Not able to program THS7303 amplifier through linux pro-4 kernal

Other Parts Discussed in Thread: THS8200, THS7303, TVP5146

Hi,

   We have interfaced VGA Encoder THS8200 to THS7303 from DM6446  for the VGA display in our custom board.

We have provided RC filter as per the data sheet of  THS7303 requirement .We are able to display SVGA image on Monitor from the test code we have written on CCS.

the same programming sequence we have included in the existing THS8200 linux driver for SVGA display.

We are getting error on I2C programming the THS7303. I have given the required  dummy clock cycles for THS7303 by sending 9 set of zeros, but still Iam I2C error with the existing I2C driver of PRO-4 kernal.

For other devices such as TVP5146 also Iam "I2C NACK Detected Error"

From RTC also Iam not able to read the data through I2C. Is there any path available for I2C correction ?

Please help me to resolve this issue..

 

Thanks and Regards

Deepthi Kiran
