The TinyRex module works fine when a YUV video is given through the HDMI input&nbsp;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&nbsp;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?</P><P></P><P>Any help is appreciated, thank you.</P></BODY></HTML> Tue, 05 Jun 2018 15:03:16 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6-How-to-connect-GRAY16-format-input-through-CSI/m-p/752708#M117159 cankanbak 2018-06-05T15:03:16Z Re: iMX6 - How to connect GRAY16 format input through CSI https://community.nxp.com/t5/i-MX-Processors/iMX6-How-to-connect-GRAY16-format-input-through-CSI/m-p/752709#M117160 <HTML><HEAD></HEAD><BODY><P>Hi Can,</P><P></P><P>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.</P></BODY></HTML> Wed, 06 Jun 2018 14:24:00 GMT https://community.nxp.com/t5/i-MX-Processors/iMX6-How-to-connect-GRAY16-format-input-through-CSI/m-p/752709#M117160 Bio_TICFSL 2018-06-06T14:24:00Z
