IT6616 driver porting to Ubuntu 20.04

igal.kroyter · January 15, 2026, 9:35am

Hi, I try to port a non Ubutnu driver into Ubuntu env. I have modified the DT the best I could, and added the required L4T callback function. though I keep getting green screen upon Gstreamer invocation, hereafter the relevant portions of the DT and the dmesg during running the GStreamer

gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! video/x-raw,format=UYVY,width=1280,height=720 ! videoconvert ! xvimagesink

The setup is composed of a camera that provides 720p50 connected to IT6616 evaluation board and a flat MIPI cable connected to Jetson Xavier NX evaluation board Port 0.
any help will be appreciated, or you need any other information, please say so.

hello igal.kroyter,

according to the logs, it’s reporting capture has timed out, such NULL VI channel failure usually due to an invalid sensor operations.

please refer to developer guide,
you may see-also To verify the port binding result.
you should also have Applications Using V4L2 IOCTL Directly to test the basic camera functionality.

igal.kroyter · January 26, 2026, 7:45am

hi @JerryChang, I’ve converted my driver to the “tegracam framework” V2 getting the same results. how do you think I should proceed debugging the system?

JerryChang · January 26, 2026, 8:25am

hello igal.kroyter,

as mentioned, please refer to developer guide To verify the port binding result.
you may also sharing the latest device tree for reference.

hello igal.kroyter,

you may check $ gst-inspect-1.0 v4l2src, the output capabilities shows that for video/x-raw it supports YUY2, YVYU, and UYVY.
since your pixel format types as pixel_phase = "yuyv"; , you should configure the format as YUV2 in the gst pipeline.

BTW, please see-also similar forum threads for reference, Topic 288808.

igal.kroyter · January 27, 2026, 3:56pm

@JerryChang hi,

I have tried YUV2 too, same results.

JerryChang · January 28, 2026, 2:47am

hello igal.kroyter,

may I know the latest error message, do you still have NULL VI channel failure reported?

igal.kroyter · January 28, 2026, 10:50am

@JerryChang, hi,

I postpone the discussion as I’ve found that the MIPI clock was not provided correctly to the Jetson Eval board, and the levels of the signal were lower than expected as a result of incorrect impedances of the data lanes - so I wait for my HW eng, to do their “magic”. Thanks. Please do not close this discussion yet. If I have the result I’ll summarize the solution and close it.

OK so the lines were corrected and the signals seems to be stable On J12 (CAM1) on the evaluation board. here are portions of my latest DT:

hello igal.kroyter,

let me re-cap some error logs as below..

let’s have issue narrow down, please check developer guide, Applications Using V4L2 IOCTL Directly.

igal.kroyter · February 6, 2026, 6:11am

@JerryChang hi, the window was closed because after a while I closed it manually. Moreover, we ain’t using the argus. we’ve used nv_imx185.c as a reference. could you please narrow more the path to debugging?

JerryChang · February 6, 2026, 7:22am

hello igal.kroyter,

please execute with v4l2 standard IOCTL for sharing the test results.

igal.kroyter · February 9, 2026, 5:41am

@JerryChang, hi,

hope that I understood you correctly. I run the following:

hello igal.kroyter,

it looks there’s no validate frames, normally, it should be < reported below v4l pipeline to indicate a frame has saved into memory.

igal.kroyter · February 9, 2026, 6:01am

@JerryChang you are correct but I do not understand why not, all lanes and clock are connected and seems to be at the right voltage. can you suggest how to attack this challenge?

hello igal.kroyter,

do you have high speed oscilloscope? please check the MIPI signaling integrity.

igal.kroyter · February 9, 2026, 6:27am

@JerryChang , we’ve checked it, and it seems to be OK, though I must be sure that I’ve correctly “routed” the DT to the correct lanes on the evaluation board (CAM1) (J12). could you please review it? I’ve provide it above.

hello igal.kroyter,

did you have overlay dtb file applied?
please execute the commands below to dump device tree into dts formats for checking.
for instance, $ sudo dtc -I fs -O dts /sys/firmware/devicetree/base > /tmp/123.dts

current.txt (388.3 KB)
I have attached the current tree.
The way that I’ve prepared the tree was de-compiling dtb to dts. modifying the relevant sections and then compiling the full dts file to dtb and playing it in the relevant boot directory.
