Unable to locate P1020RDB I2C pins

I want to use the functionality of I2C (as well as SPI) on the P1020RDB board. However, seeing the schematics, I'm unable to locate the exact pins I should be using for I2C. In the schematics, it says that the U41D IC is responsible for dealing with I2C and SPI. However, on my board there is only U41, and not U41A, U41B etc. Seems to me that I have the wrong assembly diagrams. However, I'm unable to find any other reference manuals as well.

I'm using the P1020RDB with the Red casing, and not this one https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRZqqsb1I5dUkv3cWx462t2nSWpXLuL-JBVwmpDfW4CtpoQ...

Any help would be appreciated.

Its P1020RDB RevD. There's a sticker on the back "SCH-26158 REV-D". I've got nothing else :smileysad:

Please open a technical case to obtain the RDB schematics:
