Hi, guys:
I need your help.
my parterner design a max9288 board to mount on the xavier agx.

the data flow is AR0231->AP0202->max96705->max9288->xavier agx

AR0231+AP0202+max96705 is a camera module.

I modify the driver from imx390 driver in sources code L4T 32.4.

I can get the /dev/video0. but there no video.

I try to debug with the commond

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 1 > /sys/kernel/debug/tracing/events/camera_common/enable
echo > /sys/kernel/debug/tracing/trace
v4l2-ctl --stream-mmap --stream-count=10
cat /sys/kernel/debug/tracing/trace

heres some hint

the reg val of max9288 and max96705

and i’m real confuse about the param about mclk ,pix_clk_hz,serdes_pix_clk_hz?

The trace log show NVCSI/VI didn’t receive any validate data. Only the saw a PHY_INTR0 message.
It’s should be the case that you set the sensor with continous clock mode and enable sensor streaming before enable NVCSI, but the discontinuous_clk was no in the dts.

well thank you for your reply.
but I am really confuse about how the modify the driver. please say more. thank you very much

Confirm if the sensor is configure as continuous mode and consult with vendor to configure it as discontinuous mode to try.
