I have Leopard Imagining set of Jetson TX2 and IMX390 cameras. I am fiddling a little with the driver. The sensor itself can set analog gain in range 0…30 dB with 0.3 step and digital gain 0…42 dB with 0.3 step. I want to utilize it in full, so I would like to set gain in range 0…72 dB.
I have changed the tegra186-camera-imx390-a00.dtsi file, adjusted config of the sensor and code of the driver. Unfortunatelly in argus_camera I still get Gain range 1.122 … 31.623. I can set value outside this range via v4l2-ctl.
What should I change in order to be able to set gain in range 0…72 dB via ARGUS API?
