I see..that was my guess too, just wanted to see if anyone ever ran into that too.
When adding the UART in the sopc I can assign to it an IRQ..Do you know if that will cause an interrupt every time a new byte will be recieved in the UART?
(of course I will have to make sure that the reading process will be faster than the baud rate)

Unless you're turning off interrupt handling (masking them) for long periods or you have Interrupt Service Routines taking longer than a few microseconds, there's no chance of not keeping up with 115200 baud even when using interrupts on unbuffered UARTs. However, buffered UARTs are MUCH more efficient because you can make them low priority interrupts and run faster than 115200. For the safest approach unless you absolutely need the serial speed, run somewhere slower like 38400 or 19200.
