Dear NV_Team,

I implement a gmsl camera using ov2778/max9295+max9296, open camera failed with csi error.
Can you help to check the CSI error log?

Below error tell the output size less than expected.

tag:CHANSEL_SHORT_FRAME

Hi ShaneCCC,

tag:CHANSEL_SHORT_FRAME means “sensor output size less than expected.”
but
tag:CSIMUX_STREAM indicate SPURIOUS_DATA_STREAM_2 means “Spurious data means VI sees some other packets before FS packet, as VI alwasy expect the 1st packet to be frame start” right?

Thanks.

[ShaneCCC]

Yes, that’s correct.

Okay, thanks, we will check the parameter settings again.
