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.
