Hi,
  When I take the dump of the buffer which is pointed by "DATA MEM
PING ADDRESS". It always shows 0x55.
  Even if i write 0x00 to the address. I do notice that it quickly
changes to 0x55.
  Under what conditions could this happen? What am i missing here.

  I do notice that the OMAP4 ISS is tested to work with OV5640 (YUV422
Frames) and OV5650 (Raw Data)
  When you say 422 Frames only. Do you mean 422-8Bit Mode?.

  I havent tried RAW12 which my device gives, Do i have to update only
the Data Format Selection register
  of the ISS  for RAW12?

  Please advice.
