IMX412 flashes bright and dark in low light

It looks like the gain command is overflowing at high gain and causing the gain to occulate between high and low values.

Hello @sb3d-tech-mteitel ,

sorry for the late reply.

May I ask you for your setup?

Nano/Xavier (Orin/Non-Orin) L4T version?
2 or 4 lanes?
Are you streaming via v4l or nvargus?
When streaming via ISP, is the auto-exposure set? Do you have a camera_overrides.isp file applied?
If ae-lock is set with ISP or streaming with v4l, which exposure values are set?
What is the resolution you are running on? Any roi-cropping values set?
When setting the gain value, which value do you set and what is

dmesg -w

reporting according to your applied value?

What is your sensor revision?

Maybe you can provide one or two images to demonstrate this effect.

best regards
