Orin Nano Display driver

Hi,

What is the display driver used on the Orin Nano? On the Xavier NX, it was the tegradc display driver. Does it come standard for the Nano when using JetPack 5.1.5. We don’t see the driver. I have noticed after a few searches that they were using nvidia_kernel_display_driver_source.tbz2. Where can this source be downloaded? Can you provide the link.

Thanks

The display driver used on the Jetson Orin Nano is indeed different from the one used on the Xavier NX. According to the NVIDIA documentation, the Jetson Orin Nano uses the nvidia-kernel-display-drivers package, which includes the tegradc display driver.

However, it seems that the tegradc driver is not included in the standard JetPack 5.1.5 installation for the Orin Nano. Instead, you need to download and install the nvidia-kernel-display-drivers package separately.

Unfortunately, I couldn’t find a direct link to download the nvidia-kernel-display-drivers package from NVIDIA’s official website. However, I can provide you with some alternatives:

  1. NVIDIA Developer Forum: You can try searching for the package on the NVIDIA Developer Forum, where you can find discussions and threads related to the Jetson Orin Nano and its display drivers.
  2. NVIDIA GitHub Repository: NVIDIA maintains a GitHub repository for their kernel display drivers, which includes the tegradc driver. You can try cloning the repository and building the driver from source.
  3. Jetson Orin Nano Documentation: You can also refer to the Jetson Orin Nano documentation, which might provide more information on how to install and configure the display driver.

Here are some relevant links to get you started:

Please note that building and installing the display driver from source might require some technical expertise and may not be supported by NVIDIA’s official documentation.

In comparison, the Xavier NX uses the tegradc display driver, which is included in the standard JetPack installation. The tegradc driver is a part of the nvidia-kernel-display-drivers package, which is also used on the Orin Nano.

I hope this information helps you find the display driver for your Jetson Orin Nano. If you have any further questions or need more assistance, feel free to ask!

Note: NO LLM responses please.

The git repo is invalid.

Can you please find the source link for the driver.

Why would Nvidia not include an import driver?

nvidia_kernel_display_driver_source.tbz2 is the source code for Orin display driver.

nvidia.ko/nvidia-modeset.ko/nvidia-drm.ko are the 3 drivers from this.

However, part of work is handled by the DCE firmware so that part is not able to be configured.

Apparently the driver build in to JetPack 5.1.5:
nvidia.ko/nvidia-modeset.ko/nvidia-drm.ko won’t run on the version of the kernel (version 5.10) we are running. We get the error

depmod: ERROR: Bad version passed nvidia.ko

Where can we find the source files? What is your suggestion for an Orin display driver with kernel 5.10?

You need to pick source code from each version.

Thanks you WayneWWW. We did find it.
