Hi ,


We are using two ADV7182 decoder chips in our project, connected to same I2C line i.e 0 and

Have slave addresses 0x42 and 0x40 respectively.


For us ADV7182 having slave address 0x40 is working fine, but for ADV7182 having slave address 0x42 always we are getting only

test pattern even though we connect input.


Please find register configurations done for both adv7182 chips, and all registers dump containing log files

attached with this mail.


For Slave address 0x42 Log file name is ADV7182_42log.txt and for Slave address 0x40 log file name is  ADV7182_40log.txt


Please let us know what is the cause of this problem.


And please help us to resolve this.


Thanks & Regards
