pxa_camera + ov9655: image shifted on first capture after reset

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have updated my ov9655 driver to kernel 2.6.33 and
did some test regarding the image shift problem on pxa.
(http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/10773/focus=11810)

- The image was shifted 32 pixels (64 bytes) to the right
 or rather the first 32 pixels belongs to the previous image.
- The image was only shifted on the first capture after reset.
  It doesn't matter whether I previous change the resolution with v4l2-ctl.
- On big images (1280 x 1024) the shift disappears after some images,
  but not on small images (320 x 240).

It looks like the FIFO was not cleared at start capture.

Regards,
   Stefan
