ov3640 driver tested with media-ctl and yavta

Hello,
I tried to use the ov3640 camera driver from Laurent Pinchart with the media-ctl and the yavta tools. I configured the pipeline as sensor -> ccdc ->memory. First I got problems with the CCDC module. it always said that the "ccdc won't become idle!", but it didn't restart by itself. So for testing I removed the waiting function which waits for the ccdc to become idle and tried again. Now I received some data from the buffers but the image is just black.
Any idea what my problem could be?

Best Regards, Tom

Hello,

I still have the problem that I don't receive any image data when the waiting function is commented in. I just get the "ccdc won't become idle" output. when this function is commented out and the polarities within the board-overo.c file are correct. I get some image data on which I can see the right structure but wrong colors.

Does anyone have an idea what the problem could be when the color is incorrect?
