hello kingkong,

it looks tegra194-vi5 15c10000.vi: no reply from camera processor is reported by VI engine.

what did you mean camera is streaming, are you saying there’s high speed signaling but you cannot see camera preview frames on display side?
please share the commands you’re using. please also check Applications Using V4L2 IOCTL Directly to use V4L2 IOCTL to verify basic functionality.
thanks

Yes, the camera is streaming, I can find the signal by oscilloscope.
Test command:
v4l2-ctl --stream-mmap

Could you suggest how to debug VI engine not report?

Thanks!

hello kingkong,

please dump the formats as below…
$ v4l2-ctl -d /dev/video0 --list-formats-ext

then, please assign the sensor supported formats into v4l pipeline to test again,
for example,
$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100

it might be incorrect sensor pixel clock rate, please check developer guide for Sensor Pixel Clock session to review your pixel_clk_hz property settings.

or,
please have a try to boost all the VI/CSI/ISP clocks.
you may follow below commands to configure them.

sudo su
