Rx dBoard has empty serial

Hello,

I was running the calibration routines for 3 USRP N210s and one 1 USRP
radio. I had them all connected at once to my computer and all of a
sudden
it says Error: RX dboard has empty serial!

How do I know which board has an empty serial and how do I fix this?

Does the calibration routines run for all of them @ once, when I call
the
program?

When you have more than one USRP device connected to your system,
you really should be explicit about which device you want to address,
using the “–args” option.

For your N210 it would be “–args
addr=192.168.X.Y” and for your USRP1 it would be “type=usrp1”

Otherwise, it just grabs the first USRP device it finds.

Hello,

I reran the command for each individual USRP radio connected.

Two of my USRP N210s have this output:

Error: RX dboard has empty serial!

One of my USRP N210 has this output:
Error: timed out waiting for TX and/or RX LO to lock

and the USRP1:

Error: self-calibration is not supported for this hardware.

I can understand if the self-calibration is not supported for the USRP1.

However, for the USRP N210s I would like these fixed. I ran
uhd_usrp_probe
and it seems like by dboard has a serial. It says TX Dboard: A ID:
WBX(0x0052).

Is there a bug in the calibration routines?

What version of UHD are you running? And what approximate age are
the WBX?

The Rev 3 WBX is somewhat different than Rev 2, so you need
to make sure that you have the latest host-side UHD and matching
firmware to properly support Rev 3 WBX.

There was a (transient) bug in
the calibration routines that was found last week, but it’s fixed in the
most recent UHD host-side.

I used the cal routines on my USRP2+WBX
just this past weekeend and they worked just fine. So perhaps you have
the transiently-broken version of UHD.

Perhaps Josh can comment–I
don’t have the GIT tags of the broken instance at my fingertips right
now.

I replaced my WBX boards with rev 3 and it looks like its working now.
However, I would still like to be able to run the calibration routines
on
the rev 2 versions. Are you guys going to support this?

My UHD version is UHD_003.004.000-325-g7e296167

I opened up my USRP N210s and it seems like on each board it says two
different rev numbers.

On all boards it shows WBX Board Rev. 2 on the main board while on the
connector board (the board with the RX and TX connectors on it) it says
WBX-FE-Simple Board Rev 4.0.

I think my boards are about a year old.

I installed gnuradio and uhd this saturday.

Jan -

UHD supports calibration of all WBX boards. The issue is that when you
bought your WBX, we weren’t burning serial numbers into that
daughterboard.
The calibration routine requires a serial number, because it uses it
to
save / identify the calibration data.

All you need to do is burn a serial into your daughterboard. UHD builds
a
utility called ‘usrp_burn_db_eeprom’ (host/build/utils), which you can
use
to set the serial of your daughterboard:

./usrp_burn_db_eeprom --unit=TX --ser=
./usrp_burn_db_eeprom --unit=RX --ser=

The serial you set can be any 9-digit ASCII string. After you write new
serials into your daughterboards, try the calibration again, and it
should
work fine.

Cheers,
Ben
