NVidia Jetson Jetpack 6 support?

Otca

Hi,
I have successfully built the drivers for downstream/i2c on the Jetson Orin NX running Jetpack 6 (r36.3). Based on my testing, it appears that the issue is likely related to v4l2 in the upstream code, or possibly the tegra-camera.ko module.

Could you kindly provide me with the source code for v4l2 so I can attempt to build it myself? Alternatively, if possible, please share the pre-built .ko module.

Just to clarify, the board model I'm working with is the Jetson Orin NX, though v4l2 reports it as XAVIER 10-bit. I have also attached the relevant Dmesg log for your reference.

Additionally, I’ve tried both the prebuilt .ko file from your Git repository and my own built version, but both resulted in the same issue. This suggests that the problem isn’t related to the downstream/i2c modules.

Thanks in advance for your support!

Based on your suggestion, I believe the driver is fine. Please try the following command to see if it can receive data properly.

export WIDTH=2432
export HEIGHT=2056
export FPS=28
v4l2-ctl --set-ctrl roi_x=0
v4l2-ctl --set-ctrl roi_y=0
v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY
v4l2-ctl --set-ctrl frame_rate=$FPS
v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null

If there are no issues, please refer to the link below and try capturing images using qV4l2 and a Python script. I remember that VLC had some problems with JetPack version 6.

@otca Please check the version of camera.

https://wiki.veye.cc/index.php/Mv_mipi_i2c.sh_user_guide#version

sudo ./mv_mipi_i2c.sh -r -f version -b 10

Otca

@veye_xumm said in NVidia Jetson Jetpack 6 support?:

sudo ./mv_mipi_i2c.sh -r -f version -b 10

sure!

sudo ./mv_mipi_i2c.sh -r -f version -b 10

version is C 01.41 and L 02.06

veye_xumm

@otca
The version is OK. Have you set the camera's operating mode? Please try this command:

sudo ./mv_mipi_i2c.sh -r -f trgmode -b 10

I did encounter images not being received properly due to compromised mipi signal quality caused by third party carrier board, but your board is supposed to be an official nvidia board, right?

Could you please try connecting the camera to another csi port?

Otca

@veye_xumm said in NVidia Jetson Jetpack 6 support?:

sudo ./mv_mipi_i2c.sh -r -f trgmode -b 10

sure I will try other CSI port and my board is Jetson Orin NX DeveloperKit (16GB). It's supported by VEYE and Nvidia.

sudo ./mv_mipi_i2c.sh -r -f trgmode -b 10
r trigger mode is 0

I'll reboot and give you the result for other CSI

Otca

@veye_xumm
I am experiencing an issue with CSI number 1. Specifically, it is not functioning properly on CSI-1, while everything works fine on CSI-0.
I would appreciate it if you could provide insight into why this might be happening. Additionally, I would like to mention that the vlc component is working without any issues, so the problem seems isolated to CSI-1 in my case.

In the End, I cannot express how truly grateful I am for all the assistance you've provided over the past two weeks. Your patience and dedication throughout the entire process have been remarkable. Thanks to your consistent help, everything is finally working perfectly, and I am incredibly appreciative of your efforts.

Once again, thank you so much for your unwavering support and understanding.

veye_xumm

@otca You are welcome.
I just tested it on my side with the Orin NX 8G version (P3767-0001), and both camera channels are working fine.
This issue is a bit strange.
Do you have any other cameras? Could you check if the cam1 on your board is functioning properly?

Otca

@veye_xumm Sure, I'll Check it.
would mind helping me for getting Max FPS please?

According to Veye Wiki, I can get 67 frames per second.

Would you please tell me what should I do in addition to get the highest FPS?

Ok, I have the same mvcam imx296m with adp-mv1 adapter connected to Orin nx 16GB board from seeed studio.

I used overlay dtbo loading method. The ‘sudo insmod veye_mvcam.ko’ ran w/o error returning.
But I got these errors checking ‘dmesg| grep -i mvcam’:

What could be the reason? I tried both local build .ko and downloaded (latest version) .ko files. Same symptom.

My system is R36.3 Jetpack 6.0.

BTW, where does the tegra_camera.ko come from? I seem do not find place to compile it. Thanks.

vitob

Also, besides the tegra-camera.ko question, I noticed the v4l2-core/*.ko also different between nvidia_jetson_veye_bsp release tar ball and default *.ko in /lib/modules/$(uname -r)/kernel/drivers/media/v4l2-core/. How are these *.ko files are compiled in nvidia_jetson_veye_bsp.tar.gz and where are the source files?

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

veye_xumm

@vitob
I think the first thing you need to check is whether this baseboard from seed is compatible with the official nVidia carrier board and whether it uses the same dtb？

@veye_xumm , let me confirm this, although I used sdkmanager to flash the board with nvidia native packages w/o issues.

@vitob said in NVidia Jetson Jetpack 6 support?:

tegra-camera.ko question, I noticed the v4l2-core/*.ko

In the meantime, can you help explain this question on tegra-camera.ko and v4l2-core/*.ko? Why they needs to be updated and where can I find the source code of them? Once updating them using the veye release .ko, will that affect other cameras (for example, I want to port/develop driver for another sensor myself)? Thanks.

Please use -b 9 or -b 10 as an argument.

These driver changes add support for RAW8 RAW10 RAW12 data types on the one hand, and externally triggered modes on the other.
