JetPack 4.2 — L4T R32.1 release for Jetson AGX Xavier, Jetson TX2, and Jetson Nano

Hi Roman, one of our teammates should be looking into your issue shortly, please stay tuned.

The retropie script might actually run to transform the system into a multi-system emulator. You can try following these instructions here.
The retropie script builds everything from source and is already working on arm. I have tested it on another arm64 dev board so it does run on the architecture, however much of the nicely optimised, hand tuned arm asm was not enabled on build (this may have changed, as the script may have been updated). At least in part because of that the performance was better on the Pi.

Please also be aware that the retropie script makes a lot of systemwide modifications, so if you want to try this, it’s highly suggested you dedicated a microsd card to the purpose.

is it possible to upgrade the kernel to K4.14 in the future?

Hi newopinion1012, K4.9 is for long term support across Jetson’s, eventually a newer version will be adopted, but the concrete schedule for that is TBD. We’ve also submitted the patches for Nano upstream, so hopefully in the future it may be easier to change kernel versions.

I have done the jetpack, it is meet our software design requirement. but i want to know what’s time i can get the hardware design guide of the kernel board.
Now we have design the support test board for nano kit, i want to use the kernel board in our system.

Hi luo.jh, we are preparing to release the Nano module hw design docs later in June closer the release of the production module, thanks for your patience.

Does jetson-nano have ubuntu16.04 sd card img?

Hi alberto18_90, if you already have these packages on your host, you can try disabling these host-side packages through the installer UI. If you wish you can have it only install components to your Jetson.

Hi,

Just FYI, when trying to download the latest Jetson Nano image from Australia I get some heavy throttling, which results in a download time of 11 hours.

If I download via VPN through the US, I don’t get throttled and it only takes 25 minutes.

Does your host throttle connections from AUS for a particular reason?

No it shouldn’t be, let me check with our web team to see if there is an issue with the CDN in your region. Thanks for letting us know.

I am trying to flash the nano using sdk manager via barrel jack, usb cable and Two pin header (j48 jumper for barrel power and jumper frc pins) in manual mode. The nano boots fine with a nano dev kit image 5/30/2019. Do i need to get a newer image for the nano?

The flash fails with an error Error: Flash Jetson Nano : lost connection around the 11% mark

Any idea

Found the issue after reader the forum. I needed to install python 2.7

Sudo apt install python-minimal

Did the trick

Our CDN provider said there was an outage which caused congestion in your region during the timeframe you reported.

Could you try downloading from your AUS connection again and see if the speed is better now? Thanks.

Using the sdkmanager for nano (or TX2 or Xavier) on Ubuntu 18.04, step 3 fails on install for Drivers for Jetson Nano with:

Hi Metricon, we recently refreshed this file on the server, can you try again when you get a chance?

You may also want to try installing the bzip2 version from this post, it seems the package was updated recently:

https://devtalk.nvidia.com/default/topic/1056381/jetson-agx-xavier/jetpack-4-2-xavier-install-failed/post/5355914/#5355914

Thanks. Updating bzip2 from the link fixed the issue.

Hello.
I want to install the JetPack 4.2 for Xavier AGP.
When I run sdkmanager on the PC I am getting the “Opps No SDKs available for you account…” error.
My ID is:
NVIdia Developer Program 874688

This should be on top of the solution post as a first solution, It took me two working days and countless environment setups to finally have found this thread.

Hello.
After spending two days fixing accounts I finally found the problem for - “Opps No SDKs available for you account…” printed by sdkmanager after login.

It is because the script returns ETIMEDOUT error during the download of sdkml1_repo.json, installation get confused and prints “No SDKs available” nonsense message.

After I fixed the network routing and the firewall installation continued to next step Ok!

NVIDIA - Please update documentation and fix the sdkmanager to report correctly network timeout errors!

Hi, I just downloaded https://developer.nvidia.com/embedded/dlc/l4t-sources-32-1-jetson-nano - but trying to extract kernel_src.tbz2 I get a decompression error (bzip2: Jetson-Nano-public_sources.tbz2: data integrity (CRC) error in data). I tried this on Ubuntu 16.04, 18.04 and natively on the Jetson Nano - could you please check the file intergrity and possibly upload a non-corrupted version?
Edit: sorry for the noise - using a freshly installed x86_64 Ubuntu 18.04 I was able to extract the files.
