Hi Roberto,
what ccs version are you using? Have you been using the msp430 code size limted license? These might make a difference.
One thing to note is that v4 may not support the new devices. Both v4 and v5 ... if you use the code size limited license, you will need a separate licence/installation for the tiva series. However this is also a free license if you are using the xds100.
Best Regards,
Lisa
