Connect two DE2 boards via GPIO-Ports

I have connected two DE2 boards via an IDE-cable over the GPIO_0 ports. I want to use the analog video in from one board to transmit the data (TD_HS, TD_VS, TD_DATA) to the other board. I tri...

As far as I understand, you try to route bidirectional I2C signals through the FPGA. This doesn't work. Available I2C buffer IC are using special hardware features to detect the data direction of the signals. To "repeat" I2C by standard bidirectional I/O, you have to decode the protocol at the slave port and regenerate it at the master port.
