Hi I am trying to detect a daughter card chip. From data sheet I was able to find the address for that chip. But when I use i2c probe command from uboot shell, it is showing me only 4 addresses. And these 4 addresses does not contain the address of any chip on the daughter card.
So my query is :

 1.  how can I detect the daughter card chips using i2c.
 2.  why i2c probe command is not showing the chip addresses for daughter card as mentioned on the data sheet. But that is giving the correct address of EEPROM.

Here I want to mention that the card is working fine but not able to identify the chips on the daughter card mounted on davinci evm board.
