Hi Community:
I use MAX9296+MAX96705+ov01f10 in R34.1.1 with orin. My camera output format is YUV422 8bit.
I have done my drivers(even MAX9296 driver, I did’t use the driver by nvidia) and try to capture with command with command:

gst-launch-1.0 v4l2src ! video/x-raw,width=1280,height=720,format=YUY2 ! videoconvert ! video/x-raw,format=I420 ! xvimagesink sync=0

and I got this :

I tried to get yuv frame by:

v4l2-ctl -V --set-fmt-video=width=1280,height=720 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=5 --stream-to=2M_yuyv_dtsi_video.yuv -d /dev/video0

then got kernel error:

My camera and ser/deser have tested on another platform, they work fine, so registers config should be OK.
I tested with v4l2:

Could someone tell me what should I check?
I have tried to modify bus-width,either 2 or 4 got the same result.
Attach is my device tree and drivers.

Have a check the pix_clk_hz to confirm if the data rate > 1.5G

Skew calibration is required if sensor or deserializer is using DPHY, and the output data rate is > 1.5Gbps.
An initiation deskew signal should be sent by sensor or deserializer to perform the skew calibration. If the deskew signals is not sent, the receiver will stall, and the capture will time out.
You can calculate the output data rate with the following equation:

Output data rate = (sensor or deserializer pixel clock in hertz) * (bits per pixel) / (number of CSI lanes)

Hi ShaneCCC:
Thanks for your reply. My deserializer output date rate is 300Mbps.

6

What’s the pix_clk_hz in your device tree?

7

Hi ShangCCC:
My camera output YUV422 8bit, and the image size is 1340x1020@30fps. I set MAX9296 csi registers for 1x4, 300M. So my devicetree is below:

pix_clk_hz = "42000000";
serdes_pix_clk_hz = "75000000";

Please get the trace log if more clue for it.

Hi ShaneCCC:
I changed the “frame line” in my sensor driver, then I run got recieve err like this:

The trace log tell the err_intr_stat_ph_ecc_multi_bit_err
It could be the MAX9296 configure cause the problem.

Hi ShaneCCC:
I followed your advice to modify ser/deser register, now I can capture camera data. But I got framerate problem.
My camera output is 1280*720@30fps, but in fact, I guess it’s 10fps or less. Because the monitor screen stutters when I move camera. I tired to modify framerate in device tree and sensor driver, but no improve.
When I run gst-launch like below:

gst-launch-1.0 v4l2src ! video/x-raw,width=1280,height=720,format=YUY2 ! videoconvert ! video/x-raw,format=I420 ! xvimagesink sync=0

I got log like this:

The CSIMUX_STREAM from the trace log tell the SPURIOUS data. That could be the MAX9296 output some user define data cause it.

Please check the frame rate by v4l2-ctl .

v4l2-ctl --set-fmt-video=width=1280,height=720, --set-ctrl bypass_mode=0 --stream-mmap -c frame_rate=30

Hi ShaneCCC:
I run the v4l2-ctl and get the same error message like below:

wanji@orin:~$ v4l2-ctl --set-fmt-video=width=1280,height=720, --set-ctrl bypass_mode=0 --stream-mmap -c frame_rate=30

OK, suppose need to fix the CSI_MUX_STREAM for it.
Please consult with vendor if any user define data output to disable it to verify.

Hi ShaneCCC:
Thanks for your help, finally I found the problem is VS polarity settings in MAX96705.
I inverted the VS signal by set MAX96705’s register 0x40 to 0x2F, then I can get the normal 30 fps stream.
