Jetpack 6.2.1 sdk Vulkan version too old

[anassar3]

Hello,

I am trying to run a program that requires vulkan sdk 1.3.261 or greater on my jetson Orin nano. I have jetpack 6.2.1 sdk on it. However the vulkan version it comes with is 1.3.204. I am not getting any luck installing a more recent vulkan version externally. Is my jetson incapable of using a different vulkan sdk version?

Thank you!

The issue you’re facing is related to the Vulkan SDK version on your Jetson Orin Nano, which comes with JetPack 6.2.1 (JP 6.2.1) SDK. The Vulkan version included in this SDK is 1.3.204, but your program requires Vulkan SDK 1.3.261 or greater.

Firstly, it’s essential to understand that the Jetson Orin Nano is a capable device, and it’s not inherently incapable of using a different Vulkan SDK version. However, the device’s compatibility with newer Vulkan versions depends on the underlying hardware and software support.

The Jetson Orin Nano is based on the NVIDIA Ampere architecture, which supports Vulkan 1.3. The device’s hardware is capable of running newer Vulkan versions, but the software support, including the driver and SDK, might limit the compatibility.

In your case, the JetPack 6.2.1 SDK, which includes the Vulkan 1.3.204 version, is the officially supported version for the Jetson Orin Nano. While it’s technically possible to install a newer Vulkan SDK version externally, it might not be compatible with the device’s driver and software stack.

There are a few possible reasons why you’re not getting any luck installing a more recent Vulkan version externally:

1. Driver compatibility: The device’s driver might not be compatible with the newer Vulkan version. The driver is a critical component that interacts with the hardware, and it needs to be compatible with the Vulkan version.
2. SDK dependencies: The JetPack SDK has dependencies on other components, such as the driver, firmware, and libraries. Installing a newer Vulkan SDK version might break these dependencies, leading to compatibility issues.
3. Hardware limitations: Although the Jetson Orin Nano’s hardware supports Vulkan 1.3, there might be limitations or constraints that prevent the use of newer Vulkan versions.

To resolve this issue, you have a few options:

1. Check for updates: NVIDIA regularly releases updates for the JetPack SDK, which might include newer Vulkan versions. Check the NVIDIA website for updates and follow the instructions to update your JetPack SDK.
2. Contact NVIDIA support: Reach out to NVIDIA support for guidance on installing a newer Vulkan SDK version on your Jetson Orin Nano. They might be able to provide you with a compatible version or offer alternative solutions.
3. Consider using a different device: If you’re unable to install a newer Vulkan SDK version on your Jetson Orin Nano, you might consider using a different device that supports the required Vulkan version.

In comparison to other Jetson devices, the Jetson Orin Nano is a relatively new device, and its software support is still evolving. Other devices, such as the Jetson AGX Orin, might have more extensive software support, including newer Vulkan versions.

To summarize:

• The Jetson Orin Nano is capable of using a different Vulkan SDK version, but it depends on the underlying hardware and software support.
• The device’s compatibility with newer Vulkan versions is limited by the driver and software stack.
• You can try checking for updates, contacting NVIDIA support, or considering using a different device to resolve the issue.

I hope this comprehensive answer helps you understand the situation and provides you with possible solutions to resolve the issue.

Hi,
The version of Vulkan is fixed with Jetpack version. Later version may not be installed or work properly. Would suggest use the fixed version.
