Argus camera always launches with max exposure time

Hello! I have noticed a weird trend with nvargus - when I start up my camera, it always starts up with the maximum exposure time.

For example, my max exposure time is 5 seconds, when I start up the camera, it takes 5 seconds to get the first frame, then the next frame is like 4 seconds and it gets lower and lower until ISP sets normal exposure time. So basically from Argus launch until proper preview it takes like 15 seconds.

What could be the issue here?

What’s kind of sensor support 5 seconds? How do you check the exposure time?
I think it could be the sensor driver initial REG table set 5 seconds as default. Have a check some others sensor to confirm it.
