JetPack 3.1 is a production software release for both Jetson TX1 and TX2, with Linux kernel 4.4 shared between both devices. In addition to bug fixes and improvements in the camera stack, JetPack 3.1 also includes updates to TensorRT 2.1 and cuDNN 6.0, delivering twice the inferencing performance for latency-sensitive applications. See our Parallel ForAll article, JetPack 3.1 Doubles Jetson’s Low-Latency Inference Performance.

Umm, I have to try it on Tegra X2 to see how great it is.
Have you tried YOLO on Tegra X2 btw? If so, would you please let me know your achieved time performance in FPS(video frames per second).
I tried Tegra X1 once on YOLO and its time performance was as much as 12 FPS , if I am not mistaken.
My current platform is tegra X2 so I am curious to know.
I just installed the CUDA, cudnn and TensorRT from the new Jetpack and couldn’t compile detectnet inference on my Jetson TX2.
It appears that some API was changed (I get a ‘Dims3 in namespace nvinfer1 does not name a type’ error). I would like to know how to bypass this.
Besides that, when I tried to reinstall the previous Jetpack version (3.0) to get my detectnet working again, the installation failed at the stage of populating the component manager (got an error without any more information).
I will be checking in the updated jetson-inference to reflect the changes shortly. Currently I am wrestling if I can make master backwards-compatible (i.e. using #ifdefs) so folks still on JetPack 3.0 / JetPack 2.3 can still compile.
bugreport: twice it has happened that on power on neither monitor nor network seems working.
Got resolved first time with reflash. Second time with multiple power off - power on attempts.
What could be the cause?
I got the same error with my fresh TX2. I don’t like this problem… I was already struggled a lot of problem today, and when i was prefer download the 3.1 update i thought this is the much more stable one… but no .nvidia still needs to be work on it. I hope your way is working on me. Thanks for sharing.
Edit: Yeah it worked for me. I just unplug the all cables and just re-plug the ethernet and keep resetting until it works. Thanks man!
I was able to flash Jetpack3.1 successfully on TX2. After that I was creating a bootable SD Card for TX2.
For jetpack3.0 I followed this(Run Jetson TX1 from SD Card - YouTube) link and was able to boot TX2 from SD Card rather than EMMC. But with JetPack3.1 it is not booting from SD Card after following the same procedure. It boots for 13 seconds, then says ‘Rebooting in 5 seconds’ and this cycle continues again and again.
It is booting successfully from EMMC.
Earlier in Jetpack3.0 extlinux.conf file used to look different. Can this be an issue here? Older Version:
Just a heads-up…the issue of apt-get update overwriting libglx.so is back. Anyone wanting to fix this can copy (from the driver package) “nv_tegra/nvidia_drivers.tbz2” over to “/” of the Jetson, and upack it to fix this (verify good/bad with “sha1sum -c /etc/nv_tegra_release”):
# On the Jetson, after copy of nvidia_drivers.tbz2 to "/"...
sudo tar xvfj nvidia_drivers.tbz2
# Verify fixed:
sha1sum -c /etc/nv_tegra_release
