I tried the example, but it still doesn't work.
It just doesn't send anything the Rx led doesn't blink and neither do the leds on the board turn on if I push the buttons.
I build it and I run it.
I don't know where to look also, I tried everything...
The board is also a couple of years old, but if I code in VHDL everything works fine.
