I've written a simple vhdl core to act as an EDID emulator.
It's basically a PLB Master core, catching interrupts from a PLB Slave XPS_IIC core attached to HDMI SDA/SCL line to manage I2C/DDC protocole.
This core works fine when xps_iic is connected to J3:IN I2C ports (M16 for SCL, M18 for SDA).
However, nothing happens when the xps_iic is connected to J1:IN I2C ports (C13 for SCL, A13 for SDA).
I guess I'm missing something with JP2 and JP4 jumpers.
Can you please tell me the correct jumper settings to have J1:IN hdmi port act the same way as J3:IN ?
Please note that I need for my project to have both J1:IN and J3:IN work together as I'm working with 2 video streams.
