Jetson Orin NX (JetPack 6.2 / L4T R36.4.3) – source_sync.sh fails with nv-tegra connection error

[shreya2002n]

Hello,
I’m working with the Jetson Orin NX and JetPack 6.2 (L4T R36.4.3), and I’m trying to download kernel and device tree sources using the provided source_sync.sh script.

Here’s the command I ran:
./source_sync.sh -k tegra-l4t-r36.4.3

But it fails for all repositories with the following error:
fatal: unable to connect to nv-tegra.nvidia.com: Connection refused

1. Is there an alternate way to fetch the kernel and device tree sources for R36.4.3?
2. Is nv-tegra.nvidia.com deprecated or region-restricted?

Thanks in advance!

When reference is changed from git:// to http:// in source_sync.sh:
fatal: unable to access ‘http://nv-tegra.nvidia.com/3rdparty/canonical/linux-jammy.git/’: Failed to connect to nv-tegra.nvidia.com port 80 after 216456 ms: Connection timed out

./source_sync.sh -k tegra-l4t-r36.4.3

Here release tag is wrong. Refer release notes pdf for correct release tag.
