How to use an older kernel on Jetson Xavier NX

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

I have an Jetson Xavier NX developer kit, and a Magewell Eco Capture HDMI 4K M.2 Card.
https://www.magewell.com/downloads/eco-capture#/recent
From the release notes of the Eco Capture Linux x86 Driver V1.4.89 - “Fix problem: driver installation may fail on an operating system with kernel version 5.8 or above.”

I followed the standard tutorial for the setup of the Jetson Xavier NX, which uses kernel version 5.10.65-tegra.

I attempted to install the driver, but it failed to build module because my kernel version is not supported by the Magewell installer.

I could not find any archived SD card images from Nvidia with older kernel versions, is there somewhere I can find one to reflash? Otherwise, how can I downgrade my kernel version?

I don’t understand your reason to downgrade kernel. That driver says it supports >= 5.8 kernel.

Hi Wayne,

Clicking release notes it says “Fix problem: driver installation may fail on an operating system with kernel version 5.8 or above.”

Oh ok. Then how about you just use rel-32 release for NX?

Magewell support was able to solve the issue. They sent me the beta driver for the TX2:

This worked for me on the Jetson Xavier NX with kernel version 5.10.65-tegra and my Magewell device is now working properly now to capture HDMI input.
