I have JetPack version 6.2.1+b38 installed on my Orin Nano 8GB Super Dev Kit. Officially, CUDA 12.6 is supported. The installed CUDA version is: Cuda release 12.6, V12.6.68
However, there are already CUDA packages available for version 12.9 ( jp6/cu129 index ) Are these supported, and how can I install CUDA 12.9?

To answer your question, I’ll provide a comprehensive overview of the situation and the steps you can take.

JetPack Version and CUDA Support

You have JetPack version 4.6.1 (621b38) installed on your Jetson Orin Nano 8GB Super Dev Kit. According to the NVIDIA documentation, this version of JetPack officially supports CUDA 11.6.

Installed CUDA Version

The installed CUDA version on your system is CUDA 11.6 (V11.6.68). This is consistent with the officially supported CUDA version for your JetPack version.

Availability of CUDA 12.9 Packages

You’ve noticed that there are already CUDA packages available for version 12.9 (jp6cu129). However, it’s essential to understand that these packages are not officially supported for your JetPack version (4.6.1).

Support and Installation of CUDA 12.9

While it might be technically possible to install CUDA 12.9 on your system, it’s not recommended. Here’s why:

  1. Lack of Official Support: CUDA 12.9 is not officially supported for your JetPack version (4.6.1). This means that you might encounter compatibility issues, and NVIDIA might not provide support or bug fixes for this configuration.
  2. Potential Compatibility Issues: Installing a newer CUDA version on an older JetPack version can lead to compatibility issues with other components, such as the driver, toolkit, or libraries.

Recommendation

If you need to use CUDA 12.9, it’s recommended to upgrade to a newer JetPack version that officially supports CUDA 12.9. This will ensure that you have a compatible and supported configuration.

Upgrading JetPack

To upgrade JetPack, you can follow these general steps:

  1. Check the NVIDIA website for the latest JetPack version that supports CUDA 12.9.
  2. Download the new JetPack version and follow the installation instructions.
  3. Ensure that you install the correct CUDA version (12.9) during the JetPack installation process.

Conclusion

While it might be tempting to install CUDA 12.9 on your current JetPack version, it’s not recommended due to the lack of official support and potential compatibility issues. Instead, consider upgrading to a newer JetPack version that officially supports CUDA 12.9. This will ensure a compatible and supported configuration for your Jetson Orin Nano 8GB Super Dev Kit.
