Re: unexpected LookupError using gpsdo

Hi mleech, thanks for your help.

I have done the post-installation task by using the command :sudo
./usrp_burn_mb_eeprom --args=addr= --key=gpsdo
The terminal return:

Creating USRP device from address: addr=
– Opening a USRP2/N-Series device…
– Current recv frame size: 1472 bytes
– Current send frame size: 1472 bytes

Fetching current settings from EEPROM…
EEPROM [“gpsdo”] is “internal”

Setting EEPROM [“gpsdo”] to “internal”…
Power-cycle the USRP device for the changes to take effect.

I think the congfiure is successful. Then I use the GPS function of my
phone, It works. I think the signal of GPS satellite is also available.

But the lookuperror still exists. Why was that? Dose gpsdo can’t be
used in China?

It work well too.
Now I am confused . why is that happen? Was my gpsdo broken? All the two gpsdos
have the same LookupError.

Thanks for your help.

Did you do the post-installation task:

Also, the “gps_time” is only available once the GPSDO is locked to a GPS
satellite constellation–that’s where it gets the time from (and the
phase reference!).
