Jetson Linu R35.4.1 Cuda 12.5

[marius.westgaard]

Hi,

We are currently running our devices on Jetson Linux R35.4.1 JetPack 5.1.2 and wanted to upgrade cuda through the cuda update path described here: CUDA for Tegra

We are however using Yocto and the meta-tegra project to build and deploy our stack.

We have gotten cuda 12.5 on the device, and we can successfully run the deviceQuery app from the cuda-samples package that confirms that cuda 12.5 works.

However according to chapter 6.2.1 JetPack 5 only supports cuda upgrades up to cuda 12.2.

Why is not higher cuda versions supported?
What is potentially breaking by running cuda 12.5?

Hi,

A newer CUDA 12 version is available with the JetPack 6 environment.
Since JetPack is Ubuntu22.04, the package cannot be installed on JetPack 5 which is Ubuntu 20.04.

Thanks.

Hi AastaLLL,

As I said we are using Yocto and meta-tegra to build and deploy, so we are basically bypassing Ubuntu.

Why exactly can the newer cuda 12 versions not be installed on Ubuntu 20.04?

Hi,

We switch to Ubuntu 22.04 after CUDA 12.4.
If the Ubuntu version doesn’t matter in your environment, you can try it.

The table is for the official environment so the package built for Ubuntu 22.04 cannot be installed in JetPack 5 environment.

Thanks.
