When using the v4l2-ctrl for raw acquisition of images from any FRAMOS Module it is necessary to include to 

switch --bypass_mode=0. This will ensure the ISP is not operating and creating conflicting sensor settings This effect of not using this are un-commanded, by the user, changes in gain and exposure. 

Example command;

 v4l2-ctl -d /dev/video0 --stream-mmap --set-ctrl bypass_mode=0 --set-ctrl gain=200 --stream-skip=1 --stream-count=1 --stream-to=test.raw

Another example:

v4l2-ctl -d /dev/video0 --stream-mmap --set-ctrl bypass_mode=0 \ --set-ctrl=black_level=0,gain=1,exposure=22000 \ --stream-skip=1 --stream-count=1 --stream-to=test.raw
