Hello,
I used the camera with raspbian Os and capturing images works, so the problem is not hardware related.
Now I created an rpi-test-image using yocto and want to capture an image using ov5647.
I added dtoverlay=ov5647 to /boot/config.txt
lsmod shows that the module ov5647 is already inserted, so all looks good
Linux versionrunning v4l tools shows following results:
trying to capture an image gives follwing error:dmesg show following problem:Can anybody give any hint on the problem ?
Thanks in advance
