Unable to capture video from IMX219 with v4l2-ctl on Jetson Orin NX Jetpack6.1

Hi,
I am running Jetpack6.1 on Jetson Orin NX.
I have IMX219 camera connected and I am using the default tegra234-p3767-camera-p3768-imx219-C.dtbo
as an overlay.
When capturing the video using nvgstcapture everything works fine.
But when I am using v4l2-ctl with the following command:

v4l2-ctl --set-fmt-video=width=1280,height=720,pixelformat=RG10 --stream-mmap --set-ctrl=sensor_mode=4 --stream-count=100 -d /dev/video0

The program freezes and when i kill it with Ctrl+C there are some kernel crash dumps in the system log, but the system remains stable.

The the dump logs:

Is v4l2 still supported?

Thanks,

You need add -c bypass_mode=0 in the v4l2-ctl pipeline.

Thanks

Hi,
Thanks for the response
I have tried adding -c bypass_mode=0 and it looks like it solved the kernel errors, but now Im getting timeout from the VI.
Im using the following command:

v4l2-ctl --set-fmt-video=width=1280,height=720,pixelformat=RG10 --stream-mmap -c bypass_mode=0 --set-ctrl=sensor_mode=4 --stream-count=100 -d /dev/video0

I get the following errors:

[  498.646436] tegra-camrtc-capture-vi tegra-capture-vi: uncorr_err: request timed out after 2500 ms
[  498.646450] tegra-camrtc-capture-vi tegra-capture-vi: err_rec: attempting to reset the capture channel
