hi ，all
We need to use NX core board to develop a system with one camera，we use a HDMI2MIPI chip(lt6911uxc) that output mipi-cs2 signal. camera connects CSI0 with 2 lane.
our L4T version is 32.6.1. I find in BSP source has a LT6911UXC driver,( Linux_for_Tegra/source/public/kernel/nvidia/drivers/media/i2c/lt6911uxc.c ),so I modify DTS(tegra194-camera-e2832.dtsi),
now when I use command “v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RGB --set-ctrl bypass_mode=0 --stream-mmap=3 --stream-count=100” to capture vidio ,system
report error "tegra194-vi5 15c10000.vi: vi_capture_setup: control failed, errno 2
[40394.029770] tegra194-vi5 15c10000.vi: vi capture setup failed "
I find errno 2 in capture.c ,so What does this error represent and how to check it?
Get the trace log to check if can get more clue.
v4l2-ctl --all

The trace log show didn’t receive any validate data from MIPI bus.
Did you probe the signal to confirm it?
I can’t tell if the DTS is correctly or not. You need check with your HW connection to confirm the port-index/bus-width
Yes, that’s correct. Maybe need to confirm the output signal follow MIPI spec.
@ShaneCCC we checkout mipi signal，its ok，so why we dont capture any MIPI signal？HDMI input is 1080P/30f，Are the configurations in the red boxes of our DTS correct？
num_lanes is correct and pix_clk_hz should doesn’t matter
Have a check this document for detail information.
