Please help to provide more information for your device, JetPack SW info, camera info, command info.
Then we can know how to support.

i am using orin-nx with jetpack 5.1.3 and using cmd “v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1000” to capture. I am using lt69uxc to capture data. I was captured full hd it works fine. But when i capture 4k it gets the problem.

Boost the clocks to try.

sudo su
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate
cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee  /sys/kernel/debug/bpmp/debug/clk/isp/rate
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
cat /sys/kernel/debug/bpmp/debug/clk/emc/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/emc/rate
