I use same program struct like sct flexible camera solution AN11365, using lpc4350,the board m4 clock is 192mh(192/8=24MH),and change cmos chip to Ov10635, and transfer image via usb. the problem is the picture always with horizon line go from up to down (for high frequency) or from bottom to up(for low frequency). the ov10635 normal working xclk is 24MH, but only when I reduce the xclk to 12MH and below , the picture will ok. 

it seems that the href blank time is not long enough to deal with interupt ,which reload dma configuration.  hope somebody can help me.
