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. Environment Platform: NVIDIA Jetson AGX Orin Kernel: 5.10.120 Chip: LT6911UXE (I2C addr 30-002b) Devices: /dev/video0, /dev/med…

Do you implement the “irq” routine in your driver to register the intrrupt? For example in the probe() using the platform_get_irq()/devm_request_threaded_irq() kernel API to implement it. And you should be able to confirm by check by “cat /proc/interrupts”

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 no…

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. [image] ChenYann: The nvgstcapture-1.0 command can capture images normally

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. [Screenshot from 2026-03-05 07-01-11] 3、When executing the command v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,he…

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

I inspected the hardware interface and found no abnormalities; the MIPI wiring is functioning normally. When executing the command v4l2-ctl --device /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-to=frame.yuv --stream-count=100, t…

I found the patch 0001-Camera-fix-kernel-warning-after-VI-timeout.patch in the thread Vi_capture_request_unpin cause kernel panic - Jetson Systems / Jetson AGX Xavier - NVIDIA Developer Forums, but I’m unable to download it. Could you please share it with me?
