Hello all:
I'm porting two ov4689 cameras to the i.MX 8MP board. (isp-imx-4.2.2.11.0 and isp-vvcam_imx_5.4.70_2.3.2)
Now channel 1 can get the image data, but channel 2 failed to get the data.
Here is the command to get the image, and the log of isp_media_server.
gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=1 ! video/x-raw,width=1280,height=720,framerate=60/1,format=YUY2 ! jpegenc ! filesink location=frame.jpg
In the red box is an error message. The normal execution message for channel 1 is wdr3 res: 1280 720, but I don't know why channel 2 is 0 0.
Can somebody, please help me on how I can make this work? Thanks in advance !
Regards,
Forest.
The attachment is the device tree file I used.

};
At present, I find the problem is that the isp driver failed to write a value to the register.
