Do I have to manually download and unzip it from the official website?I don’t want to do that.

kayccc · January 7, 2026, 7:12am

That’s still under preparation, please wait for our announcement to try, Thanks

wpceswpces · January 7, 2026, 7:13am

Okay, looking forward to it. Thank you for the answer!

Here’s what I did a bit earlier tonight.

You’re really doing an excellent job! Has there been any improvement in the 100G network with this version? By switching to threaded mode, I was only able to reach over 40G with TCP in the previous version (r38.2.1), and UDP was only a few Mbps.

wpceswpces · January 7, 2026, 2:18pm

hi,kayccc

But I want to know where to make the announcement for it to be valid. I could already see it on the official website yesterday.

JetPack SDK Downloads and Notes | NVIDIA Developer

kayccc · January 8, 2026, 1:34am

We have posted the JP7.1 announcement at this morning - NVIDIA Jetson T4000 and NVIDIA JetPack 7.1 now available: Accelerate AI Inference for Edge and Robotics - Jetson & Embedded Systems / Jetson Thor - NVIDIA Developer Forums

Please get it a try now. Thanks

wpceswpces · January 8, 2026, 1:39am

hi,kayccc

It can now be automatically pulled except for the kernel.It got blocked.

kayccc · January 9, 2026, 6:48am

Is this still an issue now?

Could you confirm whether syncing sources is slower but still works without issues, right?
This is because of nv-tegra git server. If you are seeing issues because of slowness of nv-tegra, you could use the new git server to sync - nv-tegra · GitLab

wpceswpces · January 9, 2026, 6:55am

Sorry, all the code except for the kernel can be synced. I’ve given up on manually extracting the tar package.

wpceswpces · January 19, 2026, 2:08am

I just tried again, but I can’t pull the kernel down. It’s not slow, it just doesn’t move at all. There’s only a control folder and a .git folder. Other device tree sources that are smaller can be pulled down

Hi,
Please try attached source_sync.sh and see if you can successfully download kernel source code.
source_sync.zip (4.9 KB)

whitesscott · January 19, 2026, 5:31am

Hi wpceswpces,

Last week I looked at the 7.1 source_sync.sh and it’s been updated and now defaults to the most recent Jetpack. I just ran following to pull sources. I think gitlab requires a person to logged into it; but I don’t know how that would work as I doubt gitlab.com is checking my web browsers cookies from within source_sync.sh. So nv-tegra wins below.

cd ~/nvidia/nvidia_sdk/JetPack_7.1_Linux_JETSON_AGX_THOR_TARGETS/Linux_for_Tegra/source

./source_sync.sh -k -o

I once cd into a git pull from nv-tegra and it was empty. so to be safe I ran I think then it was jetson_36.4.3 and all the source appeared.

git checkout jetson_38.4

wpceswpces · January 19, 2026, 5:49am

Alright, whitesscott,but this part of the code in the Git repository should be public, so I feel like logging into an account shouldn’t be necessary.

wpceswpces · January 19, 2026, 5:50am

Hi，DaneLLL

Alright, thank you! I’ll try the new script you provided later.

kayccc · January 21, 2026, 12:17am

Can the new script work well?

wpceswpces · January 21, 2026, 1:42am

Hi，kayccc

Sorry, I tried the new script, but it directly exits without cloning the code from the repository.

Hi,DaneLLL

I tried the parameter without -k and found that, just like in the old script in version 7.1, the device tree can be pulled down, but the kernel source cannot. After waiting for 5 to 6 minutes, the kernel source directory is still empty except for the .git file.
