 Not necessarily, can be a wrong connection, some part defective or just a bad soldering point.

 Do this test:

 Disconnet both RX and TX jumper from R3, get a wire and connect pin 1 with pin 4 of U3, see if you get echo in terminal, if so interface is ok, connect pin 2 with pin 3 of J3 and write a program that test both pin are ok, write H or L on tx and read from RX using digitalwrite.

 I assume Energia is using hardware UART and reversing jumper is not a good idea, so check port the we can do further  test.

I bought a new launchpad, and everything worked perfectly. It was really a hardware problem, probably I did something wrong in the past using a soldering iron. Thank you all for your help.
