Serializer max9295+DESerializer max96712 NULL VI channel received

Autonomous Machines Jetson & Embedded Systems Jetson Orin NX

hi I am Chen Xianfei, a driving engineer from LCFC. We use serializer max9295 and deserializer max96712, but they cannot bring up properly on the Origin NX platform. We have conducted the following debugging and attached the log file.In addition, using the same deserializer and serializer on Origin AGX can bring up normally. So I used an oscilloscope to grab the origin AGX mipi csi data waveform and compare it with the mipi csi data waveform on origin nx, and also uploaded it to the attachment

Did you connect to CSI0? CSI0 D1 and CSI1 D0 P/N will always be swizzled for
P/N need add lane_polarity=6 in camera device tree.

I currently only configure one csi2 data0 as output. It seems that the waveform on csi2 data0 is present, but I still cannot obtain the data using v4l ctl

Looks like nvcsi/vi didn’t receive any validate data from sensor.
BTW, don’t just post the whole kernel log to make the review hardly if needed attached as file.

Thanks

The trace log tell didn’t receive any data from MIPI bus.

Thanks

hi ShaneCCC
Can you have any suggestions?

19

The port-index and bus-width looks like incorrect.
What the camera connect to?

Hi, xianfei.chen

It looks like there are some errors in your device tree configuration.

Your video0 are CSI0 and CSI1, but your video1 and 2 and 3 are CSI2 and CSI3, why?

And your lane_polarity is always 6, but it should only need to be configured in CSI0 and CSI1.
