Video Input Daughter card (I2CA pin)

Hi, 

I'm using my Video Input Daughter (Altera) card (with two tvp5146 (http://focus-webapps.ti.com/general/docs/sitesearch/searchdevice.tsp?partnumber=tvp5146) connected via I2C) with my dk-NIOS-2s60n. I can access to first ADC with address 0xBA and I can't do it for second ADC with address 0xB8. I tried to pull-up pin I2CA of the first TVP, but it has no any effect.  

What is wrong? How correctly to configure (pull-up/pull-down) this pin before reset? 

 

Thanks for any help, 

Reva.
