Thanks, I did not read the errata (page 25) before programming the EEPROM - lesson lerned:
"Due to a factory configuration error, if the EEPROM has been programmed and then a POR is executed, both the Flash memory and EEPROM will be unable to be programmed"
However, my revision is G4 and your code just works for me as I have checked this morning.
Great job, Energia is a lot more simple, for me of course, than Code Composer or similar .
