R35.3.1 AGX orin bring up ar0820 raw sensor,and capture frame will get stuck

[mingming]

hi:
i bring up the sensor ar0820,and then execute this command
“v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100”, Polling execution 100 times，will get stuck。
upload the log。

Hi,

Ca you please enable the V4L2 debug trace and share the information?
You can enable trace to debug the capture process by running the following commands:

sudo su
echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
exit

The trace will give information about VI/CSI.

In order to read the output messages, run:
sudo cat /sys/kernel/debug/tracing/trace

Does your sensor connect with gmsl or ser/deser chip.
Looks like the output frame have include virtual channel ID =1 cause the problem.

hi:
we use ser/deser chip, max9295 and max9296.
Looks like the output frame have include virtual channel ID =1 cause the problem.---->How can this problem be fixed。
thanks。
