I double checked the installation, I think it is ok. When I start the USRP, There will be two green lights on, several seconds later, 1 light off, and 1-2 seconds later, another light is also off.
also if there is a GPSDO installation problem, why *[INFO] [GPS] Found an internal GPSDO: LC_XO, Firmware Rev 0.929b appears?* Thanks.
