The current instructions do not lead to functional capture on a i.MX6Q sabresd board. Fix the instructions so that users can get the OV5640 camera to work by default. Tested by two methods: 1. Using v4l2-ctl: # v4l2-ctl --stream-mmap -d /dev/video0 2. Using a Gstreamer pipeline that captures from the camera and direct the image to the display: # gst-launch-1.0 v4l2src ! kmssink Signed-off-by: Fabio Estevam <festevam@gmail.com> --- Hi Steve, Were the instructions written based on a i.MX6DL sabresd? I don't have access to a i.MX6DL sabresd board to confirm if they are still working, but I noticed that these instructions do not work on a i.MX6Q sabresd board, so that's why I modified it and now the capture works fine here. Please advise. Thanks Documentation/media/v4l-drivers/imx.rst | 24 ++++++++++-------------- 1 file changed, 10 insertions(+), 14 deletions(-)
