I have tried to assign the pins E1 to the HSMC_SDA and F3 to the HSMC_SDA signal in the assignment editor, but it still doesn't work. I only got a high or low level on my pins. It depends on which default values are choosen in the pin properties window. Instead of recieving signals I got the logic levels... Maybe I have to enable the pins first?
