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?
