HI,
I have ovm7692 mipi sensor connected on my custom imx7d-sabre board.
i am writing ovm7692 device driver by taking refernce of ov5640_mipi.c,
and also modified device tree for succesfull probe.
i am using mx6s_capture.ko, mxc_mipi_csi.ko to create /dev/videoX node.
when i execute the application /unit_tests/mx6s_v4l2_capture.out it gives me below error.
root:~# /unit_tests/mx6s_v4l2_capture.out
Found v4l2 capture device /dev/video0.
pixelformat (output by camera): YUYV
WxH@fps = 640x480@30 Image size = 614400
The output width or height is exceeding the resolution of the screen.
wxh: 640x480, screen wxh: 480x272
and if i redirect it in file using -of image.yuyv, it simply stuck and not responding.
can you please tell me
1) what is the reason behind this
2) do i have to insmod all ipu* drivers to make this functional
regards,
Akash

Hello,
What is result of the following command ?
# v4l2-ctl --list-devices
Note, the iMX7 does not contain IPU, therefore there is no need for IPU
drivers.
Have a great day,
Yuri
