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 ...

Sorry for the delay in responding back, is it possible for you to probe the physical HPS_LTC_GPIO/GPIO40 to see whether it toggles when your code set the pin to low to confirm whether it is switching (via multimeter ?)

How about the I2C2 pin mux settings? Pins are assigned to HPS ?

Did a search on past topics and looks like there is some discussion on the clock , see whether is it similar issue

Thanks
