IMX477 Arducam Configuring the Jetson Expansion Headers

Sunim_1 · May 12, 2025, 10:32am

I am using Jetson XaviernNX emmc module SOM and I connected IMX477 Camera with the som. Whenever I use camera with the newly flashed som. Camera is not detected under ls /dev/video*

Error:
ls /dev/video*
ls: cannot access ‘/dev/video*’: No such file or directory

Using the below approach, it works:

sudo /opt/nvidia/jetson-io/jetson-io.py

ls /dev/video*
/dev/video0 /dev/video1

Is their any way so that I need not to configure the IMX477 MIPI Camera each time after flash.

Kindly help to resolve this and share the device tree overlay path where I need to make anychanges required.

I have done the following changes inside the dtb and try to reflash but still camera not detected under ls /dev/video*

devicetree.txt (11.3 KB)

Thanks…

Hello @Sunim_1

Do you know how to compile the kernel and device tree and flash the binaries compiled into the board?

If so, you can modify the kernel-5.10/arch/arm64/configs/tegra_defconfig from the kernel sources to set the IMX477 driver as a build-in driver as:

CONFIG_NV_VIDEO_IMX219=n
CONFIG_NV_VIDEO_IMX477=y

Compile all the binaries and flash them into the board.

I hope this helps.

After flash you need to run the jetson-io to enable IMX477.

Sunim_1 · May 16, 2025, 9:23am

So, you mean to say doing this will resolve my problem of reconfiguring after flash?

CONFIG_NV_VIDEO_IMX219=m
CONFIG_NV_VIDEO_IMX477=m
CONFIG_NV_VIDEO_IMX268=m
CONFIG_NV_VIDEO_IMX274=m

IMX477 should be default enable. You just need to run the jetson-io to enable it after flash.

Sunim_1 · May 19, 2025, 5:02am

What does it mean “default enable” and need to run “jetson-io to enable” after flash ?

ShaneCCC · May 19, 2025, 9:15am

Kernel config is default enable but device tree need jetson-io to enable it by overlay.

Sunim_1 · May 28, 2025, 12:11pm

@ShaneCCC @EduardoSalazar96 That’s what I dont want to enable everytime after flash using Jetson-IO Tool.

ShaneCCC · May 29, 2025, 2:38am

You can back up the dtb and extlinux.conf and restore it after flash .

I am using Jetpack versoin 5.1.5. I could not found overlay file for IMX477 in /boot/dtb.

Do I need to create an Overlay file for IMX477 ?

ShaneCCC · May 29, 2025, 1:14pm

Should in the /boot

nvidia@nvidia-desktop:/boot$ ls /boot/ | grep -i imx

Do I go with this: tegra194-p3668-all-p3509-0000-camera-imx477-dual.dtbo

And after that I need to apply the overlay and add imx477 entry in the extlinux.conf file ?

ShaneCCC · June 2, 2025, 4:23am

You can save kernel_tegra234-p3768-0000+p3767-0005-nv-super.dtb and tegra234-p3767-camera-p3768-imx219-dual.dtbo
for example and extlinux.conf to restore to new flash system to enable it.

You have to modify the DEFAULT to imx477 instead of primary.

Does this look good:

I tried to make IMX477 Default and after reboot the SOM, no video devices detected under ls /dev/video*
Are there kernel modules or dtb changes required to detect IMX477 correctly?

I feel IMX477 Overlay does not applied fully.

kayccc · June 18, 2025, 3:53am

Is this still an issue to support? Any result can be shared?

Sunim_1 · June 18, 2025, 5:15am

I try to implement the above process I shared but seems like imx477 overlay does not applied fully.
Can you help me with example extlinux.conf file need to be look like.
