CSI0 is OK,CSI2 no stream

I use custom board and TX2 NX module. There are some NVP6188 AHD to MIPI chips. CSI0 is streaming ok, but CSI2 no stream output. This is pin usage , error information and device topology. I have no idea how to solve it. Thanks a lot.

The trace log show the SPURIOUS_DATA_STREAM.
Spurious data means VI sees some other packets before FS packet, as VI alwasy expect the 1st packet to be frame start

What may be causing this? Is my device topology binding right? CSI A → CSI0 ->port index 0 bandwidth 2. CSI C ->CSI 2 ->port index 2 bandwidth. CSI1 not used.

I solve it , MIPI signal has some problem, I fix the AD driver. Thank you.
