DE10-standard ADV7180 read access

Hi, I’m currently trying to develop logic that tries to read ADV7180 internal registers using the I2C interface (i.e., I2C_SCLK and I2C_SDAT) using PIN_Y24 and PIN_Y23. Looking at the schemat...

This has been resolved by Terasic support. I've tried issuing read access to the ADV7180 using the hps_i2c_switch example and have verified that it works. Also, the pullup resistor is on page 10 of the schematic diagram. Although I haven't been able to use my own FPGA logic to access the ADV7180, but that is probably due to issues on my end such as not properly designing an I2C device, etc.
