I am answering my own question. A PULLUP on the RXD pin solved the problem. The floating RXD pin had value zero, what means data, and the processor was responding all the time, what seemed to block somehow the processor. With the PULLUP, floating RXD pin has a value of 1, what means no data, and processor is not overloaded any more. This PULLUP can be configured in the ucf file in EDK.
