iMX6 - How to connect GRAY16 format input through CSI

[cankanbak]

Hello,

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.

Hi Can,

unable to open /dev/video0 means you have not video at all in channel 0, looks for another channel, the ipu can not be changed to get GRAY16_BE but you must open with gstreamer.
