I downloaded the library and ran the SX_01a_TX_LoRa example. It worked fine and the messages appeared in the Serial Monitor. I don't have the shield to test if there is any change with it attached to the Galileo Gen1.
I had gotten the **B010000000063f694? error before, when serial data was received by the Galileo/Edison. In those cases, the error was caused because there was no line ending in each data received, like in this thread: How to communicate with arduino via wifi?. In other cases the error was solved just by resetting the sketch with the reset button (not the reboot button).
