OMAP3 ISP outputs 5555 5555 5555 5555 ...

Hello omap isp devs,

maybe you can help me, I am a bit desperate with my current cam problem:

I use a ov5642 chip and get only 0x55 in my data output when I use a
camclk > 1 MHz. With 1 MHz data rate from the camera chip to the omap
all works (well the colorspace is strange - it's greenish, but that is
not my main concern).
I looked up the data on the oscilloscope and all flanks seem to be
fine at the isp. Very clear cuts with 4 MHz and 10MHz. Also the data
pins are flickering fine. Looks like a picture.

I found that the isp stats module uses 0x55 as a magic number but I
don't see why it should confuse my readout.

I use 2592x1944 raw bayer output via the ccdc. Next to the logical
right config I tried all possible configurations of vs/hs active high
and low on camera and isp. The isp gets the vs flanks right as the
images come out in time (sometimes it misses 1 frame).

Anyone of you had this behaviour before?

Thanks so much for reading this,

Bastian Hecht
