Hi,
I verified vsync signal. As you mentioned it comes for 34ms.
For Ov7955 sensor, I am using VGA _YUV _30fps_ 24MhzPclk register settings provided by Omnivision technologies. I am checking with other register setting options.
I have checked ISIF registers. It seems OK to me. I shall cross check it again along with IPIPEIF registers.
Regards,
Arpitha
