I’ve been stuck on a capture issue with Jetson AGX Orin (kernel 5.10.120, Ubuntu) and LT6911UXE HDMI-to-MIPI CSI-2 bridge for a long time. I hope someone can help me out.
Platform: NVIDIA Jetson AGX Orin
Kernel: 5.10.120
Chip: LT6911UXE (I2C addr 30-002b)
Devices: /dev/video0, /dev/media0
From media-ctl -p -d /dev/media0:
All links are ENABLED
Path: lt6911uxe 30-002b → nvcsi@15a00000 → vi-output /dev/video0
From v4l2-ctl --list-formats-ext:
1920x1080@60fps
Formats: UYVY, NV16
Everything seems enumerated correctly.
Command:

v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --stream-mmap=3 --stream-count=1 --stream-to=out.raw

It seems the problem is not the I2C communication or driver probe ,
I can
successfully read and write LT6911UXE registers via I2C (I2C address 0x2b).The chip probe is OK, and all register values are normal.But I still get the
VI capture timeout and
VI channel not found error when capturing.
Hello @ChenYann ,
Can you share your Device Tree node configuration?
The VI channel not found error sounds like it could be associated to a bad device tree configuration.
best,
We fix real NVIDIA Jetson issues: Board bringup, driver development, CUDA errors, flashing failures, containers, and performance bottlenecks. Hands-on engineering support for teams shipping hardware.

Sure, these are my device tree related files. Thank you.i2c@3180000 node in the tegra234-p3737-camera-modules.dtsi file.

Get the trace log to analysis.
Thanks
I captured the log using sudo dmesg and saw the error:csi5_stream_close: Error in closing stream_id=0, csi_port=0
How can I capture trace logs? Are there any recommended commands?
Get the trace log by below command.
modprobe rtcpu_debug

echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb

echo > /sys/kernel/debug/tracing/trace
v4l2-ctl --stream-mmap -c bypass_mode=0
cat /sys/kernel/debug/tracing/trace
I have run the command mentioned above.

Thank you for your reply.
The trace log shows doesn’t receive any data from the sensor.
You may need to probe the output signal.
Is this related to the channel configuration? For example, if CSI port channel 0 was mistakenly used as channel 1, or if there was an error in the VI port configuration.
I can’t tell, you need to confirm the port-index/bus-width with your HW connection.
Thanks
We are using 2 lanes, and we have tested the wiring; no connection issues were found.

You should remove the “lane_polarity = 6;“ for AGX Orin.
This property only for Orin NX/Nano
Thanks
I made the following changes: deleted lane_polarity = [36 00];, changed tegra_sinterface = "serial_b"; to tegra_sinterface = "serial_a";, yet the result was the same as before.

If your port-index/bus-width match to your HW design you real need to check the HW due NVCSI/VI don’t receive any data from the MIPI bus.
For the device tree of lt6911uxe, I referred to the tegra234-camera-p3785.dtsi file.
I replaced the imx219 device with the lt6911uxe at the corresponding position, re-edited the device tree, and kept the same CSI ports and VI ports configurations.
The nvgstcapture-1.0 command can capture images normally, so I believe there is no issue with the hardware link.
After switching back to the lt6911uxe device, the video0 device can still be detected, but the nvgstcapture-1.0 command does not work.
Are there any other available commands?
thanks
Do you mean nvgstcapture-1.0 can see the preview with lt6911uxe?
I don’t think nvgstcaptrue-1.0 able to support YUV format sensor.
1、The IMX219 camera module can display images normally using the nvgstcapture-1.0 tool.
2、The LT6911 video bridge chip fails to display any images when using nvgstcapture-1.0.
3、When executing the command v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --stream-mmap=3 --stream-count=1 --stream-to=out.raw for the LT6911, the following errors are shown in the output of sudo dmesg.
This error tell unable capture frame data from the sensor and timeout.
Also the trace log shows doesn’t receive any data.
Please probe LT6911 output signal to make sure the output follow the MIPI spec.
Thanks
