I decided to return the camera sensor and look for a better alternative despite my best efforts

D_101

@veye_xumm So I've taken the following steps

Re-flashed my Orin with the NVIDIA SDK manager
Changed the CSI cable with the second cable that was provided by you guys. I also ensured the black tab on the Jetson Orin was facing 'up' while the pins on the wider end of the CSI cable that went to the IMX462 was facing 'towards' the tab (Please see pictures below for reference)

And below are the steps that I took that eventually lead to the same probing error that was mentioned earlier

After restarting the Orin, I got the following dmesg output

I did my best to be as thorough as possible, but at this point I'm not sure what else I could be missing

@veye_xumm said in Jetson Nano Orin IMX462:

@d_101

I think your hardware connections are correct. Also, the Dupont wires are generally not required.

I believe there are some issues with your operations on the .ko and .dtb files. Let me explain in detail below:
Your camera model is VEYE-MIPI-IMX462, which is a color camera. You should only use the veyecam2m-labeled DTBO and veyecam.ko. There is no need to update the .ko files in the downstream and upstream directories.

However, judging from the dmesg output, it seems that you have also performed some correct steps, because the command dmesg | grep veye shows that the driver has been loaded correctly and has attempted to probe the camera.

Overall, I think there are some minor issues in your operations, but the general approach seems to be correct. Based on the following information:
# Checking dmesg
[   10.758731] veyecam 9-003b: probing v4l2 sensor
[   10.758853] veyecam 9-003b: tegracam sensor driver: veyecam_v2.0.6

[   10.771489] veyecam 9-003b: board setup failed

[   10.787671] veyecam 10-003b: probe failed
[   10.787678] veyecam 10-003b: board setup failed
I can only suspect a hardware issue. Please remove the Dupont wires, or try using a different MIPI port.

Responding to " You should only use the veyecam2m-labeled DTBO" I see the following in the dtbs directory

My question is

The only .dtbo file that looks right is the /tegra234-p3767-camera-p3768-veyecam2m-dual.dtbo which I did add to my extlinux.conf file as stated below

My question here is

Last listed in the directory above I only see tegra234-p3767-camera-p3768-veyecam2m-dual.dtbo and tegra234-camera-rbpcv3-veyecam2m.dtsi that come close to what you instructed earlier regarding me using the veyecam2m that was labeled with DTBO
Since I only have one IMX462 and you instructed me to
The only veyecam2m-labeled DTBO file that I assumed I need to use tegra234-p3767-camera-p3768-veyecam2m-dual.dtbo

Is that correct?

Also, responding to the comment you made earlier regarding updating the .ko files up/downstream

There is no need to update the `.ko` files in the **downstream** and **upstream** directories.

It is stated in the wiki page to do just that

Therefore, for Jetpack 6.2.1, the following commands should be modified as:

sudo cp nvidia_jetson_veye_bsp/ko/5.15.148-tegra-l4t36.4.4/downstream/i2c/* /lib/modules/$(uname -r)/updates/drivers/media/i2c/ -f

sudo cp nvidia_jetson_veye_bsp/ko/5.15.148-tegra-l4t36.4.4/downstream/terga-camera/tegra-camera.ko /lib/modules/$(uname -r)/updates/drivers/media/platform/tegra/camera -f

sudo cp nvidia_jetson_veye_bsp/ko/5.15.148-tegra-l4t36.4.4/upstream/*.ko /lib/modules/$(uname -r)/kernel/drivers/media/v4l2-core/ -f

If those steps aren't necessary for someone who's running Jetpack 6.2.1 I feel like it should be removed to lessen the confusion since the wiki page instructions aren't the easiest to follow in my opinion.

In short, I have a Jetson Orin Nano and a IMX462, despite the way I orientate the camera cable, my Orin Nano can not detect the IMX462 despite having the drivers properly installed

Below are the specifications of my Orin Nano

cat /etc/nv_tegra_release

As a sanity check, I've double/triple checked the orientation of the camera cables to my Jetson, the camera pins to the board are facing DOWN, while to the IMX462 the pins are facing UP
