Jetson Nano/Xavier NX: Configuring the CSI connector w/ jetson-io

If your Nvidia Jetson Nano and Xavier NX boards are running L4T R32.6.1 or later versions, you can configure the CSI interface with jetson-io.

To check the L4T version, run the following command.

Pro Tips

Using a pre-configured SD Card image with a different version of Nano (A02/B01) or NX will not work.

However, if you insist on using the same SD card with other Jetson boards, here’s the fix:

Method 1. Uninstall the Arducam driver, and reinstall it with the new Jetson board:

sudo dpkg -r arducam-nvidia-l4t-kernel

Method 2. Modify the /boot/extlinux/extlinux.conf file by changing the second line from DEFAULT JetsonIO to DEFAULT primary.

Before:

After:

Save the changes and reboot the system, then use jetson-io to reconfigure the CSI connector for the new board.
