Problems in OMAP 1510 Camera sensor code

Problems in OMAP 1510 Camera sensor code

[RAVI SHANGAR]

Previously, I got info about the 1510 camera driver that sensor_ov9640.c
must be modified for our ov66xx sensor.

But when I learnt ov9640 & ov6630 sensor specifications, they have more
similarities. Also the sensor code seems to be alright for atleast
*initialization
& detection* of ov6630 sensor chip.

When I tried with the camera driver, sensor initialization failed at
the *i2c_transfer(
)* function which returns -121 i.e., REMOTEIO error.

I am not aware of the significance of the error as well as where the source
of error lies ( with sensor code or sensor in camera itself).

The second doubt I have is the slave address for I2C driver used in ov9640.h

If OMAP_24xx_VIRTIO defined , addr is 0x60 or it is 0x30.

But in iBootHost given with OMAP board, Camera code uses 0x60 as the addr.

*QUERIES:*
*What's the exact address to be used? *
*In what places the sensor code is to be modified ?*
*I need to get MIDH and MIDL values from the sensor. Give the code changes
for this purpose atleast.*

Pl give a clear solution or sensor ov6630 code for OMAP camera  if
available.

Which sensor are you trying to support?  i am working on a driver for
the ov6650

For all the OV sensors I've seen (which it not that many!) the  default
slave address is 0x60
