We get CSIMUX_STREAM error during implement gmsl driver

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.

Hi ShaneCCC,

tag:CHANSEL_SHORT_FRAME means “sensor output size less than expected.”
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?


Yes, that’s correct.

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