I just solved it! If someone still has this problem, here is the solution.
This is only for JTAG Connection:
Open filWizard and launch Board Manager, select the board that you will use and clone it.
Then edit the copy that you just made. Remove the ethernet interface from the list.
Not sure what is the real issue , but I think that is due the ethernet interface call a the RTIOStream library, I found out that is for establish tcp communication.
You can try to modify the clock frecuency and pin number as indicated by user manual, I did this and works as well.
English is not my first language, so I beg your pardon for any mistake.
