TensorRT 3.0, up to 15% perf/W improvement for DL applications, out-of-the-box kernel support for Docker, and support for Ubuntu 16.04 on your host PC (Ubuntu 14.04 on your host PC will also work, except cross-development packages for OpenCV and VisionWorks will be unavailable on that host PC). The preview is only for TX2. For more info, please view the full Release Notes.
Hi,I downloaded JetPack 3.2 DP, but when it began to install, it seems to install the 3.1 version of JetPack, Is there something to config? (my OS is ubuntu 16.04)
Hi Fo2sh44, JetPack installs packages for OpenCV on both the host (cross-development) and the target Jetson. Unless disabled, it updates the host and installs OpenCV on Jetson. Running JetPack with the default options will flash your Jetson with the latest L4T and default vanilla Ubuntu image.
Hi dusty_nv Thanks for your reply!,I’m using TX2,and I tried several times, but it only get 3.1 version to install. I also checked the manifest.json and repository.json, and do not find anything about the 3.2 verison related file(cuda is 8.0.84 .etc). btw, my OS is ubuntu 16.04.03 Gnome,It has some effect on this?
It may be related to which country you are downloading from, but I’ve just downloaded it from Europe and installed without problem:
head -1 /etc/nv_tegra_release
# R28 (release), REVISION: 2.0, GCID: 10136452, BOARD: t186ref, EABI: aarch64, DATE: Fri Dec 1 14:20:33 UTC 2017
Did you download and install from a fresh directory or reused a previous JetPack directory?
I have created a JetPack-3.2 folder at the same level as JetPack-3.2-installer.run, cd into this folder and there run …/JetPack-3.2-installer.run (sorry not sure about its name, I’m on TX2, no longer on host).
Just looked at opencv3.3.1 included, and feel very disappointed…no CUDA nor gstreamer support. I cannot understand how nobody in nvidia is able to generate a better config for this:

-----------------------------------------------------------------
What I mean to ask is whether I will be able to use JetPack 3.2 GA to flash/provision TK1, and move to use Ubuntu 16.04 on the host PC. I don’t mind if it will still be L4T 21.6 for TK1.
/etc/nv_tegra_release seems to show the R28 release :
R28 (release), REVISION: 2.0, GCID: 10136452, BOARD: t186ref, EABI: aarch64, DATE: Fri Dec 1 14:20:33 UTC 2017
However, it is unclear to me where the <JetPack_Install_Dir> is on TX2.
I suspect that the installer did not actually install all the components in step 14 after rebooting the system. If it is the case, how do I resume from that point ?
