I am using FRAMOS IMX335 sensor with JetsonTX2. When I use v4l2 to capture image and and configure v4l2 to use gain I get 00000000 in some of my raw data pixels. The more gain I add the more zeros I get.
I did email the framos support but they are not helpful. They want me to pay $10,000 for 10 hours of support. In my opinion something like this should be in the documentation and not require extra support
