LTC Connector DE10-Standard FPGA

I am trying to access the I2C bus on the LTC connector on the DE10 Standard FPGA board.  I have enabled the i2c controllers on the HPS. How do I now gain access to the i2c2 pins that are connected ...

Hello Kian,

Thank you for your response.

  1. It is revision C. However, it seems I've been referring to the schematics of rev b all this time. I could find only rev b schematics on the Terasic website. Could direct me to where I could find data on rev c boards?
  2. I wrote a c code for toggling the GPIO and probed the R306, however, there's no change. It doesn't toggle. It stays high. 
  3. When scanning the i2c bus, I see 0x53 which is the g-sensor since that is its device address. I don't see LTC connector.

Regards
