After loading the driver normally, use the following command to capture the frame rate:

v4l2-ctl -V -d /dev/video0 --stream-mmap

Using sudo dmesg, you can view the following log:

hello FANYX,

even though your tracing logs shows FS (frame-start)/FE (frame-end), there’s no SOF and EOF received by CHANSEL (channel select).
your cch index also looks incorrect, it should be an unsigned values but it’s shown -1 in the tracing logs.

BTW,
since you’re running with SerDes chip, is it possible to enable the TPG (test-pattern-generator) for issue narrow down?

I measured the mipi signal of max9296 terminal, and the mipi signal can be measured by 4lane, and this configuration can be normally lit on the UVC box.
