Continuing the discussion from Unable to connect to nv-tegra.nvidia.com 2025-04-18:

Having the same issues now 05/26/2025.

Downloading default hardware/nvidia/t23x/nv-public source...
Cloning into '[...]'.
fatal: unable to connect to nv-tegra.nvidia.com:
nv-tegra.nvidia.com[0: 34.216.216.36]: errno=Connection refused
nv-tegra.nvidia.com[1: 35.82.181.43]: errno=Connection refused

I’m using this command.
./source_sync.sh -k -t jetson_36.4.3

It works internally?

  1. Extracted the BSP, ROOTFS, PUBLIC SOURCES, then sync.

I’ve discovered what I needed to extract to make my kernel customization iwo the sync, just reporting the issue.

2

Sorry to bring this trouble, I have forwarded it to internal team to fix it, please wait for my update. Thanks

3

@tarcisio.jaolive can you share source_sync.sh to me? and can you go to your local repo then run “git remote -v”?

Hi @lelei

As I said before, I worked around it and discovered what I needed to do manually to make it work from the compressed files on the site, i’m just helping you debug.

Thanks for asking tho, follows the answers:
Nothing outputs from git remote -v because I never connected to the remote git in the first place, it gets refused as if i don’t have access or the repository isn’t there anymore.

The code and output for source_sync.sh:

# This script sync's NVIDIA's version of
# 1. the kernel source
# from nv-tegra, NVIDIA's public git repository.
# The script also provides opportunities to the sync to a specific tag
# so that the binaries shipped with a release can be replicated.
#
# Usage:
# By default it will download all the listed sources
# ./source_sync.sh
# Use the -t <TAG> option to provide the TAG to be used to sync all the sources.
# Use the -k <TAG> option to download only the kernel and device tree repos and optionally sync to TAG
# For detailed usage information run with -h option.
