jetson Orin NX platform, JetPack version is Jetson Linux 36.4 (part of JetPack 6.1), Two cameras using mipi cables directly into the jetson

The driver can be loaded and matched successfully:

However, when I enter the command for mobile phone data frames(Even when I use video1, the scenario is the same.):

v4l2-ctl -d /dev/video0 -V --set-ctrl bypass_mode=0 --stream-mmap

v4l2-ctl -d /dev/video1 -V --set-ctrl bypass_mode=0 --stream-mmap

Increasing the clock doesn’t work either; dmesg and trace remain unchanged.

Doesn’t looks like receive any validate data from the sensor.
May need to probe the signal to confirm.

Thanks

Hi ShareCCC,
已找到原因，开流寄存器写入后没有开启XMSTA start，

Thanks

Hi ShareCCC,

After I captured a frame of data, I opened it with 7yuv and found it looked like this:

root@pcai-desktop:/home/pcai/pkg_orin_nx_jp6.1_v7.3.6# v4l2-ctl --set-fmt-video=width=3864,height=2192,pixelformat=RG12 --set-ctrl bypass_mode=0 --stream-mmap --stream-skip=9 --stream-count=1 --stream-to=test.raw -d /dev/video0 -V

        Field             : None

Here is the specific log:
dmesg.txt (77.4 KB)
trace.txt (643.1 KB)

How should this be solved please?

Set the stride to 32 alignment by below command to verify.

v4l2-ctl -c preferred_stride=7744

[ShaneCCC]

If 32 alignment didn’t help try the 256 alignment.

I can't get the image properly

Set the preferred_stride to 256 alignment by below command. preferred_stride= ALIGN_UP(width*bytes_per_pixel,256) v4l2-ctl -c preferred_stride=3328

[2450732921]

Hi ShaneCCC,
I tried both of these, but neither worked。The log is the same as before.

Additionally, may I ask if it could be related to this log:

This is my format, but it seems to be different from the one here：

[ShaneCCC]

This tell the sensor output unsupported user define data.
Maybe disable it to verify.

[2450732921]

Hi ShaneCCC,

How can I modify the configuration to avoid this error? My current configuration has been posted in the above comments and description, and I’m not sure how to do this.

[ShaneCCC]

Check with sensor vendor if able to remove the sensor user define data.
