Controlling IR-Cut filter

[Venkata Subbarao]

I have a Chinese IP camera with Hi3516D+OV4689 solution. I could load my own kernel and rootfs and run the sample programs that came with HiSilicon SDK. The video is pinkish during day time because of the IR-Cut is not on. Sometimes, it looks clean and sometimes pinkish. Looks like programmatically we need to set the IR-Cut. Any idea how to do ?

Thanks

My guess is it will be via one of the GPIO pins.
As to which - this will depend entirely on the specific board design.
You may get some clues if you try reversing the main app from the native firmware, if you have it.
