Hardware Setup

IMX477 PTZ connection.jpg

Please note that in this illustrator, the different colors of the jumper wires are just to make it easier to distinguish them from each other. The order of those colors varies from item to item, so it may not match the one you’ve received. Therefore, instead of its color, you should rely on the position of the wire to correctly connect the jumpers.

Manual driver installation for L4T32.4.3 before versions

1. Identify Kernel Number

Different kernel versions require different driver packages. You need a matching driver package for your camera to work.

To identify your kernel:

  1. Print your Kernel Version with the following command.
uname -a

Example output:

Linux jetson-desktop 4.9.140-tegra #3 SMP PREEMPT Thu Jul 16 13:41:48 CST 2020 aarch64 aarch64 aarch64 GNU/Linux

4.9.140 is our desired value.

  1. Print your L4T release number with the following command.
cat /etc/nv_tegra_release

Example output:

# R32 (release), REVISION: 4.3, GCID: 21589087, BOARD: t210ref, EABI: aarch64, DATE: Fri Jun 26 04:38:25 UTC 2020

R32 and 4.3 are our desired value.

  1. Combine the desired printed results to get the kernel detail.

From the example above, we get kernel 4.9.140 L4T-32.4.3.

2. Download Driver Package

To download Arducam IMX477 driver package:

  1. Go to Arducam GitHub repository for IMX477 on Jetson with the following URL:

What if I can’t find a matching driver?

If you can’t find a driver package matching your kernel version, please contact Arducam to update that.

  1. Enter the folder for your target Jetson board.
Jetson nano xavier nx camera driver folder

There are separate driver folders for Jetson Nano and Jetson Xavier NX, so use whichever match your target board.

  1. Click on the name of the matching driver package.
