iMX6 - How to connect GRAY16 format input through CSI

Question asked by Can Kanbak on Jun 5, 2018

I have a TinyRex iMX6QP module and I want to capture video coming from an FPGA in 16bit grayscale format. The TinyRex module works fine when a YUV video is given through the HDMI input on the TinyRex baseboard, but when used with a custom board to get the 16-bit grayscale video, neither the gstreamer pipeline, nor the mxc_4l2_capture tests work, and both give errors stating "Unable to open /dev/video0". Does this mean the devices or their drivers are unable to start, or is there another problem? Should the IPU driver be changed to be able get GRAY16_BE format and is there any patches for doing this?


Any help is appreciated, thank you.
