Adv7611 read and write issues

Hello!

 

We are using ADV7611 and ADV7340 chips. we are not getting any acknowledgement from adv7611 chip address 0x98 or 0x4c (7 bit address) while writing and reading from i2c device using i2cset and i2cget tools. I am getting "read/write failed"  error no matter what register address is specified. besides the device is not getting detected with i2cdetect tool.

 

we also probed it with oscilloscope. are there any recommended settings before using i2c tools?

 

additional info:

I2C is running at 100 kHz

 

any help is much appreciated.

 

Thanks and regards,

Shivlal
